cornishphil, the flights operate direct from Plymouth on some routes but operate a sort of triangular pattern i.e. Plymouth-Newquay-Newcastle-Plymouth-Newquay-Dublin-Plymouth-Newquay-Glasgow.
I don't know what has gone on the past few days. It's unusual for so many cancellations with no replacement aircraft. Can only think they have two unserviceable aircraft or is it something to do with flight routing restrictions or ill crew?? The Gatwick and Manchester/Leeds flights seem okay, it's just the new routes.
