Worked Flt 179 JFK-SFO tail #398 today, and I must say, despite a very hot cabin during boarding, everyone seemed to enjoy the new seats. I was pleasantly surprised to see that they all actually worked, and at least 4 people went to the zzz position and stayed there after breakfast.
This is the 2nd plane that received the new seats, and it seems like things are looking a little brighter. I do like the new interior, although I wish that they extended the new bins back into Y.
I know that it gets very cramped for people in the window especially, and it's a real pain in the rear to exit the seat when the aisle pax is sleeping. I don't see any change to that, but over-all I think everyone enjoys the seat.
