Authorities inspected a plane at Boston's Logan Airport on Wednesday after a threatening note was discovered on board. No bomb was found and the plane was given the all-clear.
The American Airlines plane and luggage were searched Wednesday by police and a bomb-sniffing dog after an employee found a note reading "Bomb on board, Boston-Miami" on a bathroom wall.
No passengers were on board at the time.
Airport spokesman Phil Orlandella said the search turned up nothing suspicious.
He said passengers on Flight 1318 were transferred to another plane heading for Miami. The threatened flight had come from Dallas, and the note was found during the preboarding process in Boston.
