If you don’t already have TSA PreCheck, you’re missing out. By streamlining security and cutting down on wait times, the program helps make travel a less stressful experience. However, it only does so when you actually use it, so we strongly encourage you to double-check your frequent flyer accounts and make sure your Known Traveler Number (KTN) is saved on your profile.

This nearly cost me dearly last September, when my wife and I were traveling to New York City on JetBlue. We were booked on separate itineraries, and when I completed her online check-in, the TSA PreCheck indicator was conspicuously absent from her boarding pass.

I had no idea what went wrong, but when I went to update her passenger details, I noticed that her KTN was missing:

I added it, undid her check-in (fortunately, JetBlue makes that very easy) and then re-checked her in. Voila! The glorious PreCheck icon appeared on her new boarding pass.

The temporary moment of panic could’ve been avoided had her KTN been saved on her TrueBlue account, which it now is. Here’s how to do that for the major airlines in the US once you’ve logged into your account:


  • Visit Profile and tier status
  • Click on Traveler profiles
  • Click on Edit my information under International Travel Information
  • Enter your KTN, then click Save


  • Click on Your account
  • Click on Information and password
  • Enter your KTN, then click Save


  • Click on Go to My Delta
  • Click on View my profile
  • Find Basic Info, then click Open
  • Click Edit in the Secure Flight section
  • Enter your KTN, then click Save Changes


  • Click on the TrueBlue icon at the top right
  • Click on Profile
  • Click the pencil icon next to TSA PreCheck
  • Enter your KTN, then click Yes, Update


  • Click on My Account
  • Under My Preferences, click Edit
  • Enter your KTN, then click Save


  • Click on View account
  • Under Profile, click on Edit Traveler Information
  • Expand the KTN/Pass ID section, enter your KTN, then click Continue

All it takes is a few seconds to potentially save hours of hassle on your next trip, so be sure your Known Traveler Number is added to all of your frequent flyer accounts! And if you’d like to enjoy expedited screening for free, check out the Top 6 Cards for Global Entry and TSA PreCheck.
