Delayed couple hours due to airplane maintenance issues, we boarded and then asked to unboard, but cmon!! Can they do the whole maintenance prior to boarding?

Boarding was horrendous! Took absolutely forever… and the delay from the broken coffee pot was really kind of ridiculous

The flight was over an hour delayed. The problem was they had the wrong aircraft at the gate, Joe in the world does that happen?

Delays and multiple changes in gates. In accurate info sent to phone. Worst flight in years. With no apologies or recompense.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride. At boarding, the staff could have more pleasant even though it may be an intense time.

WiFi was not working from pos to Mia…. As well as they rushed us to the gate as if the flight was already here and leaving shortly when the plane never even arrived and took off until the scheduled time so then why rush us to the gate and have us thinking we will miss our flight.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

When you pay for Premium Economy on an 787 and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

My first time flying American Airlines, my first flight to CLT was wonderful and flight attendants was nice and had great customer service. My second flight from CLT to NY was very delayed due to whatever reason the crew was not greeting other than that I’m rate 8 .
