On flights out of LHR, I think Bmi should go back to the same as BA and offer refreshments. No need for meal, maybe except in business class, but at least free tea/coffee/soft drinks free in economy, with just a snack like pretzels or shortbread. Alcohol charge for, or possibly free.
Bring back the bmi we know, a quality airline, that offers good schedules and good service, and a good alternate to BA.
