Can you add TSA PreCheck after booking?
For existing reservations, you can manually edit each flight to add your PreCheck number before check-in or call customer service and ask that they do it for you.
You can update existing United reservations through the "Edit traveler information" option in Manage Reservations, on an airport kiosk or in the United app. If you add your KTN after checking in, you'll want to reprint your boarding pass or pull it up on the United app.
You can pre- enroll and make an appointment online or walk-in at an enrollment center. To apply for TSA PreCheck®, travelers must go in-person to an enrollment center to provide documentation and fingerprints. Applicants pay a non-refundable $85 fee to cover the cost of background checks.
Existing reservations can also have PreCheck numbers added. Then, on Delta's website, find your reservation and update your passenger information. You can add your Delta Known Traveler Number (KTN) to your profile using a computer, tablet, or mobile device. Firstly, go to Delta airlines official website and sign in.
A Known Traveler Number (KTN) is issued to all individuals approved to receive TSA PreCheck® expedited screening. The KTN must be added in the KTN field when booking airline travel reservations to have the TSA PreCheck® indicator appear on your boarding pass.
