Flew it for the first time on Qatar Airways DOH-DXB. Was seated right next to the engine. was a fairly smooth and quiet journey. (all 45 minutes)
A couple days later, flew a completely full 787 DOH-LHR. No problems again. The 3-3-3 configuration on Qatar's fleet is annoying though. Fortunately had three in our party.
Would fly again, wont go out of my way though. The wing tips were a little strange to look at.
