US Airways Group chief executive Doug Parker and Delta Air Lines chief executive officer Richard Anderson have urged Transportation Security Administration (TSA) chief John Pistole to reconsider allowing small knives in the cabins of commercial aircraft.
The TSA announced the change last week, raising the ire of pilot and flight-attendant groups that called it an unsafe plan.
In a letter to the TSA, Anderson said the move "will add little value" to passenger security screening efficiency "in relation to the additional risk for our cabin staff and customers."
"We have consulted with our flight attendant group and we share their legitimate concerns," Anderson wrote. "If the purpose is to increase security checkpoint flow, there are much more effective steps we can take together to streamline the security checkpoints."
