I used Etihad twice and i have/had no complains at all. The vegetarian food they serve was as spicy as I eat at home so loved it. The service overall is pretty good too. The airport as "Ketama" ji already told has wifi(free) and lot of people roaming around(a whole lot of nepali work in that airport too). The airport was dead between 2am to 4 am local time though...

To sum it up all, I had pretty great experience with Etihad as well.
