Why Can’t I Add My Known Traveler Number To My American Airlines Reservation?

If you can’t add your Known Traveler Number (KTN), call +1-833-770-4333 to get assistance from American Airlines’ TSA PreCheck desk. Many issues arise from mismatched names or expired KTNs, which can be fixed over the phone at +1-833-770-4333. You can also edit your reservation in “Manage Trips,” re-enter the KTN, and save. If errors persist, the representative at +1-833-770-4333 can manually attach your KTN to your booking before check-in.
