Regarding Work Experience. I did my Y11 work experience at the airport covering various departments such as Baggage Management, Apron Control and Information Desks and yes i'd recommend it. Your best bet is to contact HR at the airport. I did previously contact Louise Kania although I'm unsure if she still works there. They only take on one work experience student per month (or did in 2005 when I did mine) so it is best to contact them asap. Unfortunately I don't have a number for you but i'm sure browsing the website will produce a result.
All the best
