How do I add my KTN to previous reservations?

Contact your airline by phone or online to add your KTN to any existing reservations or reservations made before you received your KTN. The airline also can confirm that your first/middle/last name are in the correct Secure Flight fields. The KTN will be submitted along with Secure Flight passenger data to TSA. Remember to enter your full name, date of birth and KTN exactly as you provided during enrollment.
