How to Add TSA Precheck to Turkish Airlines? To add TSA Precheck to Turkish Airlines, passengers must first enrol in the TSA Precheck program through the Transportation Security Administration's website. After completing the application process and passing a background check, passengers will receive a TSA Precheck Known Traveller Number (KTN). To ensure that their KTN is added to their Turkish Airlines reservation, passengers should enter it into their frequent flyer profile or provide it at the time of booking.
