Redress Control Numbers

Officer with K-9 performing baggage inspection

The Redress Control Number (redress number) is a unique seven-digit identifier issued by the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP) and is used by the Transportation Security Administration's (TSA) Secure Flight program to match travelers with the results of their redress case. Secure Flight is a behind-the-scenes program that streamlines the watch list matching process. Airlines have modified their reservation system as part of the Secure Flight program. This improves the travel experience for all passengers, including those who have been misidentified in the past.

Quick Facts about Redress Control Numbers

  • If you feel that your request for redress was resolved incorrectly, please follow the instructions that you received in your resolution letter.

Not everyone has or needs a redress number. You will have a redress number if you have applied for DHS TRIP.

Booking Travel with a Redress Control Number

  • If you don't have a redress number and an airline or a travel site asks for your redress number, you can leave it blank.
  • If you do not have a redress number, you will still be able to make reservations and travel as normal. The redress number is an optional field and is not relevant for most travelers
  • You may provide your redress number when you make a reservation or when updating your airline profile.

Contact DHS TRIP

If you have applied for DHS TRIP and have lost your redress number, contact DHS TRIP at [email protected] .

Provide your full name, date of birth, gender, and city/state of residence. You will receive an e-mail containing your Redress Control Number.

What is a redress number for flying?

Do i need a redress number, how do i apply for a redress number, how do i use a redress number, redress numbers for tsa recapped.

Whenever you travel by air within, to or from the U.S., you’re electronically screened using the Transportation Security Administration Secure Flight screening program. While this system is transparent for most passengers, it occasionally misidentifies passengers as high risk.

If you've frequently been stopped for additional security during travel or have been denied travel for security reasons, you may consider applying for a redress number to avoid this in the future.

The redress number meaning is a numeric identifier given to individuals who were falsely identified as posing threats to transportation security or public safety when flying. It aims to streamline TSA checkpoints for these travelers.

Here's how redress numbers for travel work and if applying for one is a smart move for you.

The short answer is a redress number is an identifier that allows TSA to match you with the results of your redress case. A redress number is used by the TSA’s Secure Flight program to simplify the watchlist matching process and can prevent future false matches of people who have been misidentified as matching a watchlist in the past.

A redress number is different from a Known Traveler Number , which identifies your membership in Trusted Traveler programs like TSA PreCheck and Global Entry .

Most travelers won't have a redress number. Only people who have applied for the Department of Homeland Security’s Traveler Redress Inquiry Program, or TRIP, will have one.

If you don't have a redress number and an airline or travel site requests a redress number as part of a booking process, you'll simply leave that field blank.

If you've been denied travel or delayed during travel for additional security screening, or if you've had trouble getting through checkpoints at U.S. borders, DHS TRIP may provide relief from security-related travel woes.

Specifically, TSA suggests that you apply for a redress number if you've had issues like being unable to print a boarding pass, being denied or delayed boarding of a plane, being denied or delayed entry into or exit from the U.S. at a border checkpoint, or are frequently referred for additional screening at an airport.

Here is the list of issues that DHS says TRIP can help resolve:

You were unable to print a boarding pass from an airline ticketing kiosk or from the Internet.

You were delayed or denied boarding an aircraft.

The airline ticket agent informed you that the federal government was not authorizing you to travel.

You are repeatedly referred for secondary screening when clearing a U.S. Customs and Border Protection checkpoint or were denied entry into the U.S.

You were told by CBP at a U.S. port of entry that your fingerprints need to be corrected.

You wish to amend a traveler record because of an overstay as a result of not submitting the required I-94 when exiting the U.S.

You believe you were incorrectly denied ESTA authorization.

If you frequently experience issues like these when traveling, you might want to apply for DHS TRIP.

Note that TRIP is meant to resolve security-related issues like watchlist mismatches. It isn't intended to resolve customer-service complaints, address issues related to discrimination, help you find lost or damaged items or provide assistance during security screening.

Further, having a redress number doesn't guarantee that you'll never be selected for additional screening, but it makes additional screening less likely if you've been previously falsely matched to a watchlist.

You can apply for a redress number through the Traveler Redress Inquiry Program portal if you believe that you're being incorrectly stopped or screened when flying.

During the application process, you'll be asked a series of screening questions to determine if obtaining a redress number may help solve your travel issues.

To apply, you'll be required to submit ID documents proving your identity. U.S. citizens should provide a copy of the biographical page of an unexpired U.S. passport or, for those without one, a copy of an unexpired government-issued photo identification.

Minors may provide a copy of a birth certificate. Get more advice on how to successfully navigate TSA PreCheck with a family .

Non-U.S. citizens must provide a copy of the biographical page of an unexpired passport and/or copies of one of several U.S. government-issued identification documents. Acceptable identification documents include:

Passport card.

Driver's license.

Birth certificate (for people younger than 18.)

Military identification card.

Government identification card.

Certificate of citizenship.

Naturalization certificate.

Immigrant/non-immigrant visa.

Alien registration.

Petition or claim receipt.

I-94 admission form.

SENTRI card .

NEXUS card .

Border crossing card.

SEVIS card.

After the DHS receives and processes your application, it will send you a resolution letter detailing the outcome of your application. If you feel that your redress request was resolved incorrectly, you should follow the instructions in your resolution letter.

Making sure your redress number is attached to your air travel reservations will give you the greatest chance of avoiding security hassles when flying or crossing U.S. borders.

You can attach your redress number to a travel reservation during booking, you can add it to your frequent flyer profile or you can ask an airport agent to add your redress number to your reservation at check-in.

Enter your redress number during booking

Enter your redress number during the booking process when using most online travel agencies, airline websites or travel agents.

For example, when booking a flight on Expedia , you can enter your redress number after you provide your name, gender and date of birth. Look for the option to expand the “Frequent flyer, redress and more” section of this page.

Other online travel agencies and airline websites will typically have a similar option during their booking process.

Enter your redress number in your frequent flyer profile

If you belong to a frequent flyer program , you can add your redress number to your loyalty member profile. For many travelers, this is the most convenient way to ensure that your redress number is applied automatically to all their reservations. The process will vary by airline, but this can typically be done online, similarly to how you would add a known traveler number.

If you are a Delta Air Lines SkyMiles member, for example, you can add your redress number to the Secure Flight Info section of your profile. On Delta.com, your Secure Flight Information can be found under the Passenger Details section of your profile.

Similarly, Southwest Airlines members can enter their redress number under the “Travel related info” panel in the personal information section of their profile.

Exactly how to enter your information varies by airline, but the field to enter your redress number can typically be found in the same place where you enter your known traveler information.

Give your redress number to an airport agent

There may be times when you are unable to add your redress number to your reservation until check-in.

For example, if you book travel as part of a group tour package and your tour provider doesn’t provide your airline confirmation number, or if you booked through an online travel agency and forgot to add your redress number to your reservation, you may show up at the airport without your redress number attached to your reservation.

Most airport ticketing agents should be able to add your redress number to your reservation upon check-in.

While a redress number isn't required for travel and not everyone will need one, if you’ve experienced security-related issues while flying, applying for a redress number may be right for you. By adding it to your travel bookings or frequent flyer accounts, you can help TSA identify you to save time and stress.

What is a Redress Number? (And Do I Need One?) [2023]

If you’ve ever been slowed down at the airport by additional screening measures you know how frustrating (and even anxiety-inducing) it can be. Now imagine this happening just about every single time you make your way through an airport!

That’s what some people experience because the government has mistaken them for a nefarious actor or there has been some other hiccup with checking their background information.

Luckily for these people, there is something that they can do about this. It’s called getting a redress number and it’s actually pretty easy and straightforward to do. In this article, I’ll tell you everything you need to know about getting a redress number, including what the meaning is and when you should consider applying for one.

What is the meaning of a “Redress Number?”

A redress number is a case number issued by the Department of Homeland Security that allows individual agencies like the TSA to properly identify travelers that may have been misidentified as those who require additional screening.

Your name can also end up on a list requiring additional screening if you travel through certain countries, such as those in the Middle East.

The Department of Homeland Security set up a program to remedy these situations called the DHS TRIP and here’s what the DHS states about it :

Traveler Redress Inquiry Program (DHS TRIP) is a single point of contact for individuals who have inquiries or seek resolution regarding difficulties they experienced during their travel screening at transportation hubs—like airports and train stations—or crossing U.S. borders

Do I need a redress number?

As you can imagine, not everyone has issues getting through airport security and other ports of entry so not everyone needs a redress number.

One of the most common reasons for getting a redress number is when you’ve been subjected to secondary screening on multiple occasions . For example, you might constantly receive “SSSS” on your boarding pass and be forced to be searched in a special security area (likely receiving a pat down ) before boarding.

Here are a few other situations, based on DHS recommendations , when you might need a redress number:

  • You were not able to print a boarding pass online
  • You had issues getting a boarding pass from the ticket kiosk
  • You were denied or delayed boarding
  • A ticket agent called someone before handing you a boarding pass
  • You are on the “No Fly List”
  • You were denied entry back into the US
  • You were told your fingerprints were incorrect or of poor quality

Basically, anything related to getting access to boarding or making your way through an airport or port of entry that happens on a repeated basis may mean that you should look into getting a redress number. But the key here is that it happens on a repeated basis — if it’s an isolated event you probably don’t need a redress number.

SSSS on boarding pass

How to get a redress number

To get a redress number, you need to go through the DHS TRIP process and submit an application form. You can submit an application form online or you can print one out and submit it via mail. You might also print out your application, scan it, and then send it via email.

Filling out these applications is easy and will not require much of your time. 

There are two ways you can fill out the application.

Here’s what filling out the application form will entail.

Travel details

You’ll first be asked to provide details related to your travel issues on your application.

If you had issues with a flight you’ll fill out your flight information, such as:

  • Travel dates
  • Flight number

You’ll also be asked to check the type of issue you had, such as if you were denied boarding or subject to additional screening, etc.

(If you had multiple flights, provide that information in the Incident Details box.)

You can also provide information about your trip through ports of entry, immigration, customs, or border control. You’ll include relevant details like:

  • The date of entry
  • Name of airline or vessel
  • Port of entry into the US
  • Flight or cruise ticket number
  • Date of departure from the US

Finally, be sure to describe the incident or incidents related to your boxes checked in the Incident Details at the bottom of the page (up to 5,000 characters).

Identity information

Next, you’ll need to provide your identity information. This is very basic information. Just provide your name and other names if you have used other names in the past along with your contact information.

They also ask you to submit information about your travel frequency (questions like: “On average, how often do you travel each month?”).

Government-issued document

Next, you’ll need to provide information for the type of government-issued document that you’re going to send in. Make sure that it is legible and that it is NOT expired.

If you do not have a passport, you’ll need to provide a copy of at least one legible, unexpired copy of a government-issued photograph bearing travel document, such as a:

  • Passport Card
  • Birth certificate
  • Certificate of Citizenship
  • Drivers License
  • Government ID Card
  • Immigrant/Nonimmigrant Visa
  • Military ID Card
  • Naturalization Certificate
  • Global Entry
  • Alien Registration
  • Petition or Claim Receipt
  • I-94 Admission Number
  • Border Crossing Card
  • Additional Supplemental Documents
  • For children under the age of 18 who do not possess a photograph-bearing travel document, a copy of a birth certificate may be submitted
  • Do not  provide copies of Social Security Cards, Tax Information, or Personal Financial documents

Once you’ve entered in all of your information and submitted your application, you’ll need to print out the next screen and sign that page and send it in along with a copy of the ID you’re sending in as well.

You must send in your documents within 30 days of completing your application. 

Note that on that page you’ll see your Redress Control Number.

Sending in your documents

You can submit documents via mail or e-mail.

For expedited service, e-mail all requested documents to  [email protected] .

If your attachments exceed 10 MB, they will be rejected due to size limits so they suggest that you send separate e-mails with attachments using the same subject line.

You can mail in your documents to the address below:

DHS Traveler Redress Inquiry Program (TRIP) 601 South 12th Street, TSA-901 Arlington, VA 20598-6901

Submitting documents via mail will result in slower processing. In fact, due to federal government mail screening requirements it could take 10-15 business days for the government to receive your submission. 

travel number or redress number

How long does it take to get a number?

After your application and documentation have been received and verified for completeness, DHS TRIP will process your request and they state that the minimum length of a review of a request for redress is 30 business days.

The processing time can be much shorter than that though and some get their request approved in a matter of a couple of weeks or even days. However, the DHS has sent out emails telling others to expect processing times of 50 days or longer.

So the processing time can vary and it might depend on the nature of your request.

How to check your redress status

You can check on the status of your redress case application here .

Here are the different statuses your application might be in:

  • “In Progress”-  required documentation has been received and the redress process is underway.
  • “Closed”-  Any corrections or updates have been made, and a final response letter was mailed to you.
  • “Pending Paperwork” or “No Paperwork,”  – DHS TRIP has sent you a letter describing the additional information needed to complete your case review.

How to use a redress number

When you go to make a flight reservation, you should see a field to enter in your redress number. This is often close to the field for your Known Traveler Number. You can also add your redress number to your frequent flyer profile when you log-in as shown below with Southwest and United.

Alaska Airlines

Redress number vs Known Traveler Number

A redress number is different from a Known Traveler Number (KTN).

A  Known Traveler Number , also called your “KTN,” is a 9-digit number used to link your TSA Pre-Check enrollment to your travel itinerary. This is the same number used for other trusted traveler programs, such as Global Entry , NEXUS , and SENTRI . However, for these latter programs, this number is known as your “PASSID.”

TSA Pre-Check will allow you to make your way through security in a breeze by going through an expedited line and by not taking off your belt, shoes, light jackets, and keeping your liquids and electronics in your bag.

Global Entry will grant you expedited entry through US Customs and Immigration at ports of entry. Also, if you get Global Entry, it comes with TSA Pre-Check as well.

(By the way, there are several ways that you can get TSA Pre-Check /Global Entry for free and if you want to find out more about those options click here.)

The only relationship between a KTN and a redress number is that if you need a redress number and don’t have one, your KTN benefits like TSA Pre-Check and Global Entry might be affected.

Once you are given a redress number, you are still able to use your Global Entry and TSA-Pre Check benefits.

Redress Number FAQ

According to the DHS, the U.S. government does not reveal whether a particular person is on or not on a watchlist and the selection criteria is largely a secretive process.

Ninety-nine percent of individuals who apply for redress are not on the terrorist watchlist, but are misidentified as people who are. Also, there are two subsets of the terrorist watchlist which are the “No Fly” list and “Selectee” list: The “No Fly” list includes individuals who are prohibited from boarding an aircraft.  You are NOT on the No Fly list if you receive a boarding pass. The “Selectee” list includes individuals who must undergo additional security screening before being permitted to board an aircraft.

You can still get it retrieved by sending an email to  [email protected] /Redress_Number_Inquiry and providing your full name (including your middle name), current home address, and date of birth.

No, you do not have to be a US citizen to apply.

No, each person in a family or other traveling group seeking redress must submit a separate application.

If you’ve been burdened by extra security measures and you have repeatedly struggled to make your way through airport security, through the boarding process for planes and trains, or when getting back into the country, there’s a chance that you might need a redress number. It’s very easy to get if needed, so there’s really no reason why you shouldn’t give it a shot.

Redress number vs. known traveler number: understanding the difference.

travel number or redress number

In the world of customs and border protection, you may find some of the terminology unclear. For example, you may have heard of redress numbers vs. Known Traveler Numbers (KTN) in the context of airport security. But what do those terms mean and what are the differences?

What is a redress number?

Much like other travel identification numbers assigned by the government, a redress number is designed to expedite the border security process.

Redress numbers are issued by the Department of Homeland Security to individuals who have previously experienced difficulties during screening at transportation hubs such as airports. These difficulties may include watch list issues, screening problems at ports of entry and situations where a traveler believes they have been unfairly or incorrectly delayed, identified for additional screening or denied boarding.

If you do think you're eligible for a redress number, you can apply online through the Department of Homeland Security's website. After submitting your application, it will become subject to approval, which can take up to 50 business days.

Upon approval, you will receive your redress number, which you'll be able to use when traveling. This should help you avoid difficulties at security screenings going forward.

Note that if your security issues relate to a criminal record or an instance of excessive intoxication, you will likely not be eligible for a redress number.

What is a Known Traveler Number?

Separate from a redress number, a Known Traveler Number is issued to people who apply to and are approved for TSA PreCheck ® , the program that allows approved travelers to access expedited security lines for domestic travel in the United States.

Additionally, while the terminology is slightly different, a similar identification number is issued to those who apply to and are approved for Global Entry, NEXUS and SENTRI, programs that allow for expedited access into the United States via air, land or sea. In this case, you'll be issued a PASSID number, which is entered in the same place as the Known Traveler Number when booking air travel.

Like a redress number, a Known Traveler Number is also issued by the Department of Homeland Security, and recipients must go through an application and screening process to be approved. This then grants entry to the TSA PreCheck line, which allows travelers to go through airport security without removing liquids, laptops, shoes, belts or light outerwear.

Redress number vs. KTN: Differences and benefits

The main differences between a redress number and a Known Traveler Number are the circumstances in which it's issued and used.

A redress number relieves part of the stress of traveling by making it less likely you will be targeted for additional screening, or delayed or denied boarding or entry. Ultimately, the goal of a redress number is to create a smoother traveling experience for those who have had difficulties with security in the past. It works to correct the potential misidentification of travelers as high risk, thus complicating their experience through security.

By contrast, a Known Traveler Number allows travelers to access specially approved security lines and screening processes designed to expedite their wait time. Additionally, unless you are an active member of the military, you pay for this perk. TSA PreCheck costs $78 as of April 2023 for a five-year membership. This fee is subject to change, so be sure to check the TSA PreCheck website for the most up-to-date cost. A redress number, on the other hand, is free.

If comparing a redress number vs. a Known Traveler Number, you'll find the “why" behind the two numbers the biggest difference. Redress numbers are intended to correct misidentifications that may lead to security issues for certain travelers, while a Known Traveler Number is a travel perk you can pay for. Ultimately, their goal is the same — to help make your travel a little bit smoother.

TSA PreCheck and Global Entry are both very popular programs that can help you breeze through airport security checkpoints. You might have even heard of Mobile Passport or CLEAR — but have you heard of a Redress Number?

While a Redress Number won’t be necessary for the vast majority of travelers, it can be necessary to remove some of the stress of airport security for a select few.

Let’s take a look at all the things you need to know about the program so you can decide if it would be useful to you.

A Redress Control Number, more commonly known as a Redress Number, is actually a case number. The Transportation Security Administration (TSA) matches travelers to their case number via the Secure Flight program.

Occasionally, TSA’s Secure Flight program will misidentify travelers as a possible risk, which leads to additional security checks. If your name and information match that of another person who is on a watchlist, you might be misidentified.

A Redress Number can help prevent this from happening.

If you regularly have trouble getting through TSA security checkpoints or returning to the U.S. through Customs and Border Protection checkpoints, you should consider applying for a Redress Number.

While Global Entry and TSA PreCheck are great tools for travelers, they won’t prevent these inconveniences if your name is identified by Secure Flight for secondary screening measures.

The Department of Homeland Security (DHS) suggests a number of reasons why you should use the Traveler Redress Inquiry Program (TRIP):

Redress Number Reasons Part 1

The scenarios you might face when flying include:

  • Denied or delayed boarding
  • Repeatedly being identified for secondary screening
  • Received SSSS on your boarding pass
  • Unable to print your boarding pass at home or at an airport kiosk
  • Access your boarding pass on your mobile device

Redress Number Reasons Part 2

Additionally, at ports of entry, immigration, customs, or border patrol, you might run into issues such as:

  • Additional screening when clearing Customs and Border Protection
  • Denied entry into the United States
  • Your Electronic System for Travel Authorization (ESTA) application was denied
  • Unable to travel due to your status as a foreign student or exchange visitor

Fortunately, most travelers will not face these issues regularly, if at all. However, for those that do, a Redress Number could help provide a smoother travel experience.

Applying for a Redress Number

If you’ve decided that you might need a Redress Number, you can apply online or with a paper application.

Submitting an online application will be processed faster than an emailed or mailed application. If you plan to email or mail it, you must sign the document first. You can email the applications to [email protected] or mail it to:

DHS Traveler Redress Inquiry Program (TRIP) 6595 Springfield Center Drive, TSA-910  Springfield, VA 20598-6901 

It can take more than a month for DHS TRIP to process your application, so don’t hesitate to apply. DHS TRIP will notify you via email once they have received your application. This email will include your Redress Number in the subject line. Once a decision has been made, you will receive a letter in the mail.

Now, let’s go through the steps to apply. We’ll be using the paper application in this example, but you will need to provide the same information for the online application.

Redress Application Step 1

The first step of the application is to select the scenarios that you have experienced during your travels. While you don’t have to provide specific flight details of the incident(s) (including dates, airport, airline, and flight number), it does help DHS TRIP process your request.

You are required to select each scenario that you have experienced.

Redress Application Step 2

If you felt that your privacy was violated by an official or agent who exposed or inappropriately shared your personal information, this is the section to note that. If this is the case, you won’t need to provide more than your name.

Redress Application Step 3

In Step 3, you’ll need to explain any of the flight or privacy incidents for which you checked a box in Step 1 and Step 2. This section is required for DHS to review your application for a Redress Number.

Redress Application Step 4

Step 4 is where you will provide all of your personal information including full name, birthdate, birthplace, and gender. You’ll also need to share your height, weight, hair color, eye color, and whether you’re a U.S. person (legal permanent resident or U.S. citizen).

Redress Application Step 5

The contact information you need to provide is pretty simple. Just provide your mailing address and physical address (if different). You can also provide your email address, but this is optional. Providing your email address will make communication quicker if you choose to mail the application.

Redress Application Step 6

If you have an attorney or representative helping you with the DHS TRIP application, you can provide their name and contact information in Step 6. You will also need to authorize the release of information to this person. You can do this by completing the DHS Form 590  Authorization To Release Information To Another Person.

Redress Application Step 7

If you have a passport (unexpired), you can provide a copy of it in Step 7. Other eligible documents (with a photo) for the application include:

  • Passport card
  • Driver’s license
  • Birth certificate (only for those under the age of 18)
  • Military ID card
  • Government ID card
  • Certificate of citizenship
  • Naturalization certificate
  • Immigrant/non-immigrant visa
  • Alien registration
  • Global Entry
  • Border crossing card
  • Additional supplemental documents

DHS TRIP specifically mentions that you should NOT provide copies of Social Security cards, tax information, or personal financial documents.

Redress Application Step 8

If emailing or mailing your application, you will need to sign and date the application before sending; otherwise, your application cannot be processed.

Similar to how you use your Known Traveler Number for Global Entry or TSA PreCheck, you can save your Redress Number to your frequent flyer accounts or add it to your individual bookings

Unlike Global Entry and TSA PreCheck, using your Redress Number does not guarantee that you’ll be able to enjoy expedited security. However, you’ll at least be more likely to avoid getting SSSS on your boarding pass and being required to go through secondary screening.

Airport security is a hassle for everyone, but getting pulled for additional screening almost every time you travel can be a real inconvenience. While Global Entry and TSA PreCheck are fantastic tools to make the experience quicker, they won’t be able to help you if you repeatedly get the dreaded SSSS or are denied boarding.

If you regularly experience problems like those discussed above, applying for a Redress Number might be the right move for you. It doesn’t guarantee a quick security experience, but it certainly increases your chances.

Redress Number Guide

Frequently Asked Questions

What's the difference between a redress number and a known traveler number.

A Redress Number can help prevent you from being misidentified by the TSA’s Secure Flight program (which can lead to secondary screening, delayed boarding, or even denied boarding). A Known Traveler Number (KTN) is your membership number (or PASSID) with a Trusted Program such as Global Entry, NEXUS, SENTRI, or TSA PreCheck.

Is a Redress Number the same as a TSA number?

No, a Redress Number is different from a Known Traveler number (or KTN). A KTN is received from programs such as TSA PreCheck or Global Entry. A Redress Number is given by the Department of Homeland Security.  

Where do I find my Redress Number?

If you’re not sure if you’ve been given a Redress Number in the past or you’ve lost it, contact DHS TRIP directly at [email protected]. They can verify your identity and give you your Redress Number.

Do I need a Redress Number?

A Redress Number is not required to make reservations or to travel. It might be useful if you find yourself repeatedly selected for secondary screening or have been misidentified in the past.

What is a redress number? Do I need one?

Harriet Baskas

If you're a frequent traveler, you're likely familiar with trusted traveler programs such as TSA PreCheck , Global Entry , Clear and Mobile Passport .

The rules and benefits for each program vary, but they all offer travelers an expedited and, in many cases, a fast and hassle-free journey through airport security and/or the customs/border experience in exchange for some personal information and, in most instances, a fee.

If you sign up for TSA PreCheck or Global Entry (which includes TSA PreCheck status) through the U.S. Department of Homeland Security and are approved, you will be issued a Known Traveler Number (KTN) .

Add this number to airline reservations and to all your frequent flyer accounts to ensure your TSA PreCheck status appears on your boarding pass.

While forms often ask travelers for their KTN, as well as a redress number ("enter your Redress or Known Traveler Number here"), many travelers may be confused as to what a redress number is.

For more TPG news delivered each morning to your inbox, sign up for our daily newsletter .

The good news is that most travelers don't need to worry about getting or using a redress number. But here's an explanation of what it is (and isn't), why you'd need one, how to apply for and get it and when to use it.

What a redress number is not

First, let's clarify what a redress number isn't.

It's not the number of times you've had to take off your shoes, belt, jacket, winter coat, or heavy jewelry at the security checkpoint, put it all in a plastic bin, walk through the metal detector, and then get redressed on the other side.

That, as our friends at Milwaukee International Airport first dubbed it, is called recombobulation. You don't need a special number for that, just your attention so that you don't leave any of your belongings behind.

As mentioned above, your redress number is also not your TSA PreCheck number. Although, somewhat like a TSA PreCheck number, a redress number may help smooth your way through the security screening experience.

OK, so what is a redress number?

A redress number is what you'll need to seek out if you're constantly hassled by security issues when traveling.

It is the number, really a case number, the Department of Homeland Security can issue to you if you go through the application process and get a ruling under the DHS Traveler Redress Inquiry Program.

DHS describes the program as "a single point of contact for individuals who have inquiries or seek resolution regarding difficulties they experienced during their travel screening at transportation hubs — like airports — or crossing U.S. borders."

And the agency told TPG it has processed about 300,000 inquiries since 2007.

The DHS lists examples of "difficulties" including watch list issues, screening problems and "situations where travelers believe they have been unfairly or incorrectly delayed, denied boarding or identified for additional screening…"

Are you not actually on the government's watch list but are repeatedly pulled over for additional screening or did your airline inform you that the U.S. government will not authorize you to travel? Filing a complaint with the redress program — and getting a redress case number — might reduce or eliminate the hassles.

How to apply for a redress number

Apply for a redress number online (from your computer or mobile device) through the DHS TRIP program.

You must first take a "quiz" to determine if you really have a redress issue. If your travel issue is related to "discrimination; lost/damaged items or personal injury" or "assistance during screening for travelers with disabilities, medical conditions, and other circumstances," DHS will point you to another program.

travel number or redress number

If your issue or complaint falls under the DHS TRIP program parameters, you'll be sent to a login page to open a redress file, describe your travel complaint and share ID documents.

Before you start, make sure you have your current identity documents, such as your passport or driver's license, as well as information about the date, time and location of your travel incident.

travel number or redress number

What happens next?

Once you submit your application, DHS TRIP informs you it will process your request. According to DHS, the timeline for review "varies based on the concerns raised in the redress application."

You can track the status of your case in the DHS TRIP Portal.

Status categories include "In Draft," which means you've started an application but haven't completed it; "In Progress," which means DHS TRIP received your application and has put it in the review cue; "Info Needed," and "Closed," which mean you should have a determination letter in your file from DHS.

If DHS closes your case and decides to issue you a Redress Control Number, the agency suggests you add that number to all your airline reservations.

"Providing this information will help prevent misidentifications from occurring during security checks against government records and other information," says DHS. However, the agency warns that the DHS TRIP program cannot guarantee you'll always have smooth sailing after that.

Security measures outside of the redress process may sometimes require additional screening, DHS notes, adding that "while this process may sometimes be stressful, we rely on the patience, cooperation and understanding of travelers in such cases."

What happens after I submit my inquiry?

Once your application has been received and verified for completeness, DHS TRIP will process your request. The length of the review varies based on the concerns raised in the redress application.

How do I Track My Case?

You may track your case status under the "My Cases" section once you sign into your account in the DHS TRIP Portal. You will see one of the following statuses: In Draft  - You have started an application but have not submitted it. In Progress  - DHS TRIP has received your application and is reviewing your case. Do not resubmit your application. DHS TRIP will notify you or your representative via email (or postal mail, if email is not on file) and the status of your case will be changed to “Info Needed” (see below) if additional documentation is needed. If you have a DHS TRIP Portal account, log in and check the "My Tasks" section on your home page to see if your case has any outstanding requests for missing information. Info Needed  - Additional information is required on the application. If you have a DHS TRIP Portal account, log in and go to "My Tasks" on the home page to learn more about the missing information request and respond. Please respond to the missing information request as soon as possible to avoid automatic closure of the application after 30 days. Closed  - DHS TRIP researched and completed its review of your case.

Your letter is also available in the “My Files” section of the portal. If you do not have a DHS TRIP portal account, and you still have not received your final determination letter, please contact us at [email protected] .

How are the Results of Redress used?

DHS TRIP coordinates with its U.S. Government partners to ensure that relevant U.S. Government records are updated or corrected as appropriate. DHS TRIP recommends you provide your Redress Control Number when making airline reservations. Providing this information will help prevent misidentifications from occurring during security checks against government records and other information. DHS TRIP cannot guarantee your travel will be delay-free. Additional screening may occur due to issues outside the redress process. While this process may sometimes be stressful, we rely on the patience, cooperation, and understanding of travelers in such cases. The aim of these security measures is to safeguard the people of the United States and visitors to this Nation. If you have additional concerns please contact DHS TRIP at [email protected] . If you have already obtained a Redress Control Number and have additional questions regarding continued delays, please contact DHS TRIP directly. It is not necessary to obtain a new Redress Control Number to update your personal information or to report a new issue.

Am I on the Terrorist Watch list?

We have found that less than two percent of DHS TRIP applicants have a connection to the Terrorist Watchlist. Complaints most often arise either because the traveler’s name and personal information is similar to the name and personal information of another person (that is, a misidentification) or because the traveler has been delayed in travel for reasons unrelated to the Terrorist Watchlist, such as random screening. Using your Redress Control Number (RCN) when making airline reservation can assist in preventing misidentifications from occurring. For security reasons, DHS TRIP is generally unable to disclose whether you are or are not on the Terrorist Watchlist. The nondisclosure of the Terrorist Watchlist information protects the government’s operational counterterrorism and intelligence collection objectives, as well as the personal safety of those involved in counterterrorism investigations.

How will my privacy be protected?

The U.S. Department of Homeland Security (DHS) makes every effort to ensure the accuracy and security of travelers’ records. Information submitted through DHS TRIP will be protected and shared only in accordance with the provisions of the Privacy Act of 1974 (5 U.S.C. 552a) and the routine uses identified in Privacy Act System of Records Notice, DHS/All-005 Department of Homeland Security Redress and Response Records System (Federal Register), January 18, 2007. The Traveler Redress Inquiry Program Privacy Impact Assessment dated January 18, 2007, further details how DHS/TSA manages and safeguards the information it receives during the redress process. In addition, DHS enforces access restrictions and mandates privacy training for employees and contractors entrusted with managing this important information.

I have changed my name, received a new passport, or have moved. What steps do I need to take to update my information?

Please provide a legible copy of your updated passport and/or address to DHS TRIP via [email protected] and include your Redress Control Number. Upon receipt, your redress record will be updated accordingly.

Redress/TSA Pre✓®: Can I put the redress control number in the known traveler field of my airline reservation?

No. There are separate fields in which you may provide a Redress Control Number or a Known Traveler Number. These numbers are not the same, and it is important not to confuse one with the other. Redress Control Number - A Redress Control Number (RCN) is a 7-digit number that allows the U.S. Department of Homeland Security’s Traveler Redress Inquiry Program (DHS TRIP) to identify your redress application status. It is also useful when making reservations with an air carrier. An airline reservation system’s RCN field is an optional field and not required to make reservations. However, travelers with RCNs are encouraged to include this information when making reservations to help prevent misidentifications from occurring during security checks against government records and other information. Known Traveler Number - A Known Traveler Number is a 9-digit number that is associated with a Trusted Traveler Program, such as TSA Pre✓® Application Program or Global Entry. An airline system’s KTN field is an optional field and not required to make reservations. However, travelers with KTNs are encouraged to include this information when making reservations so that they may have an expedited screening experience. If you would like to learn more about trusted traveler programs, please visit https://ttp.dhs.gov .

Do I need a Redress Control Number?

Not everyone has or needs a Redress Control Number. - Travelers who do not have a Redress Control Number can leave this optional field blank when making airline reservations. -It is not necessary to have a Redress Control Number to make airline reservations. -If you do not have a redress control number, you will still be able to make reservations and travel as normal; the redress control number is an optional field and is not relevant for most travelers.

Can I submit one application for myself and my family?

Not everyone has or needs a Redress Control Number. Each person in a family seeking redress must submit a separate individual application). DHS TRIP cannot accept family or other group applications for any reason. Each individual seeking redress must submit a separate application along with a copy of a valid, unexpired travel document, e.g., passport. Each redress requestor may also apply online by visiting: https://trip.dhs.gov .

Known Traveler Number vs Redress Number – Everything You Should Know

Swati Jaiswal

Are you tired of long security lines and extra screening at the airport? Have you heard of Known Traveler Numbers and Redress Numbers but aren’t sure what they are or how they can help you? Understanding the difference between these two identification numbers can make your travel experience much smoother and hassle-free.

For frequent travelers, it’s important to understand the distinction between a Known Traveler Number and a Redress Number. In this article, we will explore the differences between these two identification numbers and how they can benefit you as a traveler.

Known Traveler Number vs Redress Number – What Is The Difference?

The Known Traveler Number (KTN) expedites airport security for TSA PreCheck-approved individuals. In contrast, a Redress Number addresses past TSA screening issues, preventing travel delays. In general, both streamline travel, but KTN is for pre-approved efficiency, while Redress tackles previous problems.

A Known Traveler Number (KTN) is a travel perk that some travelers can sign up for and pay an annual fee to receive. This number is registered with the Transportation Security Administration (TSA). 

Additionally, it is linked to a traveler’s frequent flyer profile, credit cards, and other travel information. 

When a traveler presents their KTN at the airport, they are identified as having gone through additional security screenings in the past and may be able to skip certain parts of the security process.

A Redress Number is issued by the Department of Homeland Security to a traveler who has experienced incorrect identification or encountered other security issues when traveling. 

This number is created after the individual completes a Traveler Redress Inquiry Program (TRIP) request form. 

When a traveler presents this number at the airport, it identifies them as having gone through additional security screenings in the past and helps to avoid further screenings.

Can You Use Both A KTN And A Redress Number?

Yes, you can have both a KTN and a Redress Number. These two identification numbers serve different purposes in the travel process. Having both a KTN and a Redress Number can help travelers streamline their travel experience by addressing both security screening and recurring travel issues.

How Do You Add Your Known Traveler Number (KTN) To Your New or Existing Ticket On United Airlines?

When checking in online or at the airport, there will be an option to enter your KTN. Simply input your KTN in the designated field, and it will be added to your ticket. This way, you can add your Known Traveler Number (KTN) to your new or existing ticket.

Here is a step-by-step guide on how to add your KTN on United Airlines:

  • Launch your web browser and open the United Airlines website .
  • Input your login details to log in to your account.
  • Go to your Mileage Plus Profile and input your Mileage Plus number and password .
  • You will be directed to the “Edit Traveler” section of your account.
  • Click the arrow sign next to the “Travel identification documents” tab.
  • Enter your KTN in the “Known travel number/Pass ID” box.
  • Click “Save” to confirm the addition.

Alternatively, you can add your Known Traveler Number (KTN) when booking a ticket or making an existing reservation on United Airlines. To do this, simply select the “ Add Known Traveler Number ” option when prompted .

Here’s a simplified list indicating the services that are allowed or not for Known Traveler Number (KTN) and Redress Number:

Why Do You Need A Known Traveler Number?

A Known Traveler Number (KTN) allows travelers to go through expedited security screening, avoiding long lines. Additionally, it obliterates the need to remove shoes, laptops, and liquids from their bags. This way, individuals can save time and have a more efficient travel experience.

KTN is especially beneficial for frequent flyers or those who value convenience and ease while traveling .

Benefits of Having a Known Traveler Number:

  •   The most significant advantage of having a KTN is that it allows you to bypass some additional security measures, such as secondary screenings and extra security screenings.
  • You’ll also be able to enter your KTN when booking airline reservations so that it will automatically appear on your boarding pass. 

This will save you time when you arrive at the airport since you won’t need to present any additional documentation.

  • Having a KTN can also make your travel experiences more consistent. 

When your KTN is associated with your frequent flyer profile, participating airlines will be able to recognize you and provide the same level of security screening each time you fly.

  • You may also be eligible for expedited service when returning to the U.S. at certain ports of entry if you have a KTN.
  • Finally, having a KTN may also qualify you for TSA Precheck, which allows you to quickly go through airport security without having to remove your shoes, belt, or laptop computer from your bag.

How To Get A Known Traveler Number?

To get a Known Traveler Number (KTN), you need to apply for a trusted traveler program such as TSA PreCheck or Global Entry. The application process involves completing an online application, paying a fee, and attending an in-person interview at an enrollment center .

What Is TSA PreCheck?

TSA PreCheck is a program offered by the Transportation Security Administration (TSA) in the United States. It allows pre-approved travelers to go through expedited security screening at participating airports. This program is designed to enhance the overall travel experience by providing a more efficient and convenient process for eligible passengers . 

With TSA PreCheck, travelers are able to keep their shoes, belts, and light jackets on, and are not required to remove laptops or liquids from their carry-on bags. 

This helps to save time and reduce the hassle of going through airport security checkpoints. 

To enroll in TSA PreCheck, individuals need to complete an application, undergo a background check, and pay a fee. 

Wondering why your TSA PreCheck is not working? Read this article to find out!

Here’s an example of a table showing the different costs associated with applying for TSA PreCheck in the United States:

What Are The Benefits Of TSA PreCheck?

The benefits of TSA PreCheck include shorter wait times at airport security checkpoints. Since PreCheck passengers are able to use dedicated lanes that typically have shorter lines. Additionally, PreCheck passengers do not have to remove their shoes, laptops, liquids, belts, or light jackets. 

TSA PreCheck makes the overall screening process much quicker and more convenient. This program also provides a greater sense of security and peace of mind for frequent travelers, as they are subject to less rigorous screening procedures.

Note 📝: Families with children 12 and under can accompany their parents or guardians through the TSA PreCheck line, even if they are not enrolled in the program.

But, can everyone in a group go through one TSA PreCheck? Find out in this article !

Follow the prompts and provide any necessary information to complete the process.

What Is The Redress Number?

A Redress Number is a unique seven-digit reference number issued by the U.S. Department of Homeland Security’s Traveler Redress Inquiry Program (DHS TRIP). This number is used to track inquiries made to DHS regarding difficulties travelers may have experienced when entering or leaving the country. 

The difficulties are basically, being denied boarding, delayed or searched at a port of entry, or having their visa denied.  

It serves as an efficient way to verify the identity of travelers and reduce confusion over reservations or other issues. 

Once a Redress Number is assigned, it will stay with the traveler for life and can be used to access TSA PreCheck or other trusted traveler programs. 

The DHS TRIP program works in collaboration with other government agencies. 

Together they help travelers get a resolution to their travel-related issues and improve the overall travel experience.

How To Get A Redress Number?

Generally, to apply for a redress number, you must first create an account at trip.dhs.gov . Once you have created an account, you will be asked to provide personal information such as your name, date of birth, and address .

Once you have created your account, you will be asked to provide additional information. 

The information may be your travel history, airline reservations, boarding pass numbers, or ports of entry. 

You may be asked to provide a copy of any driver’s license or other identification card that you use when traveling. 

Note 📝: You may also be asked to submit copies of birth certificates or credit cards associated with the traveler’s name.

After you have provided all the required information, the DHS will review your application and determine if they need additional information before issuing a redress number. 

Once your application has been reviewed and approved, you will receive a 7-digit redress control number (RCN). 

This RCN is what the Transportation Security Administration (TSA) uses to identify you in their system.

Why Do You Need A Redress Number?

One major benefit of having a redress number is that it helps to simplify the security screening process. If the TSA has your profile on file, then they are able to quickly verify your identity and reduce the likelihood of extra screenings or delays at airports. 

This can help save time and ensure a smoother travel experience.

Additionally, having a redress number can make it easier for travelers to update their frequent flyer profiles. It also ensures that their credit cards are properly linked to their reservations.

Who Needs A Redress Number?

A Redress Number is needed by individuals who have experienced difficulties or inconveniences while traveling due to mistaken identity. Moreover, the individuals who have been wrongly identified as a potential threat by security agencies. This number provides a means for these individuals to seek redress and resolve future travel issues.

It helps to streamline the security screening process and ensures that individuals are not wrongly targeted or inconvenienced while traveling.

We have listed some reasons why you would need a redress card:

  • If you have experienced any of the following, you may need a Redress Number:
  • Incorrectly matched or incomplete traveler information on your boarding pass
  • Frequent flyer profile mismatches
  • Secondary screenings at ports of entry due to travel documents, such as credit cards, birth certificates, or passports
  • Extra security screenings at airports due to travel screening issues
  • Additional security screenings due to false or incomplete traveler information
  • Delays in boarding an aircraft due to incorrect or incomplete traveler information

Do You Need A Redress Number If You Have Global Entry?

No, not every Global Entry member needs a redress number. However, if you have experienced multiple instances of being chosen for secondary security screening or frequently see “SSSS” written on your boarding pass, it is recommended to apply for a redress number. 

This will allow you to have any erroneous information removed from your file and help you avoid further issues. 

Note 📝: Having a redress number can provide a smoother travel experience and reduce the likelihood of being subjected to additional security measures.

Are KTN And Redress Number Benefits Guaranteed For Every Flight?

No, benefits are not guaranteed for every flight. While having a KTN or Redress Number can provide certain benefits such as expedited security screening or resolving issues related to mistaken identity or watchlist mismatches, it ultimately depends on various factors such as the airline, airport, and security protocols in place. 

Additionally, the availability and effectiveness of these benefits can vary depending on the individual’s circumstances and the specific situation.

Can You Use Your KTN Or Redress Number For International Travel?

Yes, you can use your KTN (Known Traveler Number) or Redress Number for international travel. TSA PreCheck® is available when you depart from a U.S. airport to a foreign country, and for domestic, connecting flights after you return to the United States. 

This allows you to enjoy the benefits of expedited security screening, such as keeping your shoes on and not having to remove laptops or liquids from your bag. 

Tip 📌: If you frequently travel internationally (four or more times a year), it may be more beneficial to enroll in Global Entry instead of TSA PreCheck® .

Are KTN And Redress Numbers the Same Thing?

In general, the answer is no, KTN and Redress Number are not the same thing. KTN, which stands for Known Traveler Number, is a unique identification number that is assigned to individuals who have been approved for the TSA PreCheck program. 

Whereas, a Redress Number is a unique identification number. It is given to individuals who have been mistakenly identified as a potential threat. 

Moreover, a redress number is given to individuals who have faced difficulties in traveling due to mistaken identity. 

In the realm of travel convenience and security, the disparity between a Known Traveler Number (KTN) and a Redress Number is clear. The former expedites screenings for pre-approved passengers, streamlining their journey. Meanwhile, the latter acts as a remedy for repeated travel disruptions due to identity misunderstandings. 

By comprehending their roles, travelers can make informed choices, ensuring seamless travel while mitigating unforeseen challenges.

Redress Number Vs Known Traveler Number: What’s The Difference?

  • By Patrick Davis
  • February 24, 2023
  • In Travel Tips

A redress number and a known traveler number are commonly confused. However, they are two very different numbers. Let's examine the differences between a redress number and a known traveler number.

A redress number is a unique identifier assigned to an individual subjected to adverse security screening in the past. This number allows the individual to avoid being unnecessarily targeted for additional screening in the future.

On the other hand, a known traveler number is given to approved travelers giving them expedited screening benefits.

As you can see, there are critical differences between the two numbers. In this article, we will take a closer look at these two airport security numbers and what they mean for travelers.

In addition, we will answer other questions about going through TSA, so read on!

Difference between access of known traveler number and readress number (2), Redress Number Vs Known Traveler Number: What's The Difference?

Is A Known Traveler Number The Same As A Redress Number?

Over the last 20 years, airport security has taken extra measures to ensure the safety of air travelers. This has included longer lines, more screenings, and additional measures for high-risk individuals.

The goal is to ensure that everyone who steps on an airplane is safe and not a threat to other passengers.

Known Traveller Number

The TSA has implemented several programs to help streamline the screening process for low-risk travelers, including the known traveler number [ KTN]  program.

The KTN program is available to U.S. citizens and lawful permanent residents who have undergone a background check and have been determined to be low-risk travelers.

Individuals with a known traveler number can use expedited screening lanes at select airports and are not required to remove shoes, belts, or light outerwear during the screening process.

In addition, known travelers are not required to remove laptops or 3-1-1 compliant liquids from carry-on bags.

Travelers with KTN can have children under 12 and adults over 75 included in their expedited screening privileges. You can apply to the KTN program on the TSA precheck website. 

Redress Number

A redress number is commonly confused with a known traveler number, but they are two very different things.

A redress number is given by the Homeland Security Travel Redress Inquiry Program [DHS TRIP] to individuals subjected to adverse security screening.

For example, if you have been delayed, denied boarding, or subjected to extra screening in the past, you may be eligible for a redress number.

This number will allow you to avoid being unnecessarily targeted for additional screening in the future.

While anyone can apply for a redress number, not everyone will be eligible. Keep reading as we will go into more detail about how to apply for a redress number.

How Do You Apply For A Redress Number?

Before you apply for a redress number, you should ask yourself if you are eligible. The DHS TRIP program is designed to help people who have been incorrectly identified as a security threat in the past.

For example, if you have been denied boarding an airplane or into another border crossing because you were flagged as a security risk, you may be eligible for a redress number.

In addition, if you have been repeatedly subjected to extra screening at the airport, you may be eligible for a redress number.

However, not everyone will be able to get a redress number. For example, if you have been denied boarding or subjected to extra screening due to a criminal record or were noticeably intoxicated, these are not reasons to apply for a redress number. 

If you think you may be eligible for a redress number, you can apply online through the DHS TRIP website. The application process is simple and only takes a few minutes to complete.

After you complete the application, it will go into review. From there, it can take 30 business days or more to get a response from DHS to determine whether you are eligible for a redress number.

Why Do People Randomly Get TSA PreCheck?

If you have seen people in the TSA PreCheck line and wondered how they got there, you are not alone. While some people may have applied and been approved for TSA PreCheck, others may have been selected randomly.

TSA randomizes passengers for PreCheck may be to increase the number of people who are enrolled in the program. By selecting people at random, TSA can hopefully have more travelers enroll in PreCheck, which can increase revenue.

Since the program is $78 for five years, it is not cheap. With that said, if more travelers can get a feel for how much time and hassle it can save, TSA may be able to convince more people to sign up.

If you are selected for PreCheck, you will be notified at the airport. You will be directed to the PreCheck line, where you can enjoy the expedited screening.

Is Getting A Known Traveler Number Worth It?

Getting a known traveler can have its benefits. However, whether or not you should pay for one will depend on how often you travel.

For example, if you rarely fly, you may not find the $78 price tag worth it. Now, for those who travel for a living or business, the $78 may be worth it, as you will use the PreCheck line more often.

The same can be said for those who frequently travel with young children or elderly adults. If you are constantly going through the airport with your family, the ability to have them all included in PreCheck may make the $78 price tag worth it.

Traveling with children can be stressful, so using PreCheck can help take some of the stress out of travel.

It is up to you whether or not you think getting a known traveler number is worth it. Since it's only for five years, you may decide to sign up and see how often you use it.

How Can I Find My Known Traveler Number?

When booking airline reservations, you may have noticed a field to enter your known traveler number. You can leave this field blank if you do not have a known traveler number.

If you have a known traveler number but cannot remember it, there are a few ways to look it up. First, you can log into the Trusted Traveler Program website . You can view all your account information, including your known traveler number.

Another way to look up your known traveler number is on your NEXUS, SENTRI, or Global Entry card. The nine-digit number will be on the back of each card and will start with 15, 98, or 99.

How Much Time Do You Save With A Known Traveler Number?

The amount of time you save with a known traveler number will depend on the airport you are flying into and out of.

For example, if you fly into a smaller airport that does not have PreCheck lanes, you will not save time. Since few passengers have PreCheck at smaller airports, the regular security line is often just as fast.

On the other hand, if you are flying out of JFK airport in New York, you can expect to save a significant amount of time by having PreCheck. These large airports will have long lines in the regular security lane, so having PreCheck can help you avoid a long wait.

It also depends on what time you arrive at the airport. The earlier you show up to major flights. If you show up before the TSA lines get too long, you may not save much time with PreCheck.

If you arrive at the airport and find that the regular security line is very long, having PreCheck can help you get through security much faster.

Sometimes it's hard to know how much time you will save with a known traveler number.

Why Do I Keep Getting Flagged By TSA?

Getting flagged for additional screening can be frustrating, especially if you have a flight to catch. However, there are a few reasons why you may be getting flagged.

First, it could be because of something in your profile. The TSA keeps a watchlist of people that may pose a threat to air travel. If your name or information matches someone on the watchlist, you may be flagged for additional screening.

Another reason you may be getting flagged is that you didn't abide by TSA rules in the past. For example, if you have tried to bring a banned item through security in the past, you may be flagged for additional screening.

You may also be getting flagged because of something random. The TSA uses a computer algorithm to randomly select people for additional screening. This is done to help keep air travel safe.

Sometimes you can have bad luck and keep getting flagged for additional screening.

Final Thoughts

Difference between access of known traveler number and readress number (2), Redress Number Vs Known Traveler Number: What's The Difference?

While they are two different traveler numbers, your known traveler number and redress number serve similar purposes. Both can help you get through airport security faster and make travel less stressful.

Travelers suffering from frequent security delays when traveling including secondary screenings, who are denied boarding or entry, or generally experience more hassle than other travelers when going through security checkpoints may need to file a redress case with the US Department of Homeland Security.

What is a redress number?

A redress number is a unique seven digit identifier issued by the TSA that helps verify traveler identity and prevent travelers from being misidentified. More accurately, a redress control number (RCN) is actually a case number referring to a passenger’s application for redress through the DHS TRIP program .

The DHS TRIP program provides a means for travelers to potentially reduce misidentification. The Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP) helps travelers clarify their identity with the Transportation Security Administration (TSA) so that they are no longer confused with actual watch list members.

DHS TRIP TSA Redress Control Number

In plain terms, the redress program is designed to assist travelers who may be incorrectly identified as someone on the TSA Watch List. By way of reminder, the TSA Watch List is a database of potential people who have been deemed a potential travel risk. It is different than the No Fly List which is a list of people who are explicitly banned from traveling.

In other words, a redress control number is a way for a traveler to say, “Hey, I’m not a bad guy, you are confusing me with someone else. Please stop hassling me at security checkpoints!”

If a traveler regularly finds themselves selected for additional screenings it is possible that they are being incorrectly identified by the TSA as someone on the TSA Watch List. Applying for redress through the DHS TRIP program may improve the traveler experience.

Redress means to remedy or set right, at least according to Merriam-Webster . In the context of air travel, it refers to a traveler’s ability to clarify their identity to the TSA so that their security checkpoint experience at airports and ports of entry is improved.

Most travelers will not need a redress case number. However, travelers who often find themselves selected for additional screening at airports and border crossings, regularly get the code SSSS on their boarding pass, are denied boarding, are unable to even print a boarding pass, or consistently have problems getting through federal security checkpoints and ports of entry could be incorrectly identified as a security risk. These travelers may need to apply for redress and if approved, obtain a redress control number.

Security Bins at Airport Security

Travelers should consider getting a redress control number if they find themselves consistently selected for additional security screenings, denied boarding on flights, or generally have trouble going through airport security screenings or ports of entry into the United States.

Travelers can apply for redress by submitting an inquiry to the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP). This program can help in providing resolution for passengers who believe they are incorrectly identified as a potential travel threat.

Passengers wishing to file a DHS TRIP inquiry must visit the DHS website and complete an online form . The form (sample snippet provided below) requires affected passengers to provide some information about the travel experience(s) in question as well as personal information and documentation regarding their identity including a government-issued ID with a photo.

How to get a redress control number from DHS TRIP

Within 30 days after submitting an application for redress, travelers must provide any applicable supporting documentation including copies of government IDs, etc.

Upon submission of an application for redress, travelers will be issued a redress control number regardless of how the redress inquiry turns out.

Travelers should use the redress control number to track the status of their redress inquiry and can visit the DHS TRIP “status” page for the current status of their redress case.

There are various reports about how long the redress process formally takes ranging from less than 30 days to 6 months to 50 days. The reported official answer from DHS is 50 days. However, as Lucky from OneMileAtATime reported back in 2017 his redress case was completed in a little less than 30 days.

Frequently Asked Questions about Redress Control Numbers (RCN)

In this section are numerous frequently asked questions (FAQs) about the DHS Redress Inquiry program.

How long does a redress case take?

Does everyone have a redress control number.

No. In fact, most travelers will not have or need a traveler redress number. Travelers who consistently experience delays in security screenings at airports, train stations, and other ports of entry may be incorrectly identified by the TSA.

Completing a DHS TRIP redress inquiry may be the best way to clarify your identity to the TSA and improve your travel experience.

A known traveler is an active participant in one of the known traveler programs such as TSA PreCheck, Global Entry, SENTRI, etc. Known travelers will be issued a Known Traveler Number or KTN.

TSA Precheck - a must do for your first business trip

If I have SSSS on my boarding pass do I need to get a redress control number?

Not necessarily. SSSS is a code indicating a traveler has been selected for secondary screening. Occasionally travelers will receive this code on their boarding pass for a variety of reasons including same-day air travel/booking, unusual travel patterns, randomly and of course, if the traveler is actually on a watch list.

Getting SSSS on a boarding pass once or twice or occasionally does not mean you need to fill out a DHS TRIP redress inquiry.

Getting it EVERY time you travel IS a good indicator you may need a redress control number.

How many digits is a redress number?

A redress control number (RCN) is seven digits long.

Can foreign nationals apply for a redress number?

Yes. Foreign nationals and non-US citizens can apply for a redress number. The redress control program is not limited to US citizens.

How do I add my redress number to my flight or travel profile?

Travelers must add their redress control number to their airline profile. When booking future flights the redress control number will be automatically added to the reservation and included on boarding passes. For existing reservations, it may be necessary to contact the airline to have a redress control number added to the reservation. Consult your airline for more details.

An example of where to add a redress control number for Delta Airlines is shown below using a Delta SkyMiles account (personal information blacked out) as an example. Each airline provides the ability for a traveler to include a redress control number in their profile.

How do I add my redress number to my flight

If I have a redress control number will I still be stopped for additional screening?

Possibly. While the redress inquiry program is designed to remove inconsistencies between a traveler’s identity within the Secure Flight program it is still possible that travelers with redress control numbers may occasionally be subjected to secondary screening.

However, with a redress case number, the number of instances of additional screening or security delays will likely be significantly reduced.

This program helps travelers who have been wrongfully flagged in the watchlist matching process to prevent future false matches. In addition, certain trusted traveler programs such as TSA PreCheck and Global Entry may require applicants to provide their redress number during the booking process .

If you don't have one, simply leave the field blank when travel site requests your redress number for verification purposes. The good news is that it won't affect your booking process if you do not have one. However, if you do experience difficulties when traveling due to possible watchlisting, applying for a redress number from Homeland Security's Traveler Redress Inquiry Program could be beneficial.

If you travel often, having a Redress Number can be essential for quickly identifying your trusted traveler status . A Redress Number is an 8-digit number that helps to easily identify travelers in the TSA PreCheck Program and other Trusted Traveler programs. It is also known as a Universal Enrollment Number (UEN) and is located on the top left corner of your Trusted Traveler Card.

When traveling domestically or internationally, having this number readily available is a good idea since it's used as an easy reference for traveler information . Your membership number in the Select Trusted Traveler program, such as Global Entry, serves as your Redress Number. Simply include this eight-digit number when booking flights to get quick response with regards to any security screening issues you may encounter. Alternatively, you could provide contact information if there are issues during check-in at the airport.

Using a Redress Number can make it easier to access essential information regarding your status as a trusted traveler and make international travel much more convenient. It is always wise to have this valuable information in hand whenever traveling domestically or abroad.

Travelers may come across a term known as redress or Redress Number while attempting to address travel issues. This number is issued by the Department of Homeland Security (DHS) and can be used to successfully navigate TSA Precheck. The Traveler Redress Inquiry Program portal is an application process that allows travelers to submit ID documents proving their identity, including a biographical page with unexpired government-issued photo identification such as a passport card, birth certificate, etc. for people younger than 16 years old. Military identification cards, government identification cards, naturalization certificates, alien registration claim receipt, I-94 Admission Form and Fast Card are all acceptable identification documents for non-US citizens. Moreover, documents like Sentri Card, Nexus Card and Border Crossing Card are also considered valid documents when applying for a redress number.

After DHS receives the necessary documents from the traveler – they analyze any possible errors that led to incorrect stops or screenings and send out a resolution letter detailing the redress request that was resolved incorrectly. Upon receiving this resolution letter – travelers can use their new redress number when making future flight reservations and benefit from TSA Precheck without unnecessary delays or further screening questions.

Redress numbers are essential for Americans traveling domestically and internationally as it allows them to fast track security screening processes saving time in both airports and immigration checkpoints around the world. With this in mind - if you have experienced any travel issues in the past - it's worth submitting an application for a redress number on the Traveler Redress Inquiry Program portal in order to successfully navigate TSA Precheck faster!

This 7-digit Code Could Save You From Extra Airport Security Screenings on Every Trip

No, not every traveler needs one — but here's how to find out if you do.

travel number or redress number

When you book a flight online, there's quite a bit of information you need to provide, from your email and phone number to your frequent flier number if you have one to your credit card details. It's fairly obvious as to what most of this is, but there's one piece that sometimes confuses travelers: a redress number. So, what is a redress number, and do you need one to travel? Here's what you need to know.

What is a redress number?

A redress number, formally called a Redress Control Number, is issued to travelers who are part of the Department of Homeland Security's Traveler Redress Inquiry Program (DHS TRIP). It's used to help travelers alleviate recurring security issues, whether they're regularly selected for secondary screening or have issues at the U.S. border. A redress number alerts the Transportation Security Administration (TSA) that a traveler may be incorrectly added to a security watch list, which happens on occasion.

Do you need a redress number to travel?

No, travelers do not need a redress number to travel. But if you find yourself frequently having security issues when flying or crossing the U.S. border, you may want to apply to DHS TRIP to smooth out the travel process. According to the DHS , "People who have been denied or delayed airline boarding; have been denied or delayed entry into or exit from the U.S. at a port of entry or border crossing; or have been repeatedly referred to additional (secondary) screening can file an inquiry to seek redress."

How do you get a redress number?

You can apply for a redress number at trip.dhs.gov . The website also has a helpful quiz to help you determine whether or not you need a redress number. Keep in mind you may be rejected based on your application.

Is a redress number different from a Known Traveler Number (KTN)?

On booking forms, spaces for redress numbers and KTNs are usually located near one another — or sometimes even on the same line — but they're not the same and used for different purposes. While redress numbers are used for travelers who have successfully applied to DHS TRIP, KTNs are part of the Global Entry and TSA PreCheck programs , which expedite entry at U.S. borders and TSA airport security , respectively. More travelers have KTNs than redress numbers, but it's possible to have both.

Known Traveler Number vs Redress Number – Everything You Should Know

Jannat Nauman

Are you tired of long security lines and extra screening at the airport? Have you heard of Known Traveler Numbers and Redress Numbers but aren’t sure what they are or how they can help you? Understanding the difference between these two identification numbers can make your travel experience much smoother and hassle-free.

For frequent travelers, it’s important to understand the distinction between a Known Traveler Number and a Redress Number. In this article, we will explore the differences between these two identification numbers and how they can benefit you as a traveler.

Table of Contents

Known Traveler Number vs Redress Number – What Is The Difference?

Yes, let’s simplify the difference between a Known Traveler Number (KTN) and a Redress Number:

Known Traveler Number (KTN):

A Known Traveler Number (KTN) is like a golden ticket for travelers who want to speed through airport security. You sign up for it, often with an annual fee, and it’s registered with the TSA.

It’s linked to your frequent flyer profile, credit cards, and other travel info. When you use your KTN at the airport, it tells security that you’ve already gone through extra screenings in the past, so you might get to skip some security steps.

Redress Number:

A  Redress Number is more like a solution for travelers who’ve had issues with security before. It’s given to you by the Department of Homeland Security when you’ve faced problems with identification or security during your travels.

You get a Redress Number after you fill out a form called the Traveler Redress Inquiry Program (TRIP) request.

When you show your Redress Number at the airport, it lets security know that you’ve had extra screenings before, which can help prevent more delays.

So, in a nutshell, a KTN is for smoother future travel, and a Redress Number is for fixing past travel hiccups.

Can You Use Both A KTN And A Redress Number?

Yes, you can have both a KTN and a Redress Number. These two identification numbers serve different purposes in the travel process. Having both a KTN and a Redress Number can help travelers streamline their travel experience by addressing both security screening and recurring travel issues.

Additionally, the availability and effectiveness of these benefits can vary depending on the individual’s circumstances and the specific situation.

Yes, you can use your KTN (Known Traveler Number) or Redress Number for international travel. TSA PreCheck® is available when you depart from a U.S. airport to a foreign country, and for domestic, connecting flights after you return to the United States.

This allows you to enjoy the benefits of expedited security screening, such as keeping your shoes on and not having to remove laptops or liquids from your bag.

Are KTN And Redress Numbers the Same Thing?

In general, the answer is no, KTN and Redress Number are not the same thing. KTN, which stands for Known Traveler Number, is a unique identification number that is assigned to individuals who have been approved for the TSA PreCheck program.

Whereas, a Redress Number is a unique identification number. It is given to individuals who have been mistakenly identified as a potential threat.

Moreover, a redress number is given to individuals who have faced difficulties in traveling due to mistaken identity.

In the realm of travel convenience and security, the disparity between a Known Traveler Number (KTN) and a Redress Number is clear. The former expedites screenings for pre-approved passengers, streamlining their journey. Meanwhile, the latter acts as a remedy for repeated travel disruptions due to identity misunderstandings.

Everything to Know About a Redress Number

' src=

Thanks to the  transportation security administration (TSA), flying today is “safer” than it was pre-9/11. The TSA still fails 95% of tests , but through technology and do not fly lists, the government and TSA would like you to think that you are safer. Despite this, the TSA screens millions of flyers each year and the security process is increasingly more invasive and time-consuming. To speed up screening of passengers both flying and entering the United States, the US government and private companies offer different programs to travelers.  Each program is trying to take the hassle out of flying.

travel number or redress number

Most people who travel often know of TSA PreCheck and Global Entry. Both programs are heavily advertised at airports and in-flight and even many credit cards provide reimbursement for these programs. Clear , a private company is also trying to make a comeback nationwide. Yet, there is also another program which is free, but it is only going to make a select few travelers’ lives easier. This program provides a Redress Control Number to flyers. It is a program through the Department of Homeland Security (DHS) and depending on your travel habits and headaches, you may want to consider applying for a Redress Number.

What Is a Redress Number?

A redress number is not the same as TSA PreCheck or Global Entry. Even if you apply for a Redress Number you are not guaranteed PreCheck or expedited screening while flying into the United States. The redress number is just another traveler number which can be saved in the air traveler’s profiles and placed on each plane ticket to reduce misidentification. Individuals with a Redress Number are more likely to receive standard screening instead of additional screening, such as the horrid SSSS experience . Frequent flyers who do not have problems while traveling should not need to apply for a Redress Number. If you want pre-clearance and PreCheck, apply for Global Entry .

How to Apply for a Redress Number

A Redress Number can only be applied for directly through the Department of Homeland Security online at trip.dhs.gov . The process is very easy and requires filling out a simple 3-page form . On the form, you select why you think you need a redress number and explain to DHS the issues you have had while traveling. After completing the form online, and providing a lot of personal information, you must print and sign the form and either mail it or email it to [email protected]. Be sure to include a copy of your passport or photo ID when submitting the application. You can also print the application, fill it out with a pen, and then scan it to a computer. At time of submission you will get a redress control number. This will become your Redress number.

The current wait time for a redress number is approximately 50 days. Or at least this is what the stock email claims from DHS. However, I applied for a redress number on June 26, 2017 and my case was processed and approved on June 30 th .  Despite the speedy approval, my notice did not arrive until July 10th.

Do note, that once DHS has processed your application, you are assigned a Redress Number. The Redress Control Number is on the subject line of the email from DHS letting you know that they have received your application. I recommend applying the number immediately to all reservations. As your case may process faster than the 50 days quoted.

How to Use a Redress Number

A redress number is not the same as TSA PreCheck or Global Entry. Even if you apply for a Redress Number you are not guaranteed PreCheck or expedited screening while flying into the United States. The redress number is just another number which can be saved in traveler’s profiles and placed on each plane ticket to reduce misidentification. Individuals with a Redress Number are more likely to receive standard screening instead of additional screening, such as the horrid SSSS experience . Frequent flyers who do not have problems while traveling should not need to apply for a Redress Number. If you want pre-clearance and PreCheck, apply for Global Entry .

Should You Get a Redress Number?

If you are not having issues while traveling there is no reason to get a Redress Number. If you find that you constantly have trouble with either the TSA or entering the USA from abroad, a Redress Number is appropriate. Anyone can apply for a Redress Number, the program is not only for US Citizens. Even if you have PreCheck or Global Entry, a Redress my be necessary.

The most common reasons to apply for a Redress Number include:

  • Always subjected to additional screening when going through an airport security checkpoint.
  • Being denied boarding.
  • Inability to print a boarding pass at the airport kiosk or at home.
  • Must check in at a ticket counter each time you fly.
  • An airline agent saying that you are on a Federal Government Watch List.
  • Being detained during a travel experience by the TSA or U.S. Customs and Border Protection (CBP).
  • Being repeatedly referred for secondary screening when clearing CBP.
  • Being refused entry into the United States.
  • CBP reports that your fingerprints were incorrect or of poor quality.

There are several other reasons one can apply for a Redress Number. The above list is only a few of the common reasons why people request a Redress Number. If you have difficulties traveling, consider a Redress Number, but also consider Global Entry. Since travel though through Istanbul, and having security issues ever since, I now have both. Every Frequent Flyer profile has my Known Traveler ID Number (Global Entry) and my Redress Number saved. This allows all agencies to communicate and hopefully reduces the risk of extra security screening after visiting “suspicious” places. Currently most passengers who visit Turkey and/or Egypt are subjected to weeks of extensive SSSS security screenings. Even long time travelers with Global Entry and PreCheck.

Final Thoughts

I can say, I never thought I would need a Redress Number, but having one has been a godsend. It has been six weeks since I transited through Istanbul and traveling is back to “normal” for me. The minute I applied for a Redress Number and applied the case number to my reservations, the SSSS dropped from my boarding pass. Although I was on Holiday and did not fly between June 26 and the 30th! As a frequent flyer, I clear security 2-4 times a week, and not having PreCheck was painful. The extra time it took to check-in with an agent and having an extensive security screen due to the SSSS wasted at minimum of 2-3 hours of time each week. Getting a Redress number was the best thing that has happened to me in 2017. Only because everything seems normal again!

If you travel, even if infrequently, but find yourself constantly subjected to extra security checks, apply for a redress number. It will result in a massive time-saving and reduce your stress on your next trip.

Get All The Details About The Redress Number And How To Apply

While booking your international flights to India from USA you must have stumbled upon the term “redress number” and multiple questions like “what is a redress number?” must have come across your mind. Don’t worry, though! Flyopedia has covered everything you must know about redress numbers in this blog, and we describe it in more detail below.

When you fly, going through airport security may be an incommodious and lengthy process. If you ever have to go through further screening and get pulled aside for inspection each time you travel might be problematic Nobody wants to experience difficulties while traveling especially when you are going to board long-haul flights to India from USA. In situations like these, the redress number might be your lifesaver and speed up and streamline airport security operations. Getting a redress control number would be a smart decision even if the airport screening goes smoothly and there are no problems.

A Redress Number: What Is It?

The Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP) issues redress numbers, which are distinctive 7-digit record identifiers, to travelers who have asked for redress for troubles they encountered during travel security screening. It enables the TSA to verify the passenger’s identity and eliminate watch list misidentification.

TRIP Program of DHS

A single point of contact for travelers with questions or problems they encountered during their travel screening at airports and railway stations is the DHS Travel Redress Inquiry Program (DHS TRIP). Using DHS redress numbers prevents the government from mistakenly identifying travelers. It resembles the passenger numbers needed for TSA Precheck or global admission quite a bit. However, using this number does not ensure faster security on international flights to India from USA but it aids in your ability to pass secondary screening and security inspections without incident.

Known Traveler Number vs. Redress Number (KTN)

An eight-digit code, known as a Known Traveler Number (KTN), connects your TSA Pre-check registration to your travel plans. The same number serves for NEXUS, Global Entry, and SENTRI, among other reputable travel programs. This number is your “PASSID” for these programs. Furthermore, a redress number serves as a special identifier enabling the TSA to correctly identify travelers who may have been mistakenly labeled as needing further screening on flights from the USA to India.

How Can I Acquire A Redress Number?

If you consistently experience issues with the screening or identification procedures carried out by airport workers, you can ask for a redress number to prevent similar inconveniences in the future. It will take less time to process your application if you submit it online as opposed to by email. Additionally, you must sign all of the documents you are attaching if you wish to submit an email to obtain a redress number. The time it takes to process a mailed application can exceed a month. Once we receive your application, you will be notified through email. Furthermore, your redress control number will be sent to you by email after the proceedings are completed.

You must do the following actions in order to submit your application without any errors:

Step 1: List your travel experiences as the first thing you do when submitting your application. You must include all relevant information regarding your trip, including the airline, airport, and flight number. For instance, if you have reserved flight tickets to India from the United States, you must include the date of the flight, the flight number, the name of the airline, and the airport (departure & arrival).

Stage 2: The second stage provides a box with information about privacy infringement. You can check the box if you ever believe that airport personnel has shared your private and highly secret information with anyone. When requesting a redress number for this exclusive purpose, only your name is required.

Stage 3: In the third step, you must elaborate on your flight experiences and privacy incidents. The boxes you checked in the first and second steps are enforced in this stage.

Phase 4: Your personal data is the focus of this step. You must enter all of your personal information, including your name, birthdate, age, place of birth, height, gender, hair color, eye color, and any other distinguishing characteristics or identification features. You must also state whether or not you are a citizen of the United States.

Step 5: In the fifth step, you must include both a physical address and a mailing address. A valid email address will also be required but it is not mandatory.

Step 6 – The sixth step is necessary only if it applies to you. If you know an attorney or other person who is helping you with this DHS TRIP, please include his name and contact information. Before disclosing that person’s information, you must have their consent. Additionally, DHS form 590 must be completed for this.

Step 7: Document identification is done in this. It requires a copy of your current passport as well as a few other official identity documents. The following documents are required:

  • Passport and Driving Permit
  • Birth Certificate and Certificate of Citizenship (if you are under 18)
  • Military and official identification cards and a visa for immigrant and non-immigrant
  • Alien Registration
  • Border Crossing Card with a Picture of a SENTRI, FAST, NEXUS, or Global Entry

Step 8: If you are sending your application by mail or email, you must acknowledge it by signing it and including the date of submission. Your application won’t be accepted by the authorities if it is unsigned.

What situations call for a redress number?

You can file an inquiry and request a redress number if you’ve been selected for further screenings on multiple occasions to ensure it doesn’t happen again. You can submit a request for information with the DHS if you’ve encountered problems in any of the following areas of airport control:

  • Having trouble navigating TSA checks
  • Having difficulties navigating Customs and Border Protection checks
  • Situations in which you had to undergo further screening at the airport

If a representative at the airport delays or refused your boarding, you can also use the Traveler Redress Inquiry Program (TRIP).

If an airport, security, or customs official informed you that your information was inaccurate, that your fingerprints and photo ID didn’t match your identity, or that you were on a no-fly list, this situation is particularly urgent. In these situations, you should submit an application to the DHS as soon as possible rather than only thinking about acquiring a redress number.

How long does it take to receive a redress number?

DHS TRIP will process your request after receiving and verifying your application and supporting documents. Depending on the type of request, the review of a request for redress must last at least 30 working days.

The processing time, however, can be considerably less; some people are able to have their requests accepted in as little as a week. Nevertheless, delays have occasionally resulted in requests taking up to 50 days.

How do I utilize a complaint number?

You should notice a field to enter your redress number when booking a flight, usually next to the space for your Known Traveler Number. On the website of your preferred airline, you can also add your redress number to your frequent flyer profile.

How do I update my flight or travel profile to include my redress number?

Your flight or travel profile must include your redress control number. By following this process, you can add the redress control number to your reservation and have it printed on your boarding ticket for upcoming flights. If you were issued a redress number after making existing reservations, it might be necessary to contact the airline to add the redress number to those reservations.

Frequently asked questions.

Introduction

Welcome to the world of travel! Whether you’re a seasoned globetrotter or a novice explorer, it’s no secret that navigating airports and dealing with security protocols can sometimes be a hassle. However, there are a few handy tools that can help streamline your travel experience and make your journey that much smoother. Two such tools are the Known Traveler Number (KTN) and the Redress Number. In this article, we’ll explore what these numbers are, how to obtain them, and the benefits they offer.

With the ever-increasing number of travelers, security measures have become more rigorous in airports around the world. The Transportation Security Administration (TSA) in the United States, for instance, has implemented various pre-screening programs to expedite security clearance for trusted travelers. This is where the Known Traveler Number comes into play.

The Known Traveler Number is a unique identification code assigned to individuals who have undergone pre-screening and background checks through programs such as TSA PreCheck and Global Entry. These programs allow for expedited security screening, enabling eligible travelers to enjoy perks like using dedicated screening lanes, keeping their shoes and light jackets on, and leaving their laptops and liquids in their bags during the screening process.

Understanding Known Traveler Number

In order to fully understand the significance of the Known Traveler Number, let’s dive into its details. As mentioned earlier, the Known Traveler Number (KTN) is a unique identification code that is assigned to individuals who have been approved for trusted traveler programs such as TSA PreCheck or Global Entry.

When you apply for TSA PreCheck or Global Entry, you will undergo a rigorous background check and fingerprinting process conducted by the TSA or U.S. Customs and Border Protection (CBP) respectively. Once you are approved, you will receive a Known Traveler Number that is valid for a specified period of time, usually five years.

This unique number is used to verify your eligibility for expedited security screening when you travel. When making a flight reservation or checking in online, you will enter your Known Traveler Number in the appropriate field. This allows the TSA or CBP to identify you as a trusted traveler and grant you access to the expedited security screening lanes at participating airports.

It’s important to note that the Known Traveler Number is only applicable for domestic travel within the United States. If you plan to travel internationally, it is recommended to apply for Global Entry, as this program includes all the benefits of TSA PreCheck and also offers expedited re-entry into the United States through automated kiosks at select airports.

Having a Known Traveler Number can save you valuable time and make the airport experience more convenient. Instead of waiting in long security lines, you can breeze through dedicated lanes with minimal hassle. This means less time spent removing your shoes, belt, and jacket, and less time unpacking your laptop and toiletries from your carry-on bag.

Additionally, many frequent travelers appreciate the added convenience of keeping their electronics and liquids in their bags, reducing the risk of items getting lost or damaged during the screening process. Overall, the Known Traveler Number is a valuable tool that can greatly enhance your travel experience, allowing you to spend more time enjoying your journey and less time dealing with airport security protocols.

How to Obtain a Known Traveler Number

If you’re interested in obtaining a Known Traveler Number to enjoy the benefits of expedited security screening, here’s a step-by-step guide on how to get one:

  • Start by deciding which trusted traveler program is right for you. The two most well-known programs are TSA PreCheck and Global Entry. If you only plan to travel domestically within the United States, TSA PreCheck may suffice. However, if you frequently travel internationally, Global Entry is recommended as it includes TSA PreCheck and offers expedited re-entry into the United States.
  • Visit the official website of the chosen program to begin the application process. For TSA PreCheck, you would visit the TSA PreCheck website, and for Global Entry, you would visit the CBP Global Entry website.
  • Complete the online application form with accurate personal information and pay the non-refundable application fee. The fee for TSA PreCheck is typically around $85, and for Global Entry, it is around $100.
  • Schedule an appointment at an enrollment center for an in-person interview and background check. During the interview, you will need to provide valid identification documents as proof of your identity and citizenship.
  • Attend the in-person interview at the designated enrollment center. The interviewer will ask you questions related to your application and conduct a thorough background check, including taking your fingerprints.
  • Once your application is approved and the background check is complete, you will receive your Known Traveler Number via email or mail. This number is unique to you and can be used for the specified duration of your program.
  • When making flight reservations or checking in online, enter your Known Traveler Number in the appropriate field to ensure that you receive the benefits of expedited security screening.

It’s important to note that the application process and timelines may vary depending on the program and your location. It’s advisable to apply well in advance of your planned travel to allow sufficient time for the processing of your application and the scheduling of your in-person interview.

Once you have your Known Traveler Number, you’re ready to enjoy the perks of expedited security screening at participating airports. So sit back, relax, and breeze through security checkpoints with ease!

Benefits of Having a Known Traveler Number

Holding a Known Traveler Number (KTN) comes with a range of benefits that can greatly enhance your travel experience. Let’s explore some of the advantages of having a KTN:

  • Expedited Security Screening: One of the primary benefits of having a KTN is the ability to go through expedited security screening. Instead of waiting in long lines, eligible travelers can use dedicated screening lanes, which are typically shorter and move more quickly. This means less time spent in line and more time saved for other activities.
  • Reduced Security Measures: When going through security with a KTN, you can enjoy the convenience of leaving your shoes, belts, and light jackets on, as well as keeping your laptops and compliant liquids in your bag. These perks not only save time but also reduce the hassle of removing and repacking personal items.
  • Less Stress and Anxiety: Traveling can be stressful, especially when dealing with long security lines and the fear of missing a flight. Having a KTN allows for a smoother and more streamlined security process, reducing stress and anxiety associated with travel. This enables you to start your journey in a more relaxed and enjoyable way.
  • Increase in Travel Efficiency: With expedited security screening, you can optimize your travel time and make the most of layovers or connections. Shorter security lines mean less time spent in airports, allowing you to spend valuable moments exploring the airport amenities, working on important tasks, or simply relaxing before your next flight.
  • Consistent Benefits Across Airlines: The benefits of having a KTN apply across various airlines participating in the TSA PreCheck program. This means that no matter which airline you fly with, you can still enjoy expedited security screening as long as your KTN is included in your reservation.
  • Cost-Effective in the Long Run: Although there is an initial application fee for TSA PreCheck or Global Entry, the long-term benefits outweigh the cost. Considering the time and convenience saved during each trip, having a KTN is a cost-effective investment for frequent travelers.

Having a Known Traveler Number not only enhances your individual travel experience but also contributes to the overall efficiency of the airport security process. By allowing trusted travelers to move through security more quickly, it helps to reduce congestion and improve the flow of passengers at airports.

It’s important to remember that while a KTN provides certain advantages, it does not guarantee expedited security screening in all circumstances. Random security checks or specific situations may still require additional screening measures. However, in most cases, having a Known Traveler Number significantly expedites the security process and makes traveling a more pleasant and hassle-free experience.

Understanding Redress Number

In addition to the Known Traveler Number, another important identification code for travelers is the Redress Number. The Redress Number is a unique identifier assigned to individuals who have experienced travel-related issues or encounters with mistaken identity during their previous trips.

Instances of mistaken identity can occur when a traveler’s name matches or closely resembles a name on a watchlist or database. This can lead to increased scrutiny, additional questioning, or even denial of boarding. The Redress Number serves as a means to resolve these issues and prevent future instances of mistaken identity.

Typically, individuals who have been incorrectly identified in the past or have faced challenges during the travel process can apply for a Redress Number. This number is then associated with their personal information in relevant airline systems, allowing for smoother travel experiences in the future.

The Redress Number provides a way for individuals to communicate their past travel challenges to relevant authorities and enables them to resolve any issues or misunderstandings proactively. It acts as a mechanism for clearing up any confusion related to identity verification and helps prevent unnecessary inconveniences during future travel.

It’s important to note that the Redress Number is not a guarantee of expedited security screening or any specific benefits like the Known Traveler Number. Its primary purpose is to rectify past travel issues and ensure smoother experiences for travelers going forward.

How to Obtain a Redress Number

If you have experienced travel-related issues or mistaken identity during previous trips, obtaining a Redress Number can be beneficial. Here’s a step-by-step guide on how to obtain a Redress Number:

  • Start by visiting the Department of Homeland Security’s Travel Redress Inquiry Program (TRIP) website. This is the official platform for submitting your request for a Redress Number.
  • On the TRIP website, you will find an online application form. Fill out the form with accurate personal information and provide as much detail as possible about your past travel challenges or encounters with mistaken identity.
  • Ensure that you have any relevant documentation or evidence to support your request. This may include boarding passes, travel itineraries, or identification documents that demonstrate the issues or inconveniences you have faced.
  • Submit the completed application form along with any supporting documentation through the TRIP website. Double-check that all the information provided is correct and up to date.
  • Once your application is submitted, the Department of Homeland Security will review your case and conduct a thorough investigation. This may involve cross-referencing your information with various watchlists and databases to ensure accuracy.
  • If your request is approved, you will receive a Redress Number. This unique identifier will be associated with your personal information in relevant airline systems, helping to prevent any future instances of mistaken identity or travel-related issues.
  • Ensure that you keep a record of your Redress Number in a secure location. You will need to provide this number when making flight reservations or contacting airlines regarding any travel-related concerns.
  • Once you have your Redress Number, be sure to include it in your travel reservations to ensure a smoother travel experience. The airline will use this number to identify you and provide any necessary adjustments or accommodations.

It’s important to keep in mind that obtaining a Redress Number does not guarantee a completely seamless travel experience, as random security checks or other factors can still affect the screening process. However, having a Redress Number can help resolve past travel challenges and minimize the chances of future issues related to mistaken identity.

By following the steps outlined above and providing accurate information and documentation, you can initiate the process of obtaining a Redress Number and enjoy a smoother, more hassle-free travel experience in the future.

Importance of Having a Redress Number

Holding a Redress Number is of great importance for individuals who have faced travel-related issues or mistaken identity during their previous trips. Let’s explore the significance of having a Redress Number:

  • Resolution of Past Travel Challenges: A Redress Number serves as a means to address and rectify past travel difficulties. By providing accurate and detailed information about previous encounters with mistaken identity or travel-related issues, individuals can ensure that their concerns are heard and resolved.
  • Prevention of Future Issues: The Redress Number is associated with an individual’s personal information in relevant airline systems. This helps to prevent future instances of mistaken identity, as airport security and airline personnel have access to this designated number for verification and identification purposes.
  • Smoother Travel Experiences: Having a Redress Number can significantly enhance the travel experience by reducing unnecessary scrutiny and delays. With the inclusion of the Redress Number in travel reservations, airports and airlines are better equipped to recognize and address any potential mix-ups or misunderstandings quickly, leading to a smoother journey for the traveler.
  • Improved Security Measures: The process of obtaining a Redress Number involves a comprehensive review of the individual’s information and cross-referencing with watchlists and databases. This ensures that security measures are applied more accurately, focusing on genuine threats and minimizing the inconvenience to innocent travelers.
  • Increased Peace of Mind: Traveling can be stressful, and the fear of encountering travel problems or delays can add to that stress. By having a Redress Number, travelers can have more peace of mind, knowing that they have taken proactive steps to address any past issues and reduce the likelihood of future travel-related challenges.

While the Redress Number does not provide expedited screening or specific benefits like the Known Traveler Number, its importance lies in resolving past challenges and ensuring a smoother travel experience in the future. By communicating past issues and providing relevant information, individuals can help airport security personnel and airline staff to better understand their unique circumstances and minimize any potential disruptions during travel.

Remember to include your Redress Number when making travel reservations and contact the airline directly if you encounter any issues during the booking process or at the airport. By doing so, you can ensure that the airline is aware of your Redress Number and can appropriately handle any situations that may arise.

Having a Redress Number is an invaluable tool for individuals who have faced travel-related challenges. It provides a means for resolving past issues, preventing future ones, and contributing to a more seamless and stress-free travel experience.

In conclusion, the Known Traveler Number (KTN) and the Redress Number are two essential identification codes that can greatly enhance the travel experience for individuals. The KTN allows for expedited security screening, reducing wait times and providing conveniences such as keeping shoes, belts, and light jackets on, as well as keeping laptops and compliant liquids in carry-on bags. Obtaining a KTN involves applying for trusted traveler programs like TSA PreCheck or Global Entry and undergoing a thorough background check.

One woman asserted that the Transportation Security Administration’s (TSA) secondary checks are not always random and took to TikTok to share tips on how to avoid getting stopped.

In a viral video that has garnered over 364,100 views and more than 13,700 likes, TikToker Megan (@megansbubble) provided advice for individuals who frequently undergo searches by the TSA.

Holding up a flight boarding pass, she pointed out the “SSSS” on it, which she says indicates she is likely to face additional screening. According to Travel + Leisure , the four capitalized letters on a boarding pass stand for Secondary Security Screening Selection. However, per the publication, there is no published information about who gets selected for the additional security check.

“They are not random because you will see this on your tickets if you are likely someone like me,” she said.

She added that despite her efforts to apply for global entry and TSA PreCheck, follow airport regulations regarding metals and liquids, and avoid wearing metal to airports, she continued to experience delays at security. She believes that passengers who often get stopped at airport security points have likely been “flagged.”

“I finally got fed up with this because I was to the point where I had terrible anxiety going to airports,” she said. “Because I would have TSA people touching me in my hair, feeling up on my body.”

Eventually, she sought a solution.

“After being harassed for years, I decided that I needed to do something about this,” she explained.

Frustrated by years of harassment and anxiety, she said she eventually turned to filing complaints on the TSA’s website. The Department of Homeland Security has a Traveler Redress Inquiry Program that can be helpful when travelers want their names removed from “watchlists” if they are not, in fact, a security threat.

“They will research it, and they will take a look and see if you have been being stopped where you shouldn’t be,” she said.

For the agency to do so, the passenger may have to offer up flight information, she added.

“If they agree that you are being stopped wrongfully, you will get a nice letter from the government that gives you a redress number,” she continued.

Upon receiving a redress number, she said she used it when booking flights to signal her past wrongful stops.

Megan said the redress number worked for some time. However, she believes that after marrying her husband, he was also targeted for additional checks by the TSA. So, the couple was forced to file a complaint to also get him a redress number.

“Within 48 hours, they said he was flagged too and gave him a redress number,” she said.

Viewers in the comments section shared similar experiences, claiming that the checks are not random.

“When TSA precheck used to be ‘random’ on your ticket, I got it every single time,” user Karen said. “Dad has security clearance… It’s not random.”

“Mom didn’t fly that often, but when she did she got pulled every time,” user Suz said. “Even her ashes where bomb checked. My dad, never and not even his ashes … TY.”

“I used to get stopped every single time,” user Chuck Tangler wrote. “It flagged my pelvic region I’ll die on the hill it was my Nuva Ring birth control. TSA pre check saved me.”

The Daily Dot reached out to Megan and TSA via email for more information.

How you should think about those Google Flights pollution numbers

travel number or redress number

Flight booking platforms are giving customers a new number to think about when they buy a plane ticket: the expected greenhouse gas emissions of their trip.

If you’ve searched for plane tickets on Google Flights in the past two years, you’ve probably seen a little green number that compares each route’s climate impact. Google began predicting flight emissions in 2022, using data about flight schedules, airplane models and how full a flight is expected to be to come up with an estimate for each passenger’s carbon footprint.

Lately, other platforms, including Expedia and Booking.com, have started using the same algorithm, called the Travel Impact Model (TIM) , to tell customers whether their itinerary emits more or less carbon than usual.

But what, exactly, are these little green numbers — and how should an eco-conscious traveler take them into account when picking out flights? We asked the group that manages the model and a pair of economists what you should do with your emissions estimate.

Decoding the Travel Impact Model

To come up with an emissions estimate, the Travel Impact Model estimates how much fuel your plane will burn along its route, and then it estimates how much of those emissions you’re responsible for compared with other passengers.

Say you’re flying from Zurich to San Francisco on a Boeing 787-9.

In case you were wondering...

Google’s model is one of the first to publicly estimate emissions for different flight options, according to Dan Rutherford, who heads an outside advisory board that checks Google’s work and suggests tweaks to make the model more accurate. “This is an effort to get data into the hands of consumers so they choose a less emitting flight,” he said.

On average, customers could cut their flight emissions about 20 percent if they picked the least polluting itinerary, according to a 2021 report from the nonprofit International Council on Clean Transportation (ICCT) based on an earlier emissions model that also compared available flights. They wouldn’t even have to pay much more in most cases: Greener flights also tend to be cheaper because they burn less fuel, according to the report.

What does a kilo of carbon cost?

So how should you weigh the benefit of lower emissions against other goodies, like picking the most convenient departure time or racking up miles on your favorite airline? One trick is to think about the “social cost of carbon,” an economic estimate of how much damage every additional bit of greenhouse gas pollution will do to the world.

The latest estimate , adopted by the Biden administration , puts the social cost of carbon at about $190 per metric ton — or about 19 cents per kilo. The flight from our Zurich to San Francisco example would do about $114 worth of climate damage if you flew in economy, or $456 in business class.

So if you want to consider the climate impact of your flight options, you could add the cost of carbon emissions onto the price of your plane ticket. Then compare your flight choices — departure times, layovers, airline points, etc. — with this new carbon-included price in mind and pick the option that seems like the best deal.

But you should take this carbon price with a grain of salt. It’s hard to put a dollar figure on climate damage, and economists disagree on the final number. To come up with an estimate, scientists model how much each additional ton of CO2 will heat the earth and contribute to sea level rise, droughts, wildfires and other calamities. Then economists determine how much those disasters will cost in terms of property damage, crop failures, hospital visits and so on.

“There are many, many links on this chain, and there’s a lot of uncertainty at each link,” said Lawrence Goulder, a Stanford University economist who studies climate change.

A simple rule of thumb

If you don’t want to deal with all that math, you can make your choice much simpler, according to Kenneth Gillingham, an economist at the Yale School of the Environment. “If people look at two flights and say, ‘The timing is the same, the cost is the same, why not grab the lower emissions one?’ Then that’s helpful,” he said.

Rutherford suggests following the ICCT’s informal rule on air travel: If you’re buying a plane ticket, consider at least three options and compare them on cost, convenience and emissions before making your choice. You don’t always have to pick the greenest flight — but if you make an effort to think about emissions, you’ll tend to make planet-friendlier choices.

“It’s about making informed decisions, not perfect decisions,” Rutherford said.

Of course, you could choose the greenest option of all, which is not to fly. But that’s not always practical in the United States, which lacks high-speed rail lines or other good alternatives to air travel. So if you’re going to fly, you might as well pick the least-emitting flight you can.

“You’re helping the world, it’s not affecting you very much, and it’s an easy thing to do,” Gillingham said. “We need more of these easy things to do in our lives.”

Highlights From SpaceX’s Starship Test Flight

The powerful rocket, a version of which will carry astronauts to the moon for NASA, launched for the third time on Thursday morning. It achieved a number of milestones before losing contact with the ground.

Here’s what happened during the third test flight of the most powerful rocket ever built.

Spacex launches starship for third time, the rocket, a version of which will eventually carry nasa astronauts to the moon, traveled almost halfway around the earth before it was lost as it re-entered the atmosphere..

“Five, four, three, two, three, one.” “This point, we’ve already passed through Max-Q, maximum dynamic pressure. And passing supersonic, so we’re now moving faster than the speed of sound. Getting those on-board views from the ship cameras. Boosters now making its way back, seeing six engines ignited on ship. Kate, we got a Starship on its way to space and a booster on the way back to the Gulf.” “Oh, man. I need a moment to pick my jaw up from the floor because these views are just stunning.”

The third try turned out to be closer to the charm for Elon Musk and SpaceX, as his company’s mammoth Starship rocket launched on Thursday and traveled about halfway around the Earth before it was lost as it re-entered the atmosphere.

The test flight achieved several key milestones in the development of the vehicle, which could alter the future of space transportation and help NASA return astronauts to the moon.

This particular flight was not, by design, intended to make it all the way around the Earth. At 8:25 a.m. Central time, Starship — the biggest and most powerful rocket ever to fly — lifted off from the coast of South Texas. The ascent was smooth, with the upper Starship stage reaching orbital velocities. About 45 minutes after launch, it started re-entering the atmosphere, heading toward a belly-flop splashdown in the Indian Ocean.

Live video, conveyed in near real-time via SpaceX’s Starlink satellites , showed red-hot gases heating the underside of the vehicle. Then, 49 minutes after launch, communications with Starship ended, and SpaceX later said the vehicle had not survived the re-entry, presumably disintegrating and falling into the ocean.

Even so, Bill Nelson, the administrator of NASA, congratulated SpaceX on what he called a “successful test flight” of the system his agency is counting on for some of its Artemis lunar missions.

SpaceX aims to make both the vehicle’s lower rocket booster and the upper spacecraft stage capable of flying over and over again — a stark contrast to the single-launch throwaway rockets that have been used for most of the space age.

That reusability gives SpaceX the potential to drive down the cost of lofting satellites and telescopes, as well as people and the things they need to live in space.

Completing most of the short jaunt was a reassuring validation that the rocket’s design appears to be sound. Not only is Starship crucial for NASA’s lunar plans, it is the key to Mr. Musk’s pipe dream of sending people to live on Mars.

For Mr. Musk, the success also harks back to his earlier reputation as a technological visionary who led breakthrough advances at Tesla and SpaceX, a contrast with his troubled purchase of Twitter and the polarizing social media quagmire that has followed since he transformed the platform and renamed it X. Even as SpaceX launched its next-generation rocket, the social media company was dueling with Don Lemon , a former CNN anchor who was sharing clips from a combative interview with Mr. Musk.

SpaceX still needs to pull off a series of formidable rocketry firsts before Starship is ready to head to the moon and beyond. Earlier this week, Mr. Musk said he hoped for at least six more Starship flights this year, during which some of those experiments may occur.

But if it achieves them all, the company could again revolutionize the space transportation business and leave competitors far behind.

Phil Larson, a White House space adviser during the Obama administration who also previously worked on communication efforts at SpaceX, said Starship’s size and reusability had “massive potential to change the game in transportation to orbit. And it could enable whole new classes of missions.”

NASA is counting on Starship to serve as the lunar lander for Artemis III, a mission that will take astronauts to the surface of the moon for the first time in more than 50 years. That journey is currently scheduled for late 2026 but seems likely to slide to 2027 or later.

The third flight was a marked improvement from the first two launch attempts.

Last April, Starship made it off the launchpad, but a cascade of engine failures and fires in the booster led to the rocket’s destruction 24 miles above the Gulf of Mexico.

In November, the second Starship launch traveled much farther. All 33 engines in the Super Heavy booster worked properly during ascent, and after a successful separation, the upper Starship stage nearly made it to orbital velocities. However, both stages ended up exploding.

Nonetheless, Mr. Musk hailed both test flights as successes, as they provided data that helped engineers improve the design.

Thursday’s launch — which coincided with the 22nd anniversary of the founding of SpaceX — occurred 85 minutes into a 110-minute launch window. The 33 engines in the booster ignited at the launch site outside Brownsville, Texas, and lifted the rocket, which was as tall as a 40-story building, into the morning sky.

Most of the flight proceeded smoothly, and a number of test objectives were achieved during the flight, like opening and closing the spacecraft’s payload doors, which will be needed to deliver cargo in the future.

SpaceX did not attempt to recover the booster this time, but did have it perform engine burns that will be needed to return to the launch site. However, the final landing burn for the booster, conducted over the Gulf of Mexico, did not fully succeed — an area that SpaceX will attempt to fix for future flights.

SpaceX said the Super Heavy disintegrated at an altitude of about 1,500 feet.

SpaceX engineers will also have to figure out why Starship did not survive re-entry and make fixes to the design of the vehicle.

Even with the partial success of Thursday’s flight, Starship is far from ready to go to Mars, or even the moon. Because of Mr. Musk’s ambitions for Mars, Starship is much larger and much more complicated than what NASA needs for its Artemis moon landings. For Artemis III, two astronauts are to spend about a week in the South Pole region of the moon.

“He had the low price,” Daniel Dumbacher, the executive director of the American Institute of Aeronautics and Astronautics and a former high-level official at NASA, said of Mr. Musk, “and NASA chose to take the risk associated with that configuration hoping that it would work out. And we’ll see if that turns out to be true.”

To leave Earth’s orbit, Starship must have its propellant tanks refilled with liquid methane and liquid oxygen. That will require a complex choreography of additional Starship launches to take the propellants to orbit.

“This is a complicated, complicated problem, and there’s a lot that has to get sorted out, and a lot that has to work right,” Mr. Dumbacher said.

Thursday’s flight included an early test of that technology, moving liquid oxygen from one tank to another within Starship.

Mr. Dumbacher does not expect Starship to be ready by September 2026, the launch date NASA currently has for Artemis III, although he would not predict how much of a delay there might be. “I’m not going to give you a guess because there is way too much work, way too many problems to solve,” he said.

A rare sight: Starship’s bright orange glow as it re-entered Earth’s atmosphere.

Just past the 45-minute mark of the Starship vehicle’s journey through space on Thursday, something eerie happened. As it drifted high above Earth’s oceans and clouds, the spacecraft’s silvery exterior was overtaken by a brilliant and fiery orange glow.

Starship re-entering Earth's atmosphere. Views through the plasma pic.twitter.com/HEQX4eEHWH — SpaceX (@SpaceX) March 14, 2024

When a spacecraft re-enters the atmosphere, the air beneath it gets hot — hot enough that it turns into a plasma of charged particles as electrons are stripped away from the air molecules. The charged particles create picturesque glows, like neon signs.

But seeing this happen in nearly real-time during a spaceflight is uncommon. That plasma disrupts radio signals, cutting off communication.

Such blackouts happen, for instance, when SpaceX’s Crew Dragon capsule returns to Earth from the International Space Station with its complement of four astronauts. Mission controllers must wait with bated breath to be reassured that the spacecraft’s heat shield has held up and protected the crew during atmospheric re-entry.

Until Starship succumbed to the intense forces of re-entry on Thursday, SpaceX used its Starlink internet satellites to relay the live video feed. The Starlink satellites are in higher orbits, and sending signals upward — away from the plasma — is easier than trying to communicate through it to antennas on the ground.

But Starship wasn’t the only spacecraft in recent weeks to give us a view of plasma heating. Varda Space, a startup that is developing technology for manufacturing in orbit, had cameras on a capsule it landed on Earth on Feb. 21. Before it parachuted to the ground, its Winnebago capsule recorded a day-glow re-entry. The company retrieved the video recording from the capsule and shared it online:

Jeff Bezos’s rocket company could race SpaceX to the moon.

Which billionaire space company will get to the moon first: Elon Musk’s SpaceX or Jeff Bezos’ Blue Origin?

At first glance, SpaceX seems to have a huge head start. It is about to launch the third test flight of Starship. A variation of Starship is scheduled to take NASA astronauts to the surface of the moon as soon as September 2026.

By contrast, Blue Origin has yet to launch anything into orbit, and its contract with NASA for a lunar lander for astronauts is for a mission that is launching in 2030.

But Blue Origin might still get there first. SpaceX faces major challenges with Starship, which is as tall as 16-story building, while Blue Origin plans to send a smaller cargo lander to the moon by the end of next year.

“This lander, we’re expecting to land on the moon between 12 and 16 months from today,” John Couluris, senior vice president of lunar permanence at Blue Origin, said during a n interview on the CBS News program “60 Minutes” this month.

The first launch of the Mark 1 version of the Blue Moon lander is what Blue Origin calls a “pathfinder” to test technologies like the BE-7 engine, the flight computers, avionics and power systems — the same systems that will be used in the much larger Mark 2 lander that will take astronauts to the moon’s surface.

The Mark 1 lander can carry up to three tons of cargo to the lunar surface, but will be small enough to fit inside one of Blue Origin’s New Glenn rockets . New Glenn has yet to fly, but the company says its debut journey will occur later this year.

After Blue Moon Mark 1 is launched into an orbit about 125 miles above Earth’s surface, the lander’s BE-7 engine will propel it toward the moon, slowing it down to enter orbit around the moon and then guiding it to the landing on the surface.

The smaller size means that the Mark 1 lander, unlike Starship, will not need to be refueled before leaving Earth orbit. Demonstrating that refueling technology in orbit will be a key test to validate Starship’s design. Refueling will also be needed for the Blue Moon Mark 2 lander.

Mr. Musk and Mr. Bezos have already been beaten to the moon by another billionaire, Kam Ghaffarian , one of the founders of Intuitive Machines, which put a small robotic lander named Odysseus near the lunar south pole in February . That was the first private spacecraft to successfully make it to the moon’s surface in one piece (although its journey had some hiccups ).

As with every American rocket mishap, the Federal Aviation Administration will open an investigation to review what went wrong and what SpaceX needs to do to correct it. But if, as Elon Musk says, there are at least six more Starship flights this year, SpaceX will have opportunities to complete a full test flight.

Starship's third flight went very far, but like its first two flights, it was not a complete success. The landing burn for the Super Heavy booster stage of the rocket — the aim was to “land” it in the Gulf of Mexico — was not fully successful, and the Starship craft did not survive re-entry. But it was marked significant progress, because none of the problems from the earlier flights recurred, and SpaceX engineers now have data to tackle the new problems.

Michael Roston

On the social media site X, Bill Nelson, the administrator of NASA, congratulated SpaceX on what he called a “successful test flight” of Starship. The agency is counting on Starship to land astronauts on the moon’s surface as part of the Artemis III mission. Another vehicle, the Orion capsule, is to be used to bring those astronauts back to Earth.

SpaceX says Starship did not survive re-entry, but it achieved several key milestones during the flight. That marks significant progress since the second test flight. Elon Musk has said he hopes there will be a half-dozen Starship flights this year.

SpaceX says a dual loss of communication, both through its own Starlink satellites and other forms spacecraft communications with Earth, suggest that Starship did not survive re-entry. They’re still listening to see if radio contact resumes.

Video is gone. Telemetry is also stuck at a speed 25,707 kilometers per hour and an altitude of 65 kilometers. The reason is not clear.

Starship already has private customers booked for deep space trips.

Starship has not yet done a full orbit of the Earth, but SpaceX already has three private astronaut missions on its manifest for the spacecraft.

The first flight with astronauts aboard will be led by Jared Isaacman who previously bought an orbital trip on a Falcon 9 rocket that was known as Inspiration4 .

Then two other Starship flights will travel around the moon and back, one led by Yusaku Maezawa , a Japanese entrepreneur, and the other by Dennis Tito, who was the first private individual to buy a trip to the International Space Station in 2001.

Back in 2018 when Mr. Maezawa signed up for the lunar flyby, Mr. Musk said Starship would be ready by 2023.

Mr. Maezawa later called the mission ‘dearMoon,’ inviting people to apply for a seat on the trip. Last week, he acknowledged it was not going to happen this year.

“We were planning for our lunar orbital mission ‘dearMoon’ to take place in 2023, but seems like it will take a little longer,” he wrote on the social network X. “We’re not sure when the flight will be, but we will give you all an update once we know more.”

SpaceX is apparently also planning uncrewed cargo flights to the surface of the moon with Starship.

In March last year, a small start-up company, Astrolab, announced that it was sending a Jeep Wrangler-size rover to surface in the south polar region of the moon , and the ride would be a cargo Starship flight that would take it there.

SpaceX did not confirm the news.

This appears to be part of the expanding potential market for Starship. SpaceX also plans to use the rocket for launching its second generation of Starlink internet communications satellites .

Starship is re-entering Earth's atmosphere. We’re seeing the heating on the flaps, with video being transmitted to the ground through SpaceX's Starlink satellites. The view is incredible. Usually the plasma disrupts radio transmissions.

SpaceX skipped the restart of one of the Raptor engines on the upper stage of Starship. It did conduct the propellant transfer test and the opening and closing of the payload door, which means the flight achieved some of its experimental objectives during its coast around the Earth, but not others. Next stop: Re-entry through the atmosphere and a hard bellyflop in the Indian Ocean.

The music on the livestream is more old-fashioned than the ambient beats we’re used to during SpaceX video feeds. But there’s nothing old-fashioned about the views in space from the rocket, which are unreal, but have not always been visible as its connection to the ground comes and goes.

During this period of the flight, Starship is scheduled to perform several tests. The first, opening the payload door, is complete. It will also move several tons of liquid oxygen between two tanks within Starship. That’s a preliminary test for future in-orbit refueling between two Starships, which is critical for sending the vehicle to the moon. Finally, Starship will try to restart one of its Raptor engines in the vacuum of space, something it has not done before.

The payload door of the upper Starship rocket stage is now open. That’s how a future Starship will deploy Starlink satellites, and demonstrating that it works was one of the objectives of today's flight.

The engines on the upper-stage of the rocket successfully completed their burn. Starship is now coasting in space, on a trajectory that will re-enter the atmosphere over the Indian Ocean.

We were watching the booster attempting to land in the Gulf of Mexico. But the camera feed cut off, and we're not sure what actually happened. The upper stage Starship is still continuing on its trajectory toward the Indian Ocean.

The Super Heavy booster stage of the rocket appears to be headed back to Earth. During the last attempt, the booster exploded at this point, so it looks like SpaceX has fixed that issue.

The large Super Heavy booster stage has separated from the Starship upper stage, which is on its way to space. The flight is looking good.

All 33 Raptor engines in the booster are working fine. So far everything looks good.

Less than 2 minutes until liftoff. Propellant tanks are full, and wind will not prevent an on-time liftoff.

Starship is less than 10 minutes away from its third launch. The countdown is going smoothly.

What will happen during Starship’s third test flight.

For its third test flight, Starship aims to fly part of the way around the Earth, starting from SpaceX’s launch site in Boca Chica Village, Texas, and splashing down in the Indian Ocean.

The earlier test flights — both of which ended in explosions — aimed to come down in waters off Hawaii. SpaceX said it had set the new flight path to allow for safe testing of things it hadn’t done before with the Starship vehicle.

The journey will start at the site that SpaceX calls Starbase, which is a few miles north of where Texas and Mexico meet along the Gulf of Mexico. The rocket, nearly 400 feet tall, will be mounted next to a launch tower that is about 480 feet tall. It will be filled with methane and liquid oxygen propellants during the hours before liftoff.

Three seconds before launch, computers will begin to ignite the 33 engines in the Super Heavy rocket booster beneath Starship.

Starship and Super Heavy will begin their ascent over the Gulf. At 52 seconds into the flight, SpaceX says, the vehicle will experience the heaviest atmospheric stress of its trip, a moment flight engineers call max-q.

If the stainless steel spacecraft survives that stress, the next key moment will occur 2 minutes and 42 seconds into flight, when most of the Super Heavy booster’s engines power down. Seconds later, the upper Starship vehicle will begin “hot-staging,” or lighting up its engines before separating from Super Heavy.

Super Heavy’s journey will end about seven minutes after launch. SpaceX would typically aim to return the massive rocket booster to the launch site for a vertical landing. But for the test flight, the spent Super Heavy will perform a series of maneuvers before firing its engines one last time to slow its descent into the Gulf of Mexico.

As Super Heavy is descending, Starship will be gaining altitude. About eight and a half minutes into its flight, its engines will switch off. It will then begin coasting around the Earth.

While floating through space, Starship will attempt several things that the spacecraft has never done. Nearly 12 minutes into the flight, it will open a door that in the future could deploy satellites and other cargo into space. About 12 minutes later, it will transfer propellants from one tank to another while in space, a technique needed for future journeys to the moon and beyond. Then, 40 minutes into the flight, Starship will relight one if its engines while in space.

If the spacecraft makes it through those experiments, the conclusion of Starship’s journey will start at about the 49-minute mark. The spacecraft is set to pivot horizontally into a belly-flop to re-enter Earth’s atmosphere. If it survives the extreme temperatures, Starship will splash down 64 minutes after it left Texas. The company has said in the past that it expects the belly-flop ocean landing to end in an explosion .

After SpaceX completes its testing campaign, future Starship flights will return to the Texas Starbase site after they complete their missions in orbit. SpaceX is also building a launch tower for Starship at Kennedy Space Center in Florida, where flights could one day launch and land, including the Artemis III mission that NASA plans to use to return American astronauts to the moon’s surface.

SpaceX has started the company’s official live video stream from Texas, a sign that it is serious about igniting the rocket in about 20 minutes. You can watch it in the video player embedded above.

What went right and wrong during the 2nd Starship test flight.

The second test flight of Starship in November got a lot higher and faster than the first attempt seven months earlier.

During the first launch outside Brownsville, Texas, in April last year, things went wrong from the start — the exhaust of the engines of the Super Heavy booster excavated a hole beneath the launchpad, sending pieces of concrete flying up to three-quarters of a mile away and a plume of dust drifting 6.5 miles, blanketing the nearby town of Port Isabel. Several of the booster engines failed, and the upper stage never separated from the booster.

Instead, the rocket started making loop-de-loops before the flight termination system destroyed it.

During the second test flight , all 33 of the booster engines worked during ascent. A water deluge system protected the launchpad. The upper Starship stage separated from the booster and then made it most of the way to orbital velocity. However, the journeys of both the booster and the upper Starship stage still ended in explosions.

For the booster, as it dropped away from the upper stage, 13 of the 33 engines fired again to guide it toward the landing location. Although this particular booster was not going to be recovered, SpaceX wanted to test the re-entry techniques that are similar to what it currently uses for its smaller Falcon 9 rockets. However, something went wrong. Several engines shut down and then one blew up, causing the destruction of the booster.

In an update posted on the company’s website on Feb. 26 , SpaceX said the most likely cause of the booster failure was a blockage of a filter where liquid oxygen flowed to the engines. The company said it had made design changes to prevent that from happening again.

The upper stage continued upward for seven minutes after stage separation. This was itself an achievement because the company completed a step called hot-staging, during which the upper-stage engines ignite before the stage detaches from the Super Heavy booster.

Because the spacecraft was empty, extra liquid oxygen was loaded to simulate the weight of a future payload it could carry to orbit. But when the extra oxygen was dumped, a fire started, disrupting communication between the spacecraft’s flight computers. The computers shut down the engines and then set off the flight termination system, destroying the spacecraft.

The upper Starship stage reached an altitude of about 90 miles and a speed of about 15,000 miles per hour. For a spacecraft to reach orbit, it needs to accelerate to about 17,000 miles per hour.

Frost lines have appeared on Starship and the Super Heavy booster as methane and liquid oxygen flow into the rocket’s tanks.

It’s sunrise in Cameron County, Texas, but weather reports show cloudy conditions persist. We’ll see if weather is going to keep Starship on the beach, but SpaceX says it has started loading propellants into the rocket.

Launch time is now 9:25 a.m. Eastern. SpaceX says winds are still a concern that could cause a liftoff to be called off, but it will go ahead with loading of propellants in the rocket.

SpaceX pushed the launch time back a little more, to 9:10 a.m. Eastern. They have until 9:50 to try today.

SpaceX has just announced the new target launch time is 9:02 a.m. Eastern, and the company said on X that it is clearing some boats from a safety zone in the Gulf of Mexico. Cameras from a number of space enthusiast websites like NASASpaceflight that are pointing at the rocket show there is still no frost on its side, so the loading of ultracold methane and liquid oxygen propellants has not yet begun.

As SpaceX prepares for its third flight of Starship, other space efforts have experienced difficulties this week. On Wednesday, Kairos, a rocket from a Japanese startup called Space One, exploded moments into its first launch attempt. And Xinhua, a Chinese state news agency, said on Thursday that two Chinese satellites were lost after a rocket failed to reach the planned orbit.

In a posting on the social media site X, SpaceX says that it is aiming for launch at 8:30 a.m. Eastern time, or 30 minutes into the 110-minute launch window. There is a 70 percent chance of favorable weather. There have been concerns of high winds, especially at higher altitudes.

What is Starship?

For Elon Musk, Starship is really a Mars ship. He envisions a fleet of Starships carrying settlers to the red planet in the coming years.

And for that eventual purpose, Starship, under development by Mr. Musk’s SpaceX rocket company , has to be big. Stacked on top of what SpaceX calls a Super Heavy booster, the Starship rocket system will be, by pretty much every measure, the biggest and most powerful ever.

It is the tallest rocket ever built — 397 feet tall, or about 90 feet taller than the Statue of Liberty including the pedestal.

And it has the most engines ever in a rocket booster: The Super Heavy has 33 of SpaceX’s powerful Raptor engines sticking out of its bottom. As those engines lift Starship off the launchpad in South Texas, they will generate 16 million pounds of thrust at full throttle.

NASA’s new Space Launch System rocket , which made its first flight in November 2022, holds the current record for the maximum thrust of a rocket: 8.8 million pounds. The maximum thrust of the Saturn V rocket that took NASA astronauts to the moon during the Apollo program was relatively paltry: 7.6 million pounds.

An even more transformative feature of Starship is that it is designed to be entirely reusable. The Super Heavy booster is to land much like those for SpaceX’s smaller Falcon 9 rockets, and Starship will be able to return from space belly-flopping through the atmosphere like a sky diver before pivoting to a vertical position for landing.

That means all of the really expensive pieces — like the 33 Raptor engines in the Super Heavy booster and six additional Raptors in Starship itself — will be used over and over instead of thrown away into the ocean after one flight.

That has the potential to cut the cost of sending payloads into orbit — to less than $10 million to take 100 tons to space, Mr. Musk has predicted.

Starship and Super Heavy are shiny because SpaceX made them out of stainless steel, which is cheaper than using other materials like carbon composites. But one side of Starship is coated in black tiles to protect the spacecraft from the extreme heat that it will encounter if it gets far enough in its flight to re-enter the atmosphere.

Here is what to know about Thursday’s SpaceX test flight.

The third try was closer to the charm for Elon Musk and SpaceX, as the company’s flight test of the mammoth Starship rocket launched on Thursday and traveled almost halfway around the Earth before it was lost as it re-entered the atmosphere.

The flight achieved some key milestones in the development of the vehicle, which could alter the future of space transportation and help NASA return astronauts to the moon.

This particular flight did not, by design, make it all the way around the Earth. At 9:25 a.m. Eastern time, Starship, the biggest and most powerful rocket ever to fly, lifted off from the coast of South Texas. About 45 minutes later it started its re-entry, but communications were lost a few minutes after that. The company said the rocket was lost before attempting to splash down in the Indian Ocean, a sign that more work needs to be completed on the vehicle.

That reusability gives SpaceX the potential to drive down the cost of lofting satellites and space telescopes, as well as people and the things they need to live in space.

Here’s what else to know:

Thursday’s flight demonstrated new capabilities for Starship. In addition to reaching orbital speeds, the Starship vehicle opened and closed its payload door and managed to move several tons of liquid oxygen between two tanks within the rocket, a key test needed for future missions.

The Starship system consists of two stages — the Super Heavy rocket booster and the upper-stage spacecraft, which is also called Starship. The company intends both to be fully reusable in the future. Read more about Starship .

Thursday’s launch was the third of Starship. Here’s a recap of what happened last time .

Wrongful Post Office convictions to be quashed through landmark legislation: 13 March 2024

Hundreds of innocent sub-postmasters wrongly convicted as a result of the Horizon scandal will have convictions quashed following landmark legislation introduced today [Wednesday 13 March].

travel number or redress number

  • Government introduces new legislation to automatically quash convictions relating to the Horizon Scandal
  • £75,000 redress payment extended to ensure swift and fairer redress for postmasters who weren’t convicted but suffered as a result of the scandal
  • Comes as £179 million paid to around 2,800 victims so far with further measures introduced to accelerate payments

Hundreds of innocent sub-postmasters wrongly convicted as a result of the Horizon scandal will have convictions quashed following landmark legislation introduced today [Wednesday 13 March].  

This blanket exoneration, delivered through the Post Office (Horizon System) Offences Bill, will quash convictions brought about by erroneous Horizon evidence, clearing the names of many people who have had their lives ruined.   

Affected sub-postmasters will receive an interim payment with the option of immediately taking a fixed and final offer of £600,000, so that they can finally begin to rebuild their lives. 

Under the proposed Bill, convictions will be automatically quashed if they meet the following criteria: 

  • Were prosecuted by the Post Office or Crown Prosecution Service (CPS).
  • Were for offences carried out in connection with Post Office business between 1996 and 2018. 
  • Were for relevant offences such as theft, fraud and false accounting.
  • Were against sub-postmasters, their employees, officers, family members or direct employees of the Post Office working in a Post Office that used the Horizon system software. 

Prime Minister, Rishi Sunak MP, said:  

I want to pay tribute to all the postmasters who have shown such courage and perseverance in their fierce campaign for justice, and to those who tragically won’t see the justice they deserve. 
While I know that nothing can make up for what they’ve been through, today’s legislation marks an important step forward in finally clearing their names. 
We owe it to the victims of this scandal who have had their lives and livelihoods callously torn apart, to deliver the justice they’ve fought so long and hard for, and to ensure nothing like this ever happens again.” 

The Government has also confirmed it will bring forward enhanced financial redress for postmasters who were not convicted, or part of legal action against the Post Office, but who still suffered considerably due to Horizon failures. These individuals, also known as the Horizon Shortfall Scheme cohort, will have the option to receive a fixed sum payment of £75,000.  

Those who have already settled for less money will have their redress topped up to this level bringing them in line with the successful approach taken for members of the Group Litigation Order group of postmasters. 

The Department for Business and Trade will now be responsible for delivering the new Horizon Convictions Redress Scheme which will make redress payments to those who have had their convictions quashed by today’s legislation. The aim is to have the scheme open for applications as soon as possible once the legislation has been passed.  

Postal Affairs Minister, Kevin Hollinrake MP, said: 

Postmasters have been fighting for justice for years, and I hope the introduction of today’s legislation is the light at the end of the tunnel they have been waiting for. 
It is only right that postmasters have access to swift and fair compensation which is why those with overturned convictions have the option of immediately taking a fixed and final offer of £600,000 and why we are changing the rules for those in the Horizon Shortfall Scheme, so they are entitled to a £75,000 fixed sum award, bypassing the assessment process.  
For those who don’t choose this option, their claims can be assessed as part of the usual scheme process, in which there is no limit to compensation.” 

Business Secretary, Kemi Badenoch MP, said:  

It is absolutely right that we sweep away the convictions wrongly given to postmasters on the basis of bad evidence, and it is a disgrace that they were ever pursued by the Post Office.
This is just the latest step in the road to delivering the justice the postmasters deserve. Since the High Court ruling in December 2019, this government has established a Statutory Inquiry, paid millions in compensation, supportedlegal fees for victims and announced plans to overturn convictions. 
That is government in action, and we won’t rest until every victim receives the compensation they are entitled to.

Lord Chancellor and Secretary of State for Justice, Alex Chalk MP, said:  

Today’s legislation is a watershed moment for sub-postmasters who have campaigned tirelessly for justice in the wake of the Horizon scandal.  
These are exceptional circumstances which require an exceptional response to ensure those who were wrongly convicted can not only clear their names but be fairly and swiftly compensated.”  

The Horizon IT Scandal is one of the greatest miscarriages of justice in our nation’s history which dates back to the 1990s, and this Government has gripped it to right the wrongs of the past. But this doesn’t come from a standing start – the Government has spent years getting us to this point. 

In February 2020, the Government launched the independent Post Office Horizon IT Inquiry to get to the bottom of what happened and ensure it can never happen again. The first government-funded compensation payment was paid out via the Horizon Shortfall Scheme in March 2021 and – since then – it has paid out around 60% of all claims. This amounts to around £179 million to over 2,800 claimants – but this legislation will speed up justice and get the rightful redress for victims much more rapidly. 

The Bill will extend and apply to England and Wales. The Government will continue to work closely with their counterparts in Scotland and Northern Ireland as they develop their own plans. Regardless of where or how convictions are quashed, redress will be paid to victims across the whole of the UK on the same basis. 

The Horizon Compensation Advisory Board’s Chair, Professor Christopher Hodges, said:  

The Government has taken rapid and decisive action to address the widespread injustice to which we drew attention in December.  
We also welcome the Government’s decision to take direct responsibility for delivering fair compensation to those whose convictions are overturned.”  

Kevan Jones, Labour MP for North Durham and member of the Horizon Compensation Advisory Board, said: 

It’s great news that the Government has taken the advice of the independent Advisory Board, on which I sit, and introduced the Post Office Offences Bill. 
This will exonerate hundreds of victims who were convicted as a result of the Post Office Horizon IT system. 
It is essential that we get this Bill passed as soon as possible before Summer recess so that those affected can get the justice and compensation they have fought so long for.” 

The Government acknowledges the risk that this legislation could quash convictions of people who were genuinely guilty of a crime. In line with the wishes of campaigners the Government will make all efforts to ensure this is targeted on those wrongly convicted and make sure nobody who defrauded the system is able to access taxpayer-funded compensation.   

Before receiving financial redress, sub-postmasters will be required to sign a legal statement vowing that they did not commit the crime for which they were originally convicted. Any person found to have signed a statement falsely in order to gain financial redress may be guilty of fraud. 

The Government will continue to push this legislation through Parliament with the aim of achieving Royal Assent as soon as possible ahead of summer recess. Redress will be delivered as swiftly as possible after the quashing of convictions are processed. 

The Horizon Compensation Advisory Board, which includes long time parliamentary campaigners on this issue such as Lord Arbuthnot, Professor Christopher Hodges and Kevan Jones MP, has warmly welcomed the proposed legislation.
