Hi Brenoch!
757 fleet of Air-Astana consist of 3 757-200 (dry lease) and 1 757-200 (wet lease from Atlas Jet Turkey). Air-Astana used foreign pilots for 757(dry) fleet from BA, Thomas Cook and Transavia. There is only one pilot (BA 757/767 Cpt.) in Air- Astana now (757 dry fleet). I am local. Foreign pilots could understand us very well. We got great help from them. They understood us and we understood them.
