Look, I'm a gentleman so I'll pitch in but if you're a woman or elderly person who KNOWS you can manage to lift your bag above your head, shouldn't you just check it? You KNOW going in that you're going to cause boarding congestion and be completely dependent on the kindness of strangers to stow your bag. Should the airlines make you perform a feat of strength when checking in with a carryon? FWIW, this is a SWA flight. Bag check is free.
