The flight departure was delayed because a PJIA worker with one of those florescent vest on came off the plane with a "fanny pack" from the incoming flight. He gave it to the staff that check your boarding pass before you board and then the police showed shortly thereafter. They took the fanny pack back onto the plane while we waited at the top of the jetway for maybe 5 minutes, then we got the go ahead to proceed down the jetway. Funny thing is we never saw the police return up the jetway?
