From what I can gather you could probably afford to go integrated. At Cranfield, Cabair run a very well known integrated course and they are closely linked with several airlines, such as Flybe, who are doing a form of sponsorship with them and BA who are considering their graduates for their SSP scheme. In my eyes if you have the determination, the class 1 medical and the cash, go for it! The requirement to start the course is a pass in their assessment. Hope this helps and best of luck
