I was able to check into my flight through the app and online but had issues getting my boarding pass once I arrived to the airport.

I don’t like the music section but I believe it was a cost decision. I changed my flight last minute due to work issues and had to sit way in the back. The seats were way closer together than I would have preferred.

The flight attendant was very polite and attentive. The food was good.

Flight cancelled. Twice. And no communication. No gate agent. Went past boarding time and had to go and see email from AA. Airport communication was bad

It was so much better than expected, Ohare is not such a pleasant experience but American Airlines with the new, clean aeroplane and free Wi-Fi was outstanding and the crew so pleasant and helpful.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

Amazing I love American. I’ll never fly anyone else if I can help it.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

It was fine. I didn't love the food but it was at least a real attempt at serving a meal, unlike my earlier flight from Nashville to Dallas.

Crew timed out for a 7:20am flight. They had to fly another crew in. Didn’t leave until 3pm. Very poor communication throughout the day. Received a $12 food voucher and 8000 miles for compensation. Bags delayed in San Diego - came in on later flight. Delivered around 11:30pm
