Anything to make the customer experience better. Stop cancelling flights like people traveling have nothing better to do than have their life plans halted. People go to great lengths to get time off work, make plans at the end of their flights, make travel plans, go through the nightmare of checking in at busy stressful airports, make pick up arrangements only to have the rug pulled out from under them. Flying has become so miserable now!! The flights were delayed ONLY with American Airlines. The disorganization is sickening. After the flight being delayed multiple times, when the flight was finally broadcast that it was a go, EXCEPT, they were now waiting for flight attendants. They had plenty of time to plan this, what the heck?! Missed both connecting flights because it was so delayed. I vowed to never fly American Airlines again, did it and BOY was it a mistake!!! American Airlines ranks with United as two worst airlines.

late flight, no wifi, no entertainment, no snack. What are you coming to????

Missoula is a great airport. Desk and gate crews were very helpful and friendly

No communication with delayed and canceled flights. Completely in the dark for the whole experience.

The flight attendants were friendly. I liked that I got a mini soda can, not just a small cup. No issues with our flight departure, etc.

My wife and I had seats next to each other, but when our boarding passes were printed, British Airways had moved me away from her and refused to fix it. We tried to fix it at the boarding gate and were just told flatly "no". Never again.

Close boarding too early we’re willing to not let people on flight that could not check in. What ever happened to customer service? Three of us had to fight to get on plane shameful

On my trip from Seattle to San Jose it would’ve been nice to have the gate transfer nearby instead of at the opposite end of the airport that’s it

Personnel were helpful and caring. On my first flight I was seated near the rear of the plane. Before flight and after landing the smell of urine was strong. The nice stewardess tried to cover the smell.

Plane was supposed to leave at 5:40 left at 6:03 had to walk really fast to get to connecting flight just making the flight.

Requested an aisle seat at the gate and got it. The staff so friendly

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

It was close to its perfect the flake could be took off early, landed early, didn’t have to wait for my daughter stroller luggage came out quick, very efficient, very good flight

The amount of gate changes and delays is completely unacceptable. This has happened on 3 of 4 trips between Chicago and Dallas in 2026.

The delay update was very late. I had a stressful short connection and RAN through Chicago to get to the next flight, only to find the plane wasn't at the gate yet an nobody was boarding. I would not have had to run if the delay was updated earlier.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

Same the delay was not ideal and the credits to move flights was not sufficient

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

The crew were diligent about ensuring that our pet dog remained in his carrier for the entire flight, as is their mandate. I wish that mandate was changed so that our poor, scared pets can be comforted during a flight, whereas service animals get to stay out and about for the whole flight. Thank you.

first leg from san diego to chicago, only had cookies for snack. 1 flavor of sparkling water chicago to washington dc had option of cookies, pretzels, or gold fish. had 2 flavors of sparkling water. 2nd flight better however the best part was there was no delays!!! Got to chicago and washington dc early. That was wonderful!!!!

Mostly excellent. However, many too many gate changes. Connecting flight at ORD changed gate 6 times.

The flight from DFW to chs was delayed with multiple gate changes.
