TSA PreCheck®

TSA PreCheck Travel With Ease

What is TSA PreCheck?

TSA PreCheck® is an expedited screening program operated by the U.S. Transportation Security Administration (TSA). When boarding domestic and international flights departing from more than 200 U.S. airports, you can pass through security screening faster and more conveniently.

TSA PreCheck Benefits

Reduced Wait Times

With a dedicated lane, the average wait time is under 10 minutes, so you can get through faster. (Based on official TSA statistics)

Simplified Screening Process

You don't need to remove your shoes, belt, or light jacket, and you can leave laptops and liquids (in compliance with the 3-1-1 rule) in your bag.

Benefits for Accompanying Children

If the guardian is enrolled in TSA, children 17 and under can use it together for free.

How to Apply and Use

TSA PreCheck is available only to U.S. citizens and permanent residents. Korean and other nationals can enjoy TSA PreCheck benefits through the Trusted Traveler Program.
