Hubby and I are flying to LHR from JFK this coming September. I've flown on this 777 several times and have always gotten 16J, but I do find the tray annoying and the number of people that congregate in the area annoying. I'm only 5'2" and my hubby is 5'11" and about 250. So far we have our pick of MCE on the flight and he flies better when he's next to a window. Should we go for 18K and 18L? Do those seats recline back just as far as the other's? For me it is not an issue, just worried about his comfort. Hoping we get upgraded, but if not, want him to be comfy on his first flight to LHR.

Thanks!
