In 2026, the TSA uses a multi-layered screening process for checked luggage. Once your bag disappears behind the check-in counter, it travels through an automated Explosive Detection System (EDS), which uses CT-scan technology to create 3D images of the bag's contents. If the computer flags a "suspicious" item that it cannot identify, the bag is sent to a secondary area for a physical inspection by a TSA officer. If your bag is opened, the officer will place a "Notice of Baggage Inspection" inside. To avoid delays, it is recommended to use TSA-approved locks, which allow officers to open the bag with a master key rather than cutting the lock. Many 2026 airports also utilize "Facial Recognition" and "Touchless ID" at the bag drop shortcut to speed up the initial processing of your luggage before it hits the scanners.
