As you can see, the ones actually working for QR nowadays don't have much to complain about, probably on the past things were really unbareble. I'm on 320 and the only bad thing I've got to say is that the destinations served by this fleet are getting worst every month, not many options when it comes to layovers and too many Pakistan/India night flights. Some times it feels like I work for PIA or Air India, other than that I'm 101% satisfied with my decision to come, actually regret not to come earlier.
