July 31 LHR-EWR 21K and L. These seats are more comfortable to me than E+ by a fair bit. Slightly wider at 19", slightly better recline at 6" and greater pitch at 38" versus 18.5", 4" and 34" in E+ respectively. The modest leg lift was tough getting to edge out, the button needed a very forceful pushing to work the first time (bad angle, perhaps?) but seemed easier after. The foot pedals seemed jammed in a high position, but I was OK with that. No middle seats is definitely a feature in the 767 P+ section. Food offerings were pleasing to me and my wife but not particularly memorable. The number of choices available to pre-order was quite good. My status and lounge memberships make some of the P+ perks irrelevant, but it's good to know them for our friends.
We were quite happy with these seats for an 8-hour daytime flight, a longer red-eye might be a different thing. Indeed, we flew in Polaris EWR-LHR, but that was because the price for the flight we chose appeared to be only modestly more at reservation.
