Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

The crew was very kind, but no in-flight entertainment monitors and a 2 hour and 30 minute delay was extremely frustrating.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

Got home at 3am after deboarding the plane. No compensation offered by American

Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.

The seats need better cushioning for a nearly 5-hour flight, it was a bit uncomfortable. I'm glad American has free wi-fi but there were was a bout 30 minutes in the middle of the flight when there was no connection which was frustrating.

My original flight got delayed day of so I had to rebook it from one layover to two layovers. The flight also left earlier which was a slight inconvenience but manageable. Then my first connection flight got delayed 3 separate times for a total of 2 hours delayed, causing me to miss my second connection flight back to Santa Barbara. Now, because of this missed flight, I am missing my college classes that I pay for.
