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.

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.

Appreciate having multiple food options for allergies. Nice to have an extra seat between us for comfort.

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.

My flight was delayed. We left at midnight. I got to Greensboro (GSO) at 1am. All of AA's flights in/out of Charlotte always seem to be delayed or canceled. It took me all day on Sunday to get to my destination of Cincinnati from Greensboro. I had to be rerouted through Chicago because my original flight was canceled as the door to plane was closing in GSO. The saddest part is I could have driven and arrived sooner. . . I recognize there is a lot going on that impacts travel. This week it was weather. Yesterday in Cincinnati it was President Trump. But as a frequent flyer, the flight from South Bend to Charlotte always runs late. The subsequent flight to Greensboro is always midnight to 2am. . . I do want to give props the Charlotte boarding crew. They had four flights going out of the same area at the same time. They turned it quickly and mitigated the grumbling from the crowd.

Never going to fly your airline again if it can be avoided.
