Another airline executive is speaking out on a plan by federal regulators to allow passengers to bring small knives into the cabin of commercial planes.
Doug Parker, chief executive at US Airways, wrote to the head of the Transportation Security Administration on Monday, asking that the agency reconsider the proposed policy change.
The TSA announced last week plans to let passengers carry small folding knives -- with blades no more than 2.36 inches long and 1/2 inch wide -- into the cabin of a commercial plane, starting April 25. It is the biggest relaxation of the list of prohibited items since the 9/11 terrorist attacks.
The TSA has defended the policy change, saying it brings U.S. airlines in alignment with international security standards and frees airport screeners to spend more time searching for serious threats, such as explosives.
