This will primarily be rolled out at larger airports with more than one TSA Pre✓™ lane.

TSA Pre✓™ eligible passengers, who prefer to be screened via an AIT, will now have the opportunity to do so at these select checkpoints. Many passengers with joint replacements, prosthetics or other medical devices that would regularly alarm when passing through a walk-through metal detector often prefer this technology because it is quicker and less invasive than a pat-down. Unlike standard lanes, passengers will not be required to divest their shoes, light outerwear and/or belt in the AIT.

Previously, if a passenger alarmed when passing through the walk-through metal detector after multiple passes, that passenger would be required to receive a pat-down. Passengers at these select TSA Pre✓™ checkpoints, where available, will now have the option of being screened via AIT, possibly precluding the need for a pat-down.
