Max,
The only annoyance, to be honest, would be toward the intial BAPLA issuance of 'No BA pilot would be disadvantaged'. Not toward the BMI guys who, like the rest of us, are only pawns in this game and do as they are told, albeit with a modicum of influence through the BMICC.
Once the ripples settle out though the overall situation with increased airframes, new routes etc. will be to all of our advantage, The BMI chaps/chapesses might well find being rostered to 850 hours and the workload a slight increase but the stability is far better.
BMI Baby and regional, whilst very unfortunate and a very good friend of mine works for BMI Baby soon to lose his job, were never a part of the buyout. Just as BMW wanted Rolls Royce and Mini they bought the whole and stripped and sold off what they didn't need. It happens all the time in business. Unfortunate but that is the way the world works.
