Hello,
Are you sure that Onur Air have Airbus 320, I think they have A300 and Boeing 737. I'm sorry to tell you that but Turkey is most a 737 country Inter, Pegase, Kthy, Turkish Airlines,Sky....But it's true there are all looking for Captain's and FO's for the summer season, because Turkey is the DESTINATION for this summer.
Sorry Panzer,
I just check the site and you are true

My advice is just to go there, and give your cv by your self. They certainly need you
