A very spacious lav.^

Seriously I think the lav in the back is much better than the front one, especially if you're trying to stand while using it. I find I have to duck my head or lean backwards because of the curvature.
Haven't sat up front on an AS E175 but have on AA and UA. 2A is definitely my favorite.
