At least three Ryanair flights were cancelled on Tuesday after Italian air traffic control and ground handling staff went on strike.
Passengers who were scheduled to leave Malta at 6.40am to go to Turin said the flight was initially marked as delayed to noon, only for it to be subsequently cancelled.
Passengers intending to catch the plane's return leg from Turin to Malta were checked in normally at 7am, but were left waiting till noon at the boarding gate.
