I was grateful, while I was in year 11, that I was given the opportunity to do work experience at Gloucestershire Airport. The title of my role was 'General Airport Administrator' which basically meant that I sampled all aspects of life at the airport, such as Air Traffic Control and the airport fire service.
It could be very worthwhile to enquire at the smaller airports as the chances of gaining a succesful placement are probably higher.
My experience at Gloucestershire Airport has made me commit myself to a career in avation - preferably as a pilot
I will have to wait until I get my degree though and then, hopefully, I can train
