Adding a Known Traveler Number (KTN) to your frequent flyer profiles

Known Traveler Number

What’s a Known Traveler Number?

Once you’ve been approved for one of the Department of Homeland Security Trusted Traveler pre-screening programs (TSA Pre✓, Global Entry, SENTRI or NEXUS), you are allocated a KTN. Your KTN is your membership number, also known as a PASSID, Trusted Traveler or Secure Flight number, and it’s used to further identify yourself and to potentially prevent misidentifications while traveling.

Before flying with a particular airline, you need to add your KTN to your airline profile or you won’t be able to benefit from your chosen program. You can find your KTN here if you are a TSA Pre✓ member or here if you have Global Entry, SENTRI or NEXUS.

Tell me a little more about the various pre-screening programs…

Homeland Security has this nifty comparison chart of the four pre-screening programs online here, showing the current eligibility requirements, application fees and more. You can read our guide to Global Entry, NEXUS and SENTRI here, an introduction to TSA Pre✓ here and a post about which credit cards refund you the Global Entry application fee here.

How do I add my Known Traveler Number to my airline traveler profiles?

These airlines offer TSA Pre✓ and your boarding pass will show that you are a member:

  • Air Canada
  • Alaska Airlines
  • Allegiant Airlines
  • American Airlines
  • Delta Air Lines
  • Hawaiian Airlines
  • JetBlue Airways
  • OneJet
  • Southwest Airlines
  • Sun Country
  • United Airlines
  • Virgin America
  • WestJet

Once you’re in this program, you should add your KTN to your airline traveler profiles – for example, you can log in to your AA account here and scroll down to add the number or log in to your United account here and add the number in to the Known Traveler Number/Pass ID field. Some airlines will let you add the number to reservations; JetBlue lets you add it to a new reservation, an existing reservation or even when checking in online.

Similarly, if you are a Global Entry, NEXUS or SENTRI member, you can enter your membership number into your frequent flyer profile with the airline and/or add it to the relevant field when booking flight reservations.

What else do I need to know about my Known Traveler Number?

If you have an existing reservation, but you are unable to add your KTN to your frequent flyer profile or to a reservation, contact the airline directly so that you don’t miss out on the benefits of your chosen Trusted Traveler program when you fly.
