Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

The plane was dirty and the in seat air wasn't blowing as planes usually do.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

the seat was not padded at all - uncomfortable after a 3 hour flight

This flight was of course delayed because American cannot have flights that are not delayed.

I sat at the airport all night from 8 pm until midnight. The airline kept delaying the flight. They also kept moving us to different gates - 4 times. Then they told us we didn’t have a pilot so we had to wait. Then they cancelled the flight at midnight! I ended up having to rent a car to drive home. So i ended up not even being able to fly on the flight i paid for. Ridiculous, and no agents could help at all. I will not ever book this flight.

Mechanical delay > Crew Time out. No communication to passengers. Crew time out was positioned as a surprise (even though it must have been know at the time of boarding that the crew would time out.

Upgraded to first class. I would consider the first class on that plane to be only slightly more comfortable than coach. Long delay.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist

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 .
