Announcement on an FR at GRO: "If there are any passengers on board this aircraft who are travelling to Paris Beauvais, would they please disembark and go to the aircraft parked on the next hardstanding, as we are heading for Rome Ciampino".
Two red-faced people got up, removed their handluggage, and struggled down the aisle, to the accompniament of sarcastic cheers and applause.
