I wouldnt worry too much about getting work experience, i mean its real easy to get and most places will let you if you beg enough. Getting a real job is sooo much harder LOL.
If its usefull, i did Aero related work experience with the following:
Agusta Westland
Finnair
British Airways
Air Botnia (now Fin 1)
none of them were crappy 'make the coffee' or customer service crap. All nitty gritty directly related to aircraft - even getting to touch them and play with them
So if u are unsure of who to go for, the above definately take students!!
Keeley, you are a girl, its easy for you to get anything!! bae systems and Quinetiq also do summer placements i think!! Are you on MEng or BEng cos it might be worth getting some ideas for placements for next year.
BTW, i know u
u used to be in my class till last year :P As for me, i got a crazy plan of getting an internship after i graduate! (good luck to me :S) and applying to CTC. I hard quite a few lboro students get into it, so im banking on that :P
