As far as Buzz is concerned, it's business as usual - until 1.4.03 when Ryanair come in and decide what to do. A hunch says that having a cadet sponsorship is unlikely. I imagine that the management at Endeavour house have more important things to worry about than sponsorships.
This leaves the problem that you may well get selected for the cabair part of it, only to have the deal taken away from you in April. By then you have already put down you're £25.000 merely to become a self sponsored, and now short of funds, student at cabair.
Remember, none of these schemes are really sponsorships - they're loans, with the possibilty of a job at the end.
