The Air hostess were very rude on my flight from Houston to Austin . Their regular communication itself felt a they are shouting at people.

The flight crew was extremely rude and especially not helpful when our flight was delayed.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

The flight in it self was good. The delays looking for pilots was unexpected.

This flight left late. We had A46/A47 boarding, but SW boarded 45 people from an interrupted flight ahead of us. It was a zoo. Seats are very uncomfortable, even for a 5’8” person of normal BMI.

The crew was very helpful, nice friendly. The only issue I have was the horrible turbulence that we experienced leaving Dallas love field airport. It lasted about 20 minutes I think.

Baggage check in would have been better if the service clerk told the other clerk that she was merging her two long lines of customers with her line so she could move luggage. Instead she only told the customers. When I told the agent and ask if she could direct who is next in line so we weren’t trying to cut in front of each other she said it’s not her problem and she can’t work three lines. I was shocked. Understood that they were working more than their share but some organization so the customers aren’t getting upset at each other would have gone a long way

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

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

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

The crew was nice but the people going to Orange County are so entitled. Everyone thinks everything is suppose for be perfect for them. Tough crowd.

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

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

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 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.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

did not have enough meal for first class passengers so offer us snack

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.
