Flew JFK to Abu Dhabi on a A380 800. Plenty of spare seats and room to stretch out.
Flew Abu Dhabi to Perth on a A330 200. Same situation so got plenty of sleep.
Food is good, but potato was a big contributor to the meals, often getting potato salad, and hot or warm potato in some form in the main meal. The E-box entertainment has wide range of programs and a few games. Didn't really use it, when I had opportunity to sleep. Announcements made in both English and Arabic. Sometimes Arabic is first and then English, sometimes vice versa. WOULD use Etihad again as a carrier.
