IF you are hired by Germanwings, can you move to regular Lufthansa or not?
Yes. You can move to lufthansa mainline or lufthansa cargo if there are openings and the initial fleet freeze is over.
IF you just quit, is there still a requirement to repay the mortgage on the flight training?
Probably, but i have to say i don't know really, it is not a case that is usually considered.
There is something about that statistic I really do not like. It might tell us how good the selection filter is, but it might also be telling us how doggedly they hold to their initial, possibly incorrect, assessments
During my time there they had a formalized procedure how to deal with cadets that didn't show the required performance. Pretty similar to what most airlines do with normal pilots that flunk their simulator or line checks. Even for us non-Lufthansa cadets that paid for their own training it wasn't different and they had no problems at all to to let anyone go if his performance wasn't good enough, even if it meant a loss of revenue for them.
