Southwest TSA PreCheck

Southwest Airlines offers a program called TSA PreCheck that speeds up security screenings at select airports. Southwest TSA  PreCheck only computers and compliant liquids may be brought on board as carry-on items, and holders are allowed to take off their light coats, belts, and shoes. To use this service, you must apply for TSA PreCheck, have your background verified, and have a Known Traveler Number (KTN). Your TSA PreCheck status will be displayed on your boarding pass when you book a ticket with Southwest and enter your KTN. This facilitates the use of dedicated security lanes, which speeds up and enhances your travel experience at airports.
