There should be no need to leave and join FTRS at 55 from next spring. My deskie told me all PA aircrew will be offered service to 60yo on current terms (ie 75 or 05).
I did some sums on the pension calculator and if I PVR aged 59.5, there's no EDP, only a slightly reduced gratuity & pension.
Perhaps it hasn't caught up with reality yet but it's certainly a question I shall be asking.
