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.

Flight was smooth and on time: however, this flight was filled with advertising. We got it over the speaker system both when we took off and when we landed. Flight attendants were handing out sales flyers when we landed. It was not a good look.

The first leg of my trip from Dallas to CLT was smooth from check-in to landing. The snack, biscott cookie really needs an upgrade. Even if the upgrade is a choice of the cookie or pretzels.

For super long flights Premium Economy is the way to go. But the lack of WIFI onboard (don't you think it should be free on a 14 hour flight?) and the sparse personal entertainment selection made this the biggest detractors. Also, can we keep that map from flashing in our faces the whole trip there? Jesus Christ.

Great for a small Commuter. Quiet and relaxing. Seats were better than most.

The plane was late getting to Ontario by half an hour which makes it inconvenient when you have people waiting for you.

I paid extra for what I thought was leg room and it certainly was not. I had a very cramped experience on my flight from Dallas to Detroit and it was the section right behind first class section. I did however have an amazing flight from Atlanta to Dallas on the initial outbound flight.

The plane left late and there were four gate changes. Fortunately they were all in the same terminal. The crew was truly outstanding. There were only nuts to eat due to the very short flight time. Beverages were as expected.

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 .
