I was on the 6:30pm JFK-LHR on a refurbished B777 on Sat 23 Oct. It seemed very similar to the AA seats, but the BA version has a door. Not quite as posh as a Q-suite, but decent.
The food left a bit to be desired though.
I was in the 2nd cabin, second row, right window. In the lounge they asked if I wanted the bulkhead, but there was someone across the aisle so I declined. I was happy that I had, since the bulkhead didn't seem to have any extra room, and it got some light/noise from the toilets and galley ahead. As it worked out, someone else was in that bulkhead seat, and I don't think he was happy with his choice. I had an empty seat across the aisle from me (I'd guess the Club seats were 70% on that flight, if that).
