No cadet scheme in Europe is free in the long run, not even the initial costs. As Ginger said, they can be dressed up in different ways, they will all be similar when you know and understand the numbers when you join.
Completely agree, it is easy to look at the BAFPP as free and money for nothing, it isn't. You go through exactly the same channel as you do with easy jet, i.e. a cadet training contract through APL and managed by CTC, regardless of whether you are training at CTC, FTE or OAA.
The main benefit with the BAFPP is that they may ( it very much depends on your financial situation and credit rating ) offer to secure a BBVA loan in order for you to pay for the training with your integrated provider.
The best European scheme out there at the moment is probably the Aer Lingus one.
