People will go to BA because it's BA, irrespective of conditions at bmi. The Roster disruption is nowhere near as bad as you make out, and the lifestyle can be stabilised by judicious use of Block Windows.
Apart from the perennial whingers (not pointing a finger anywhere, of course) there's a pretty good bunch of people to work with, reasonable money and good route variety if you're on the right fleet (the one from Seattle, that is!).
