Well, considering the fact that almost as many airlines have started and stopped longhaul routes from places other than London as are in the Flight Directory, the fact that bmi are still there and investigating new routes suggests to me they are doing better than some. If it was so awful, it would have brought the airline down by now - the revenue associated with longhaul is large!
Let's face it, Antony - you left because you didn't like it. You're hardly likely to start saying now that bmi has any redeeming features. But you're hardly likely to make an objective, balanced judgement on bmi from your situation.
Oh and by the way, your previous post was not as transparent in meaning as you thought it was - I wanted clarification too.
