I feel like the American Airljne seats are a little larger in coach and have some extra leg room compared to other airlines. My daughter suffers from Poly-arthritis so the extra room helps her to feel comfortable while on a long flight.

Seats from Santa fe to Phoenix were tiny. Very comfortable Phoenix to Ontario, even though I had a middle seat.

United NO entertainment screen, freezing air on the floor, removed the cup hole, scratchy thin blanket, bathroom much smaller, blue lit up ceiling difficult to sleep, service call button LOUD. Thanks American for having NONE of these inconveniences.
