It was such a shame when Jetmagic and Duo went from the UK scene. They were two good carriers but set up at the wrong time. It is also a shame that Loganair, manx and brymon have lost their identity to BA. Although loganair is bringing back it's true colours on it's Islanders.
BMI regional would be a good airline if it was run slightly away from BMI. Although do they don't fly all domestic they have a brilliant route structure.
