To re-hash what has been said before.....
It never was a sponsorship scheme, no matter what was said, you always have paid for it all, you don't get repaid from the airline your pay is just the same as any other pilot, just delivered in a more tax efficient way. And even that has stopped with the introduction of flexi crew.
Go into this scheme with your eyes open, it's a very different market now to a few years ago.
