When flying, every passenger dreams of skipping long security lines, keeping their shoes on at TSA checkpoints, and avoiding the hassle of removing electronics and liquids from bags. This is where the Known Traveler Number (KTN) comes in. If you're flying JetBlue and have TSA PreCheck or other government-issued trusted traveler status, you can use your Known Traveler Number to enjoy expedited security screening. But what exactly is a Known Traveler Number, and how does it work with JetBlue?

This article covers everything you need to know about the Known Traveler Number on JetBlue—from what it is and how to get it, to how to add it to your JetBlue account and ensure it applies to your flights.

**What Is a Known Traveler Number (KTN)?**
A Known Traveler Number (KTN) is a unique identification number issued by the U.S. Department of Homeland Security (DHS) to individuals who have been approved for one of several Trusted Traveler Programs (TTP). These programs include:

TSA PreCheck

Global Entry

NEXUS

SENTRI

The KTN allows passengers to receive TSA PreCheck benefits on participating airlines, including JetBlue. When you enter your KTN in your reservation, the system identifies you as a low-risk traveler, which qualifies you for expedited airport security screening at most U.S. airports.

### **TSA PreCheck Benefits on JetBlue**
JetBlue participates in the TSA PreCheck program. If you have a Known Traveler Number and it's properly entered into your JetBlue booking, you can enjoy the following TSA PreCheck benefits:

Shorter security lines

No need to remove shoes, belts, or light jackets

Laptops and liquids stay in your bag

Available at over 200 U.S. airports

These benefits apply to both domestic and certain international JetBlue flights departing from U.S. airports.

**How Do You Get a Known Traveler Number?**
To obtain a Known Traveler Number, you need to enroll in one of the approved Trusted Traveler Programs. The most common option for JetBlue travelers is TSA PreCheck. Here's how to apply:

**1. TSA PreCheck**
Eligibility: U.S. citizens and lawful permanent residents

Cost: $78 for 5 years (renewal is $70 online)

Once approved, your KTN is assigned and can be used immediately for JetBlue flights and other participating airlines.

#### How to Add Your Known Traveler Number to JetBlue
You can add your Known Traveler Number to your JetBlue profile or individual bookings to ensure TSA PreCheck benefits apply at security. Here's how:

**1. Add KTN to Your JetBlue TrueBlue Profile (Recommended)**
To ensure your KTN is applied automatically to all your future flights:

Log in to your JetBlue TrueBlue account

Go to “Profile & Settings”

Scroll to “Travel Info” or “Traveler Details”

Enter your Known Traveler Number in the appropriate field

Save changes

This way, every time you book a flight while logged into your TrueBlue account, your KTN will be applied automatically.

**2. Add KTN to a Specific Booking**
If you already booked a flight and forgot to add your KTN:

Go to “Manage Trips” on the JetBlue website or app

Enter your confirmation number and last name

Select your flight

Click on “Edit Passenger Information”

Add or update the KTN field

Alternatively, you can call JetBlue customer service at 1-800-JETBLUE (1-800-473-6632) and request they add your KTN to your reservation.

**Where Is My Known Traveler Number Located?**
Once you are approved for TSA PreCheck or another Trusted Traveler Program, your KTN will be available via:

Your TSA PreCheck or Global Entry approval letter

Your Trusted Traveler Programs (TTP) online account

Your Global Entry/NEXUS card, where it is listed as a PASSID

Make sure the number is entered correctly when booking or updating your reservation—mistakes may prevent your TSA PreCheck benefits from appearing on your boarding pass.

##### **What If My TSA PreCheck Does Not Appear on My JetBlue Boarding Pass?**
If you’re approved for TSA PreCheck but it’s not showing up on your boarding pass:

Check your KTN: Make sure the number is correct in your JetBlue profile or booking.

**Verify your name:** Your JetBlue ticket must exactly match the full name you used when applying for TSA PreCheck.

**Call JetBlue:** Contact JetBlue support at 1-800-JETBLUE and ask an agent to manually add your KTN.

**Airport solution:** Visit a JetBlue check-in counter or speak to a TSA agent before going through security.

**Can I Use My Known Traveler Number for International JetBlue Flights?**
You can use your Known Traveler Number for the departure leg of international JetBlue flights, as long as you’re departing from a U.S. airport with TSA PreCheck. However, TSA PreCheck does not apply at foreign airports for your return flight to the U.S.

For global expedited entry, consider Global Entry, which includes TSA PreCheck and offers faster re-entry to the U.S. via automated kiosks.

Known Traveler Number vs. Redress Number
While both numbers are used in travel screening, they serve different purposes:

Known Traveler Number (KTN): Used for TSA PreCheck and Trusted Traveler Programs

Redress Number: Issued by DHS for passengers who were wrongly identified for additional screening; part of the DHS TRIP program

JetBlue allows you to enter both numbers when managing your booking or updating your profile.

**Who Can Use Your Known Traveler Number?**
Only you can use your KTN. It is non-transferable. Family members, including children, must have their own KTN to receive TSA PreCheck benefits—unless they are under 12 and traveling with a parent or guardian who has TSA PreCheck.

**Conclusion**
Your JetBlue Known Traveler Number is the key to a smoother, faster airport experience through TSA PreCheck. Whether you travel occasionally or frequently, enrolling in a Trusted Traveler Program and adding your KTN to your JetBlue account ensures that you’ll spend less time in security lines and more time enjoying your journey.

If you haven’t yet enrolled in TSA PreCheck or Global Entry, consider starting the process at tsa.gov/precheck or ttp.dhs.gov. Once you receive your KTN, simply update your JetBlue TrueBlue profile or reservation. For assistance, call JetBlue at 1-800-JETBLUE (1-800-473-6632).
