I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!

I fly coach so there is always the feeling everyone up front has more space than me. Everything was fine - on time which is the most important thing!

Great as one can be for a one connection 6 hour flight

On time, quick boarding, so nice of them to honor active and retired military with early boarding. Attendants were nice . Plane was clean. A bit crowded like all flights.

Everything was great except the fact that catering did not restock the flight from ATL to GRB and we were only offered water.

The WiFi on the plane was out. I also thought movie options were lacking.

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

My seat was changed without my consent. It wasn’t a major deal but annoying.

It was delayed over an hour and a lot of announcements disrupting movie.

Delta has joint the nickel and diming airlines. The experience is getting worst by the day. 1,000,000 miles for a trip to Asia in Business Class where I got the same thing for just under 90,000 miles through an Asian airline. Where is Richard Anderson? Please come back!

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.

Despite having numerous passengers held up by American Airlines delays. Qantas (an AA partner) closed boarding with 0 flexibility

Boarding , crew and meals were all amazing. Couldn't wish for a better LOOONG flight from Dallas to Sydney .

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

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.

Three aircraft in succession experienced maintenance issues, resulting in a six-hour delay. The original aircraft required replacement, and the substitute aircraft arrived more than two hours late. Passengers boarded that aircraft, only to be told later to deplane due to maintenance concerns. We then boarded a different aircraft that had arrived at the gate, only to be instructed to deplane once again because it, too, experienced maintenance issues. After hours of delays and two separate boarding and deplaning events, passengers were directed to a third aircraft departing from a different terminal and had to rush across the airport to make that flight. That was the only aircraft that ultimately departed without incident. Of course, passenger safety must come first, and I am grateful these issues were identified before takeoff. However, when three aircraft in succession require maintenance attention and passengers are repeatedly boarded before those issues are discovered, it raises legitimate concerns about American Airlines' preventive maintenance procedures and aircraft readiness checks. One aircraft with an unexpected issue can happen. Three aircraft in a row, combined with multiple boarding and deplaning events, suggests a pattern that warrants review. American Airlines needs to take a hard look at both its maintenance practices and its decision-making process for boarding passengers before determining that an aircraft is ready for service.

There was a 4 hour delay, some of which was attributed to ATC weather but started with maintenance and then later also log books. Though the flight went far beyond the scheduled time, there were no accommodations such as additional meal options or anything else.

Delay for 1 hour due to maintenance issue and late boarding

Had issues (application error) selecting my seat before checking in. Return Flight was delayed over 2 hours. Sat on the tarmac for 20 mins after landing Overall, not good of an experience compared to the times I have flown AA. Not sure I’m coming back.

Got to gate late and they made me check my bag but when I got on flight there was lots of overheard bin space .

The intuit carrier I have flown with that doesnt have WiFi available on board - at least not on the A380. Meal I wanted wasn't available and the meals I did get were all served cold to warm at best.

The flight was delayed and gate changed so that was not fun and the flight to Dallas from LAX was very delayed on Sunday. It was just not a great experience due to the delays both ways.

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 .
