We can talk ad infinitum about the ethical case for changing retirement age. The reality is that happens will be a result of the interaction of government legislation with what is economically convenient for the airlines. In the case of BA, I have had it from the horse's (kangaroo's?) mouth that, although the status quo will not change until the law does (to avoid employees suing the airline), they will not put up a fight when told to change the 55 limit. What this will then move to is another matter, but my guess is that whatever the answer is, it is likely to be the same for all UK airlines. BA have a huge pension problem and anything which defers liability is bound to be welcomed.
