United Airlines is paying to remove a gate from some of its newest planes that’s meant to protect the cockpit from intruders, according to the union for its pilots.

United is getting Boeing Co.’s newest plane, the 787, later this year. Those planes were to come with a folding metal gate that blocks the cockpit when the door is open, according to the Air Line Pilots Association. But United is paying extra to have those gates removed, according to a letter from the union to the airline obtained by The Associated Press on Tuesday.
