Surely it's obvious!
No it's not. I wouldn't expect anybody who has not been privvy to the information given in the documents/meetings and is not currently in BA to understand all the issues at stake.
Also you seem to be under the impression that this is some form of negotiation. It's not. The decisions have been made the trains about to leave. We are being asked (thanks to BALPA, because there were many on the borad who didn't want to ask) if we would like to get on board YES or NO.
IAG have made it clear they will not run shorthaul at a loss. Stretching all pay points for all pilots does not solve their problem.
Whether we like it or not the airline industry is evolving thanks to lo-cost. Those who refuse to accept the new order are dying (Qantas/Iberia and others). I don't have an APS pension, Barp guys don't have a NAPS pension, new joiners will not have 24 pay points. but it is for these reasons the company is still here and has not gone the way of others.
Do those who criticise BA pilots for not defending APS seriously think BA would still exist today if changes hadn't been made?
