Really he must be in the minority because the Association of British Airways Pensioners is full of exstaff complaining and contesting it. There are obviously a lot of self righteous people about.!!!!!!
By the way not only were people told when they joined the company that they would get staff travel for life, but when I left I had written and signed documents by the then Personnel Officer to the effect that there would be staff travel for life and my entitlements.
I think that if you were in the same situation - exstaff with entitlements running out you might feel differently - perhaps your father doesnt want to travel any longer but I do.
