Just Completed a Round trip with Etihad/VA CDG-AUH-SYD and SYD-MEL-AUH-CDG
Outbound leg, moved to exit seat on flight to AUH the upgraded to PE AUH-SYD (VA metal) asked for a legroom seat at the gate and they upgraded me.
Inbound leg moved to exit seat MEL-AUH and then AUH-CDG they blocked a row of four off for me . If you havent got a good seat already allocated speak to them at the transfer desk in AUH and then again at the gate.
Al Reem lounge easy to get to and comfortable
I know a lot of people complain about EY. But I thought they were quite good - we did the whole way from LHR-MEL, and although I'm not terribly tall, I thought the room was enough, and the seats were like a well worn couch! Service was REALLY good, especially since we went to LHR via QF, so we could compare directly. I'm not sure of the premium cabins, but I imagine that they would be the same. YMMV.
