Fast Track Security in the USA TSA Precheck is a service that allows some passengers departing from US airports to fast track the security screening process.

While both services aim to expedite the airport security process, they are fundamentally different programs with distinct geographic reaches and eligibility requirements. TSA PreCheck is a specific U.S. government program managed by the Transportation Security Administration; it requires a background check, fingerprinting, and a $78–$85 fee for a five-year membership. It allows travelers at over 200 U.S. airports to use dedicated lanes where they can keep shoes, belts, and light jackets on, and leave laptops and liquids in their bags. In contrast, "Fast Track" is a generic term used globally for priority security lanes often sold as a "pay-per-use" service by individual airports or third-party providers. Fast Track is available in major international hubs like London, Dubai, and Singapore, and usually does not require a long-term membership or background check. Therefore, if you are traveling internationally, TSA PreCheck will not work outside the U.S., making Fast Track the go-to option for skipping lines abroad.
