If the service crew didn't make difference between people and they change my seat without asking me if is okay or not with me

The entire process could’ve been better. Delayed multiple times and American lied and said it was due to Weather in New York, even though other flights were taking off the entire time (including other American Airlines flights)

There were alot of delays without any information. First, my original flight was overbooked so I volunteered to stay back. The layover was hell, I sat in the airport for 4 hours. I was highly disappointed because no one was around to provide answers.

Great. Clean. Seats comfortable. Food was free. Had new release movies.

On time departure & early arrival. Made a long day much better.

The boarding crew was very helpful with a little special problem I had. The inflight crew - so-so.

They kept us on the tarmac for 6 hours after already delaying our flight by 2 hours. No one had any answers. They sent our gate checked stroller to baggage claim instead of giving it back at the gate.

Crew and agents misguiding on tight connections, and lack of connecting crew looking for inbound planes. A very avoidable missed connection as a result.

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.
