I'm 6'6" and have pretty broad shoulders. I dont know who in their right mind would prefer 27C over 14B. You dont have to play "take a chance" with having a POS (person of size) end up in the 27A or 27B which would make things sort of uncomfortable for all three of you across. 14A and 14B are both like asile seats, theyre both pretty amazing. you dont stick all the way over in the asile, so you won't get bumped by the cart as much, either.

They arent as amazing as 1A&B, which is where I usually end up and you know why. ;-)
