very bare bones flight no entertainment screen, download shows prior to boarding to watch on phone or tablet.

It was good. It’s been a long time since my wife and I fly any where and things have changed. Our trip was to see our new grandson. We fly economy and that was not good for my bad back. It was a quick flight but uncomfortable.

Service in first class no longer exists on American Airlines .

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

Delayed due to no crew. On a major holiday travel day.

The flight got canceled last minute with no explanation or refund, I had to rebook for a different day

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

from Boston to Washington was good but return to Boston was terrible, Gate was changed and plane was so uncomfortable, I thought it would crash 🙈🤦‍♀️ also when I showed my bording pass they didn't know where to send me and finally gave me direction and at the plane they said to find free seat somewhere😬🤦‍♀️🫣

they should make XXL people buy two seats. sitting next to a person that was half on my seat and could not even buckle the seat belt, so I had to lean in the isle the whole trip.

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes
