Overview
- The agency says Advanced Imaging Technology screens passengers without physical contact using millimeter-wave sensors and a generic outline, reducing full pat-downs.
- Computed tomography scanners generate 3D views of carry-ons so laptops and travel-size liquids can remain inside, though agents may still open bags and the CT tunnel opening is slightly smaller than traditional units.
- Some travelers are assigned enhanced screening based on boarding pass selection and cannot use AIT in those limited circumstances.
- TSA maintains the No Fly List with the Terrorist Screening Center and FBI participation to bar certain individuals from boarding nationwide.
- Cordless hair tools with butane or lithium batteries and butane refills are prohibited in checked baggage, with violations subject to fines of up to $17,062; TSA advises organized packing, valid ID, and considering PreCheck to reduce delays.
