A Germanwings plane flying from Hanover to Rome made an unscheduled landing in Venice on Friday.
Airport sources quoted by ANSA news agency said it was not an emergency landing after two people on board were suddenly taken ill.
However, all passengers were made to get off the plane and wait for a rescheduled flight later in the day, Xinhua reported.
Germanwings is Lufthansa's budget airline whose Airbus A320 en route from Spain's Barcelona to Germany's Duesseldorf crashed in southern France on March 24, killing 150 people on board.
