I have a quick follow up question: I am on the 40J LGW 772 and currently sat in 2J/K - this is the outbound daytime flight - would you recommend 4AB both in terms of seating and exiting the aircraft? I am aware of the noise coming from the engines on the 777 so return would guess 2AB is better? The seat is a little short for me (but doable) but guess this beats noise from gallery (from BA seatmap the seats seem very close to the galley).
