LOS ANGELES, Calif. — Flight attendants for U.S. airlines plan to distribute leaflets at LAX and other airports across the nation today to demand that small knives be kept out of their cabins.

The Association of Flight Attendants members will pass out leaflets at LAX and seven other airports asking passengers to demand that current regulations not be changed, as the Transportation Security Administration plans to do.

The TSA has announced plans to allow small pocket knives to be brought aboard planes, with the goal of increasing enforcement against larger potential weapons by not worrying about smaller implements. But the union decries any move that could make flight attendants and passengers “written off as acceptable casualties.”

“Risk-based security screening makes sense,” the union said in a statement. “Introducing risks into the system does not.”

The leafleting is planned for LAX and airports at Chicago, Denver, Phoenix, Philadelphia, Pittsburg, Seattle, and Washington/Dulles. The local effort will be at the Bradley International Terminal departure level from 12:30 to 2 p.m.
