Hello Flyguy, thanks for your answer ! Sorry for the late reply, I did have very important exams these last days...

Yes, I know that some European companies are offering an ab-initio program but the problem is that I'm French, so even if, thanks to EU, I'm able to consider this programs, I have to be fluent (or almost) in German.

I'm ready to learn german but it will take something like 3 yrs I think, then there's psychotest and all of that, so it's a lot of investment for something that could never happen but I agree that in theory this the best deal : right seat in a legacy, cost close to 0€... But it's very long (I can't learn german full time with my studies) and very uncertain due to psychometrics...

The last two options I see in Europe are Air France ab initio program (will be able to pass it in 2 years if it's still open) or Wizz Air Cadet program (62k€ and then you have the job).

But I see what you mean when you are talking about those programs and it makes me think once again so thanks !
