flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

Flight got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

We departed and landed early which was a nice surprise. The boarding process was slow.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

The WiFi was not working. That made for a long flight.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Flight was delayed due to crew being not on time

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

bulkhead seat had very little legroom - even in bsiness class.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

Boarding was effortless, the food was outstanding, the seats in Premium Economy were extremely comfortable, and the staff and crew were excellent.

We had a cancellation due to weather, but the American Airlines staff was very helpful. Once we got on a plane, the trip was great.

I couldn't hear all of the announcements. It was nice when they put them on the screen.

Our boarding and flight was very good. However when we landed and pulled in to the gate it took 55 minutes for the jet bridge to be positioned next to the aircraft. That caused us to miss our ground transportation and it caused us unnecessary last minute transit planning and expense. Our flight was AA1733 on March 17, 2026

I liked boarding the plane. The staff were rude, the food was appalling and the chairs the most uncomfortable I have ever experienced

One of the best Qantas business flights I've had. Quality product

Much better than I expected for such a long flight.

It was nice having space in the way back where it thinned out with passengers, most folks in the far back were able to lay down and sleep. That was a pleasant surprise. Made the 15 hr flight go by pretty smooth, watching a few movies and resting. I had previously never used an airplane toilet, but finally used one. It wasn't too bad. All workers were very helpful and friendly. Their hospitality was welcomed as well

We were seated in the furthest back row of the plane. Our seats seemed to be the only ones that didn't recline, and our seat row was also closer to the seats in front of us than any other route. I'm a tall man, and this made the long overnight flight extremely uncomfortable and near impossible to sleep on. There was nothing indicated in booking that this row was tighter than the others.

We were downgraded from business class to premium economy with no advance notice. The staff at the gate were extremely rude, the crew on board not very interested in our comfort, mostly stood in the galley and talked with each other. The food was about the worst I have had and the portions were small ( and I am not a big eater). altogether sbout as disappointing an experience as is possible

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.

My flight was delayed twice. The first time because of “plane maintenance” and the second because the previous flight who supposedly “arrived early” took an obnoxiously long time to get off the plane. Total delay was over an hour for no reason. Not to mention your airline repeatedly changed our gate from one end of the terminal to the other. Not very happy about this experience. My previous flights with American haven’t had this many issues.

We’ve had a year of delays with American, and this one was another flight to add to that list. It just reduced our vacation by a day! So frustrating. In-flight entertainment (TVs) weren’t working, There was no drinks service due to delivery issues.

2 hours delay on my flight causing me to miss my connecting flight. Cause was for maintenance. I understand maintenance is important but maintenance should be done before boarding people!

This flight moved Gates several times in a short time period, from B to C, which required a substantial walk or rail ride. Then the flight was delayed more than 2 hours and the food was subpar compared to other flights.

Flight cancelled. Twice. And no communication. No gate agent. Went past boarding time and had to go and see email from AA. Airport communication was bad

I love the e fact that the staff communicated swiftly when my flight was delayed and gate number changed

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 .

The boarding process went very quickly, faster than I’ve ever seen boarding occur. I understand the need for efficiency, but the groups were called so quickly that there was a lot of chaos at the gate and people running through the airport. Then we all sat on the plane for a while, which seemed silly.
