I wasn't referring to just IOM. Stobart is now operating on more Flybe routes than advertised. MAN-SEN for one. And you will get the odd lane pop up when FlyBe don't have an aircraft available due to their own aircraft going technical. I know, it's happened to me. (And is particularly annoying when you have reserved a seat at the front based on a Dash only to find that it's an ATR which loads from the back.)
The Loganair franchise is a legacy but costs will still be washing through the system.
Anyway, I'm sure there'll be another excuse for poor performance.
