Go to OATS. I left in July and managed to get a job flying B757/767 within two months. Don't believe what they say about helping you find a job, it is complete horse s**t!! As far as I can tell from my course, the people who were recommended didn't get jobs and the people who weren't, did.Forget Cabair I have heard quite a few things about them. Maybe consider BAe systems, had a couple of friends who went there, one got a job with loganair and the other got a job with the airline I landed a job with.
Accomodation - for the first couple of months use the school's accomodation. Definately do not take an Upper Heyford bungalow - they are revolting and you feel like you're in a prison camp. Stay in Langford and then get some mates and rent a place in Woodstock. I was paying £250 p/m which is about right. Or you can rent a room, look in the window of the newsagents next to the co op. Woodstock is the place to be as kidlington's traffic is awful. The pubs in woodstock are a good laugh and normally there are quite a lot of ladies around.
Enjoy the course and remember how much you are spending and you'll do well.
