There is far far more to this industry than training courses. It is the insights handed down from generation to generation and the mistakes of those that have gone before that make a true airline employee - not a week in school and here's an aeroplane.
I am sure DJ will find that culture if they want to, but for now it is mostly Dicky fluff.
Recognise that and you are half way there.
