why would they choose a foreigner instead of a local chap? It's truly not worth it.
Absolutely correct, but as already said that's how it works with any other national carrier. Priority is always given to the own countryman and there are usually plenty of them.
As I mentioned earlier, the waiting list at LH is long, even peolpe who already passed the LH selection process have been put on hold for several years, they have been told by LH to go to University and study (if they had any plans doing so) or do an apprenticeship meanwhile. So it's simply not worth it, as already mentioned.
In general it can be said, getting on an airlines sponsored training program is usually always difficult because there is a huge number of applicants and competition is high. Anyway good luck!
