It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

The wheelchair service is useless. They live you in different spots, not tell you anything just wait. I waited 30 minutes in Frankfurt when decided to walk the 25 minutes distance. In Budapest nobody came.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

Terrible because it was cancelled due to volcanic ash clouds in Guatemala while all other airlines kept flying. Had to pay for a hotel to stay overnight in Houston and try to fly next day.

Overall we had a good experience during our flight from San Francisco to Houston.

The crew was very kind, but no in-flight entertainment monitors and a 2 hour and 30 minute delay was extremely frustrating.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

It was good, the staff was great, and the food, was as usual, tea and biscuit. Bathroom was clean, and the plane was clean as well.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

I was able to get the AA customer Service desk to put me on an earlier flight without any issues.

The seat was comfortable, the attendants were very nice and WiFi made my life so much easier with work. Kudos!

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.
