both hands!!!!What is your drinking hand? If you drink with your right, then you want the aisle on your left hand side. So if you want a window then the K seat is for you. If centre, then D. Substitute A and F if a left drinker.
im right handed, so ive chosen 20K at the moment, apparently 19 and 21 are windowless
just seeing maybe the front 2 rows are better
first world problems
