I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

My flight was delayed so bad i missed u it so i just said never mind

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

Gluten free snack options and meals that offer both gluten free and dairy free.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
