I'd suggest going down to your local light aviation airfield(s) and seeing what jobs are going over the summer. It may be fairly menial, washing aeroplanes, answering the phone, refuelling - but it's around aeroplanes, will give you loads of chances to chat to (and more important listen to) people who spend their lives around aeroplanes - including most likely aviation professionals from all arenas, and the odds are you'll have good fun as well.
If you post on here where you live, I and a few others should be able to make some suggestions about where you could try.
