I don't know what's up with the Flight Crew in BA all the time they seem to give stuff away, £10m this occasion to preserve the precious Bidline and status quo..
As one Captain said to me the other day "If only BALPA were a bit more like BASSA..."
No doubt BALPA were shown the "books" at BMI to see if the airline is really in the pomme frite, before recommending capitulation. Appeasing Willie is playing straight into his arms. Look at the IBERIA pilots; they are not going to give in without a fight. No doubt they are supporting their cabin crew colleagues, unlike the strike breaking mob of pilots who went into work serving drinks in the cabins.
So here is your reward for helping BA in its "fight for survival". You have been screwed. Enjoy!!
