BA has indeed addessed this issue and our flight crews have been told that of as Feb 06 they will be able to remain until 60. The present 55 is contractual to their Pensions, therefore they may still retire at 55. This age change also applies to CC.
Of other concern is the present method of using 'seniority' to appoint / bid for flights / bid lines etc. Under the EU rules that system will be illegal as it is discriminatery.
