“The aircraft returned to the gate where it was met by law enforcement and the passengers were removed and temporarily banned from flying with us,” the airline added. However, all of the passengers were forced to deplane out of an abundance of caution and the flight was delayed. “The flight attendants have received threats from customers on board the aircraft,” the pilot responds. “Do you need us to contact law enforcement?” The controller then tells pilots to return to the gate, and “we’re going to have law enforcement standing by.”
