Well that is a totally personal opinion based on personal wishes.
Flag carriers are and will be there. Some doing fine, some doing not that fine.
And yes, they do have enough locals. Plenty of british, french, german guys out there with experience. And plenty of them coming out from private schools all over the globe.
The only reason for needing pilots in THY is the "non normal" growth which is leading in a desperate need of pilots. But that will be corrected soon or late.
I hope for our own interest (mine at least) that they'll keep this needs for the next 5-10 years which maybe leads in a career progression for Yabanci FOs like me. If I can leave here after some years with few more hours and € in my pocket that will be ok. If I can do it having some hours on the left hand seat this will be more than welcomed!
