Have just done LHR-BDA return on a 772 in 38A both ways and have to say it was a very comfortable experience. Leg room was excellent ( I’m 5”11). I had two windows as opposed to one in row 39 behind and the IFE box was on the far right hand side next to the isle so nothing much impeding where your feet went. Seat next to me was blocked both ways which probably helped the experience and Y was about 2/3s full both ways so very minimal queues for the toilets with most passengers using the facilities between WT+ and WT likely not realising there were two right at the back.
