There was no beverage service and the only time I saw a crew member walk through the cabin is when we were preparing to land.

There was no beverage service and the only time I saw a crew member walk through the cabin is when we were preparing to land.

Our flight was delayed 3 times and this is why I am giving such low reviews. Everything else was okay but being in the airport at 4:30pm for my initial flight at 7pm to not leave until after 9:30pm is insane,

Flights were constantly delayed. CRW took 50 minutes to get bags

Flight has been delayed every time I've ever taken it. Seats uncomfortable. Children behind me yelling the entire flight. Some of this is out of their control but overall just consistently not a great experience.

Check in was rough because the check in crew did not know how to manage my international visa documents. Required a long process and 4 people to finally be able to proceed to security. They told us incorrect information several times before acknowledging we did indeed have everything we needed from the start.

Where do I start!! I was delayed with my flight from Dallas to Tampa. On the way back from Tampa to Dallas the flight was delayed over 4 hours+. I was put on another flight that was also delayed but not as long. Traveling on American Airlines is becoming exhausing.

There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.

The gate got changed several times and the flight was delayed over an hour. Awful experience

Poor communication ahead of time about flight delays and old planes/other equipment.

The flight was delayed multiple times. I was autobooted and placed in the center seat in the last row of the plane.
