What Emma Royss said.
Having been in airlines in all three regions including at THY. Comparing the 3 is like comparing 5 star hotels to youth hostels. In Turkey you are a second class citizen, second class pilot and you live in Turkey! In Dubai they may treat you harshly at times but they treat everyone equally harshly (wrt to pilots not) but at least you ahve a great quality of life better than Europe and bucket loads of cash to go with it.
But Emma's message is soooo true if you are an FO in any of these places except Dubai expect life to be a series of scares and eGPWS warnings.
I may have left Dubai feeling like my bucket was full but Turkish was about leaving to save my life!
