TSA Pre✓® is an expedited screening program that enables identified low-risk air travelers to enjoy a smart and efficient screening experience. For TSA Pre✓® travelers, there is no need to remove shoes, 3-1-1 liquids, laptops, light outerwear or belts. Today, TSA Pre✓® has more than 450 lanes at 200+ U.S. airports. The TSA Pre✓® application program allows U.S. citizens and lawful permanent residents to directly apply for TSA Pre✓®. Once approved, travelers will receive a “Known Traveler Number” (which needs to be added to a travelers airline profile and reservations) and will have the opportunity to utilize TSA Pre✓® lanes at select security checkpoints when flying on the 50 carriers that currently participate in TSA Pre✓®.
