TSA PreCheck is a service provided by Southwest Airlines to expedite and simplify the passenger security screening process. Southwest TSA PreCheck travelers can obtain a Known Traveler Number (KTN) by participating in TSA PreCheck, which entails a $78 charge and background check. To guarantee that you get TSA PreCheck benefits, this KTN needs to be uploaded to your Southwest booking or Rapid Rewards profile. If your boarding pass has the "TSA Pre" signal on the day of your travel, you can use accelerated security lanes. Wearing shoes, belts, and lightweight coats is permitted with TSA PreCheck. Laptops and liquids should be packed in your carry-on. More than 200 US airports provide this service.
