Don't forget that before the enormous pay packet, you also have to fork out 23000 Euros for the type rating, at your own expense and risk, with no guarantee of employment (though it is fair to say the prospect of employment is high).
At least with some other lo-co operators, basic pay is much higher from the word go, and type rating loans are repaid to you over a (typically) 3 year period, though the initial risk and costs are still your own, also without any guarantee of employment.
