Once more I´m the one to shed pessimistic (or better ´realistic??´) light on the subject.. Not part of my nature in general..
..Some friends of mine applied recently with 3000 hrs+ on Boeing 737s-- with one of them even living in Trier (close to LUX). And: No, these guys are not flying for LUXAIR (which ocassionally seems to have a negative impact on the outcome of applications sometimes). End of story: They got rejected for reasons the Interpersonal guy couldn´t really explain himself either...
End of story: Sure, keep on applying, 737azf. But be prepared to get some non-commiting and non-personal letters of rejection.
Whether it´s worth the effort... Well: You´re gonna here some VERY interessting but differentiated opinions on that after getting in. But then it´s too late to change your mind!
Cheers,
CTS
