X3k5 does seem like a Oxford employee, interesting that you say you are 17 and still at school, but know what BA want.
I don't I am 36 have a job on the 737 and did almost all my training at Cranebank (BA's in house training centre)a few months ago. I had the chance to talk to a BA training Captain, he had just had a couple of students doing their LST's (on the 737 as well) and they were ex Oxford intergrated. They had also had to PAY BA for their type rating, so intergrated gets you a job, but you still have to pay another 20K or so........
