The Etihad OMA used to state we could sit in any suitable cabin seat or the crew rest area. Now it says not to sit in any passenger seat....period...only horizontal rest in the rest area. That's real hard to do especially on a morning departure to SYD when you really arent sleepy but would like to rest sitting down, maybe watch a movie or catch up on the computer... Its causing some morale issues down here. The travelling engineer gets a seat, but the captain and first officer dont.
