You don't appear to be a regular flyer and I think you might be letting your preconceptions or prejudices get in the way of rational judgement.
First of all, although I don't like the Dash, mainly because of the noise and vibration, I think you should be aware that you can get a normal IATA sized suitcase in to the overhead bins (sideways but in, nonetheless). More or less the same with the Emb jets. I've done it many times.
Furthermore FlyBe's approach to cabin bag control is more friendly, sensible and practical than the Bag-Snatch Squads employed by EZY, RYR et al.
Secondly EZY now offer allocated seating so you don't have to join the scrum to board.
You have clearly already decided to go with EZY from BRS so why use the forum as an excuse to have an un-necessary go at an airline that is in some trouble? If they ever were to disappear, we would all be worse off.
Try and be a bit more sensitive to those who work there and might be worried about their futures.
