If even Major Airlines like Alitalia is going to do that, then I don't know how it would ever get better.
And then after the program of 500 hours. Then you are basically still worth nothing. Because airlines want to suck out pilots, so they will not hire you because you have done already TR. But airlines where you should have 1000+ hours TT will not take you either, because you lack experience.
I even cannot get any loan for such programs anyway, but I would NEVER pay for my Line training. That ain't a job. Just an expensive hobby.
You should get PAID to work. NOT PAY to work.
