How do I get TSA PreCheck on American Airlines?

Why is my TSA PreCheck number not showing on my boarding pass?
- If your boarding pass does not show your PreCheck status, you cannot use the TSA PreCheck security lanes. For future reservations, log in to your airline account before booking your flight. Booking flights while logged in allows your PreCheck number to be added to reservations automatically.
How do I get a new boarding pass with TSA Pre?
- Again, the easiest solution is to log into your airline’s website and just add your TSA Pre number and then get a new boarding pass. That said, I’ve definitely tried that a few times and gotten shot down because I was too close to boarding time and/or my pass had already been issued.
What is the difference between TSA PreCheck and Global Entry?
- While Global Entry provides members with an ID card, TSA PreCheck does not. Instead, you’ll receive written notice of approval that includes your Known Traveler Number (KTN), which is what determines whether you’ll be able to use the PreCheck lane on any given flight. If your KTN shows up on your reservation, then you’re all set.
