Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

It was very difficult to stretch my knee out and I am very short. I also had a torn tendon in my knee which made it extra uncomfortable anyways. My husband is 6'2" and I can't imagine him flying in that plane.

Delayed flight, so I switched fights to SFO to Phoenix , Phoenix to DSM. Excellent service through American Airlines

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

The flight delay in Dallas created a domino effect that impacted all connecting flights, leading to an increase in the number of connections. As a result, I missed my flight from Casablanca to Marrakech due to the tight turnaround when landing in Casablanca. CMN Airport was understaffed; only one employee was available to assist passengers while others just stood by and watched. It was an extremely frustrating situation. Many passengers were crying and banging their hands on the counter while talking to customer service representative Allabough. Unfortunately, Allabough couldn’t change my flight in the system. At the same time, I was on the phone with an American Airlines customer service representative named Solomon, who said he couldn’t make the change either. So, I decided to take an ONYA Voyages train from Casablanca to Marrakech to reach my destination on Friday, June 26. It turned out to be an unpredictable trip.

They are still charging me after taking 466 and 833 for round trip from AR to to Bradley airport from 19 to 21. Then poor experience. Am hurt and I will say it on social media. Please stay away from this airline. I see in my bank account they are still taking 644. Am trying to stop it. I used to fly United airlines and I suggest that if you don't want extra charges and good service you go back there. American airlines delayed my flight again and I was late for my meeting, no recompensation but charging me over and over.

Pretty bad gate mgmt upon arrival. No open gates and we had to wait at midnight. Shouldn’t be a surprise that an aircraft is coming in.

Comfortable plane ride however on delays disappointment no real details as to why the delays when other flights are leaving the airport

They changed our Gate 5 times, and concourse twice. Changed our seats twice.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!
