Just having a little bit more legroom would've been nice.

Just having a little bit more legroom would've been nice.

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.

Cabin staff were very disengaged, spoke with no eye contact, dismissive. Disappointing compared to my United experiences.

awful delay, awful communication, zero updates throughout the experience of a giant delay

On Time. AA is late due to maintenance all the time.

Flight attendant super rude demanding I remove my carry on baggage from overhead and place under seat. I stated I am an ADA passenger and need the leg room as the seats are very tight. That’s why I boarded early for the extra time to get situated. She said, we need the space. I replied “How can that be as only a few passengers have boarded so far? I am executive platinum status so I understand the rules and you are discriminating against ADA federal law. Please stop”. Her answer… then you should find another flight! Not ok. Addressed with senior flight attendant. So unprofessional and discriminatory.

Flight attendants were pleasant and helpful. Pilot gave fair warning about turbulence.

Unfortunately the flight was delayed. On a positive note the status updates in the app/text message were good

We waitied for 2 hours for flights to take off. Make us to seat 2 hours in small space is not good.

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 .
