first of all the political and economical situation in Turkey is getting worse day by day , the local guy's post is totally correct about the salaries. Aviation syndicate(union) of Turkey is totally controlled by THY so improvement for salaries is delayed every month. Even promised rise of 2017. Euro and USD are being expected to be 5 and 4.5 in 2018 by the economists. Also in 777 fleet they stopped giving 8 blockdays to everyone including expats. In narrow body you can begin two different duties on the same day after the new rules published and it is happening now! If you fail every assesment of any airlines around the World then you can consider to come THY but I would never recommend. Stay away as much as you can!
