I've said it many times and I will say it again. The 757's are to be avoided at all cost when traveling in F! These seat are the worst possible on a plane. The 757 F seats give me family the impression of the old CI F class in the late 70's to 80's that I used to commute on every week HKG-TPE as a kid.
It's embarrassing that AA, as the largest international airline, still has these things in its fleet.
Yes, they are wide, but who in this world need such a wide seat? I need to put a pillow on each side of me to fill the void in order to be comfortable....
