IMHO a turning point is approaching.
WW will have to leave BA, maybe not immediately but certainly in the not too distant future. He will go with a golden handshake and a chorus of support from 'The Board' who actually will be glad to see him go. But publicly the politics will have to be seen otherwise. The new guy will have a mountain to climb but a few concessions to staff will have him looking good externally. But beware internallly as all thse CEO's are the same in the longer term. (save money, increase profitability, cut staff costs)
BAA is dying on its feet. Only a matter of time before its parts are sold off. But who will be brave enough to take on the monster of LHR?
