My boarding passes were pulled from my Apple wallet and my 3 family members who were all sitting together in the same row all got put middle seats and were one of the last to board and barely were able to get our bags in the luggage bins.

My boarding passes were pulled from my Apple wallet and my 3 family members who were all sitting together in the same row all got put middle seats and were one of the last to board and barely were able to get our bags in the luggage bins.

Everything went smoothly from the transfer from Orlando to a quick board. Flight was not full and we were able to get underway a little early. My only critique is that in Orlando, they offered active duty service members and veterans to board ahead of their zones in the initial boarding process. They did not offer to veterans in San Diego. Both flights were comfortable

Terrible experience with an extremely obese passenger seated directly behind me - who snored and gagged so loudly, even throughout takeoff, that no one within ten rows could have gotten any rest even with earplugs! I get that this poor person has a serious health issue, and that Alaska (maybe) had no way to prepare in advance (though he did occupy two seats). Still there must be a way to take a six-hour flight without feeling like I'm next to a roaring grizzly bear.

It might not have been their fault, but there was a two hour delay due to weather. Then we boarded and were about to leave when they said there were more problems at the destination, took us back to the gate where we had to fully deplane. But then five minutes later, they said everything was fine and to get back on the plane. This was the part that pissed everybody off.

I'm tall and the seats do not have a headrest so its hard to get comfortable. Staff and checking were all great.

I was surprised by everything. The cleanliness, the punctuality, the friendliness of the crew… and the Wi-Fi! Please keep up the good work.

Good flight overall. Lots of bumps during flight but pilot kept searching for smooth air

The gate agents begged us to check our carryons. They BEGGED us, over and over, and said that the flight was completely, totally full, and said that if we don't check our bags, it will cause huge delays. They finally said that "group suchandsuch will be required to check bags!" So I checked mine. Well, the flight wasn't close to being full, and many of the overhead compartments were *empty*! Moreover, my bag was delayed at the carousel, and it wasn't on the carousel that was posted. COME ON, AIRLINE, you can look at the seating for the flight on your computer and decide whether it's really necessary to beg and beg and beg people to go through the hassle of checking their bags! This is annoying as hell and makes me not want to use your crummy airline ever again.

A gluten free option I could actually eat would have been nice.

On this flight there wer only 25 people on board. So no one in 5 rows ahead of me and noone in 7 rows behind me. So very chill.

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.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

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.

Wifi was spotty. Tray table was very dirty when I sat down.

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.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

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

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.
