Prior rules required only laptops to be removed for separate screening. The new rules significantly expand the number of electronic devices that will need to be removed for screening and help government employees get a clearer view during X-ray screening.
TSA said the new rules have been in place in a pilot project at 10 U.S. airports including Detroit, Los Angeles, Boston and Phoenix, and will expand to all U.S. airports in the months ahead.
The new enhanced security rules at U.S. airports only apply at standard security lanes - not at lanes for travelers who are in "pre-check" programs.
Airlines for America, a trade group representing United Airlines [UALCO.UL], Southwest Airlines Co (LUV.N) and American Airlines (AAL.O), said airlines "remain committed to working collaboratively with DHS officials to strike the appropriate balance of maintaining the efficiency of the system, while ensuring the highest levels of security are in place."
