I missed 4 segments in the forward cabin on what was supposed to be day one of ops on several domestic routes in November 2012. I finally got the chance on 5/24 but in E+. The thrill wore off pretty quick into the flight. Other than the cool windows, there wasn't much exciting. humidity did seem to be a little higher but the the engines weren't very quiet except for a few minutes in the flight from ORD-IAH.
Y+ seat was good. Seemed like more recline without sacrificing legroom due to the bottom cushion sliding forwards. Although the AVOD screen seems too close. I wouldn't go out of my way to fly on it again
