LGW15,
There is more to consider than you have mentioned for the pass. I'm no official but it may be harder for you to obtain a pass because you have no criminal record. Not having a criminal record is not the same as a clean record. You could have a string of offences against you but have had to been handled and recorded differently. Insurance is another factor. Does BAA have liability for under 16 "staff"? Can't see why they should, not many people airside under 16. I really don't want to put you off, just show you the other side of the fence. Keep on at them though. Maybe letters from headteachers and other reputable sources would help sway them.
Good Luck
The Reverand
