I'm personally impressed with all of the improvements in the last year and especially last six months
Like "Gorter" said, I also came here with my eyes wide open and wasn't really considering it long term.........but it is moving in the right direction and now I have to say if it stays this way I have to rethink my options.
I fly with Europeans, Australians, Asians, Americans , S.Americans etc.....I honestly hear very little bitching and most people are relatively happy ( 777 fleet)
I personally find a huge difference in quality of life depending on where you live in Doha. There are still a lot of cons but the pros are increasing and if you are lucky and don't fall into trouble, it can be a good job.
