Boarding was great, and the crew were very friendly. The seats must have been a bit on the older side and you could feel some of the seat components through the padding. Also, the plugs did not work on the row's entertainment screen or charging ports. Checked bag was transferred for connecting flight, and we appreciated how early we had the connecting gate information.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

The flight was delayed, they didn’t even have water for the toilets or for drinks

It’s always a great time flying with united airlines.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

Excellent service despite turbulence during the flight. Flight attendants were remarkable!

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

Terrible boarding and first class experience. Nice staff but overall disorganized, dirty plane.

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

Early departure meant on time arrival. Only real problem was free internet had issues, although chatting with the internet help desk (you can do this via aainflight.com) got the issue resolved.

The staff and service on American Airlines were truly outstanding. I had requested wheelchair assistance for my mother due to her knee issues, and the team went above and beyond every step of the way—from boarding in Boston to our arrival in Chicago. Their care, professionalism, and attentiveness made the entire experience smooth and stress-free. I’m very grateful for the support they provided.

Found that the plane used for this short flight is smaller and therefore the seats are really squeezed tight.

Great experience. Good dinner and service. FA's were very nice and attentive.

Jill was the flight attendant in first class she was fabulous!! Best flight attendant I have had in years.!! And I fly every other week. Other can learn from her!!

Gate agents for boarding not trained. I am disabled have eyesight problems and was told “do it on line.”. Wheelchair unavailable in Dallas even though it was in my record

Everything went on schedule so I have not much to say. I was a bit disappoint with the breakfast choice - I did not have a choice as there was only one option left by the time the trolly came to my end and I could not enjoy it.

After boarding our plane we sat for 20 minutes and then we’re told we needed to deplane and board another plane due to a leak. This added another 2 hrs to our travel time and then we needed to board our long haul flight of 15 hours! Our seats were very cramped…was not expecting this for a long haul plane ride. Very uncomfortable. The drink and food service were not often enough to be able to stay hydrated. I have been on long flights where the stewards would walk the aisles with water to insure you were hydrated. The flight was a smooth one and the landing was exceptional.
