I have to say that a 4th rotation is brave given that they are still sharing the Govt contract with airlines that have been doing it for years. I also notice that in September you can still book an BFS-LHR return with EI for £50 (even cheaper than last year). You can't get near that with BMI and yet they still fill their aircraft. Looks a lot like seat dumping to me (again). Market share is irrelevant if the yield is rubbish.
