Bof - I seem to remember that one either had to go to an aircraft of 20K or less, as a captain, or one could move to the RHS of any size of aircraft? This meant one could stay employed by the same company at the top of the F/O payscale, etc. it being generally felt even then that raising the unrestricted age to 65 was only just around the corner, so the careers of the younger folk would not be adversely effected. I certainly planned on a retirement age of 65, not 60.
