Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

Same as already mentioned. This was more comforting as I got my aisle seat for my knee.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

Initial booking was confusing and had to get new CC issued.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

My flight was delayed. I was rebooked twice and even the second flight that was additional connection in London was delayed too, so I ended up spending more than 24 hours flying between four different countries and to be honest I’m not sure whether I ever want to use this airline again. My luggage is still delete. It’s been more than 48 hours now so to be honest, I’m not even sure how to describe the level of frustration I have.

I would love the entertainment center to be updated with more content. The flight to Doha had more options than the one to Miami

The luggage problem I previously mentioned was actually this flight

The flight was delayed due to snow in Frankfurt. There wasn't much information from BA or the airport, but Kayak was great and kept me informed of the delay and gate changes.

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

The seats were comfortable. So many empty seats allowed for stretching out and sleeping. The onboard entertainment was pretty good. The cabin crew were so kind and kept the passengers well- hydrated, and well fed.

We had American Airlines on our return and it was confusing if we were going with Aa or BA I had 2 different flight numbers and didn’t get our gate until it was boarding. So we were a bit nervous as the which it was

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

Economy seats were good and spacious. Much better than virgin by a mile.

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.
