How much is Delta TSA PreCheck? TSA PreCheck itself is not directly associated with any specific airline, including Delta Air Lines. Instead, TSA PreCheck is a program managed by the Transportation Security Administration (TSA) in the United States. The cost to apply for TSA PreCheck is $85 for a five-year membership. When you apply for TSA PreCheck, you'll undergo a background check and interview process to determine your eligibility. Once approved, you'll receive a Known Traveler Number (KTN) which can be added to your airline reservations. This allows you to enjoy expedited security screening at participating airports, including those served by Delta Air Lines. Click here for more......See More
