Does Cabair offer any sort of airline partnership scheme? I haven't looked at Cabair in much detail, but between OAA and CTC, I feel that CTC offer the most promising job finding solution (note: I didn't use the words 'ideal' or 'perfect'). Aside from perhaps a direct sponsorship by an airline, it is arguably your best chance at gaining a job at the end of the various intergrated training programs.
It's maybe worthwhile looking at the FlyBe scheme running at the moment, they invited me along to an assessment day/weekend but I declined as I felt training for an ATPL would be more valuable in the job market than an airline specific MPL if anything were to happen to the sponsor airline.
Oxford still has a very good reputation, when I told my flying school that I was going to do an intergrated course, the first thing they said was "Oh, is that at Oxford?". I feel that CTC is the correct choice for me there is at least a slim possibility I may get a job at the end of it. Something no other training providers can specifically offer.
