I'm debating between 26 A/L and 26 C/J on a daytime flight to London. Seems to me like the big question is whether I want the exit door protrusion to be able to put a foot up on it or if I want to avoid it. Will I be able to stretch my legs out straight in front of me, or does the door come into the cabin enough that if I would have to shift them and be in my seat-mate's legspace? Does anyone have any data on just how many inches there are between the seat and that exit door?
