Ring in first class for an overnight flight, there was no blankets nor pillows for first class customers.

I didn't like that my paid for seat was changed 2 hours before my flight.

Overall, a good experience. The food, however, was subpar. The breakfast was a joke.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Wonderful crew and early arrival to our destination. It was so nice to have free wifi access and movies too. Thank you!

Bigger seats. Board back to front! Disembark front to back!

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

Service in first class no longer exists on American Airlines .

My seat was very worn. Otherwise I had an excellent flight
