I would advise you to go to one of the RAF flying clubs, the flying will keep you current and there is a very good chance that some of the instructors will be in or only just out of the airline business.
Current advice from inside the airline world can be just as useful as the flying, the RAF can be very insular at times so getting a view from outside can be helpfull especially for those who don't work in the multi-crew environment.
