TSA PreCheck is a trusted traveler program managed by the Transportation Security Administration (TSA), designed to provide expedited security screening at U.S. airports. Eligible travelers can move through dedicated lanes without removing shoes, belts, laptops, or light jackets. The goal is to reduce wait times and improve passenger convenience while maintaining security standards.
When you fly with Delta Air Lines, your TSA PreCheck eligibility is automatically recognized if your Known Traveler Number (KTN) is correctly linked to your booking profile or reservation. Once validated, the TSA PreCheck indicator appears directly on your boarding pass, whether printed or mobile.
The system cross-checks your passenger data with Transportation Security Administration databases during check-in. If everything matches, your boarding pass is digitally flagged for expedited screening.
