Overview
- Reporting on Wednesday noted that TSA has installed some version of CT scanners at nearly 300 U.S. airports, though not every checkpoint lane at those airports is converted.
- The CT scanners produce rotatable three‑dimensional images so officers can inspect bags without opening them, which often lets passengers keep laptops and travel‑size liquids inside their carry‑ons.
- The scanner housings have smaller entry tunnels than some older X‑ray machines, so a bag that meets an airline’s published carry‑on size can still be rejected at the security belt.
- TSA says officers are available to assist and is recommending that travelers check bags that will not fit the machines, but the agency has not set a new national carry‑on size limit.
- Reporters advise Disney World families to measure fully packed luggage including wheels and pockets, avoid overfilling expandable cases, leave essentials in a smaller personal item, and allow extra time to avoid fees or delays.
