Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

I was forced to check my carry-on backpack despite there being space - but it came out on the baggage carousel so fast it didn't even delay my pickup. Otherwise a good flight. Boarding began early (which was disadvantageous for me) but fine.

Overall great. I was forced to check my carry-on backpack from EWR to BOS but it came out on the luggage carousel so fast I didn't even get delayed for my pickup.

Boarding was easy. RDU gates can get crowded, be prepared to be patient. Flight was smooth, with excellent service. Pilots really provided a lot of visibility into flight details. Plane and seats were clean and serviceable. TY!

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

No food service almost missed because of first flight delays

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

My flight was delayed. They boarded us, then no sooner were we on the plane, they made us get off again and wait another 45 minutes before doing it all over again.

We were offered Flight Change due to overbooking. We accepted and chose an earlier flight. We went to Rebooking center to make the change but agent told us no changes permitted on our Basic ticket. AA should not have made the offer to change our flight.

Flight overall was good. Landing was a little rough, but could be attributed to the rainy weather.

Check bag location is full of rude employees who are unwilling to assist with issues after talking to AA on the phone and relaying messages. The boarding was good. While on the flight it got really hot. Asked flight attendant if there’s a way to drop the temp and make it more comfortable as we are flying from DC to Miami so flying from cold to hot weather. No changes made. Stayed hot and uncomfortable on the plane. When asked again about the AC being down the flight attendant said no the WiFi was down but not the AC. I mentioned it was still hot. No changes.

I was in a wheelchair and went from international to domestic. I was transferred to several different modes of transport and expected to give a tip at each transfer. I was, although, grateful to get to the gate in time for my flight.

They didn't have any gluten-free snacks, oddly, which I require...or any flavored soda water or decaf tea options, which seems to be standard.

The flight was great, and I have never ridden in first class previously so I don't have any practical knowledge of the norm. The flight out to DFW was delayed and I sat in economy which was as expected, not nearly as spoiled as I was in first class which had more general room but that is par for the course. I have no complaints and will wait until I fly American again before I can make a valid improvement. I will fly American again in the future.

The plane was very warm and the crew turned on the lights for the entire snack service.

It was okay. I opted to pay for an upgrade to an exit row, but this might’ve been the worst exit row experience I’ve ever had. - The fold out table was janky and didn’t fold out properly. - The seats felt squished together as I was the aisle seat in the group of three, but the guy in the middle felt like he was constantly leaning on me. - Everyone who walked by brushed up against me, or knocked my entertainment screen, to include the food and drink carts. Didn’t get one apology or excuse me. - The community flight tracker screen was right in front of me and was sooooooo bright I could barely catch any sleep on my 13hr flight from Seoul to DFW. Not the best experience at all…

There was a delay that affected all passengers with connecting flights.

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.
