Chaps, I'm sorry to tell you that there are currently NO sponsorships, in the sense that someone else pays for your training. There are assisted schemes, where costs are paid by a pre-arranged bank loan in your name (which you have to repay), and there are a few partial sponsorships, where a (small) proportion of the costs are borne by an airline. And then there is the system that most people use: they find the money themselves.
Sponsorships have gone, at least in UK. They are unlikely to return in numbers of any significance.
