American Airlines on Thursday began the first U.S. test of new airport-security scanners that provide a more detailed view inside carry-on luggage and may allow travelers to keep laptops in their bags.
The CT scanner, using technology borrowed from the medical world, is being used in a security checkpoint lane at Phoenix Sky Harbor International Airport, the airline said in a statement. The testing, at Terminal Four, is being conducted with the Transportation Security Administration.
The experiment comes as the U.S. Department of Homeland Security considers whether to expand a ban on electronic devices in airliner cabins that began on some international routes in March. CT scanners are better than existing X-ray devices at detecting explosives, meaning that at some point they could enable passengers to leave laptops, other electronics and possibly even liquids in their bags, vastly simplifying airport security.
