Cheers for the replies chaps, got all the info I needed thanks to the prune!
Indulagence is for a serving members, their spouse and children.
The original question stated 'one of the lads is posted....' does not sound eligible anyway.
The lad who has been posted is in the RAF, I'm in the RAF and the other lad that would be coming out is in the RAF. Sounds like we would all be eligible for an indulgence flight.
Probably right tho, I'd probably be safer with a flight with Virgin or BA in the long run.
Thanks folks
