Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

I had a good time. However, I paid for the wifi and it was in and out the whole flight.

3 hour delay…. Nearly 2 hours sitting on tarmac. Do better, United. Or at least have the sense to not say “we hope you enjoyed your flight with us” upon disembarking.

Everything except the food and entertainment. It was a great experience though

Flight was delayed from 35 minute delayed aircraft arrival to 90 minute delay causing us to miss international connecting flight on SWISS resulting in 16 hour delay to reach detonation causing significant angst, monetary loss and discomfort. SWISS transfer desk and staff was like robots not willing to help at all.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

Their app did not recognize my Aeroplan frequent flyer number and would not allow me access to my boarding card. Ground staff was readily available at the airport to print it out to me.

Excellent as always. Service was excellent and fully bilingual. Cannot complain .Will travel again. Always have and will continue. Highly recommended.

5 hours delay - minimum communication, no compensation, no support from Airline. Terrible customer experience

Our flight from Chicago to Des Moines was the problem flight due to a dismissive flight attendant. His conduct was unnecessary and unprofessional.. I will avoid using Americam Airlines again because of the situation. Very disappointing.

Aa cancelled my flight where I was in first class seat 4B. They auto rebooked me on another flight, did not give me a seat assignment until at the gate. Where I got seat 29f, for a 4 hr flight. No accommodation at all for my first class ticket. Left 3 hrs late as well.

It was delayed 5 hours due weather and your app should be rebuilt or disabled. I could not change my original flight on delta so I did it through the delta app. Then rebooked on American once delta cancelled all flights from LGA to PIT on 8/27. American Airlines was fine once the flight took off 5 hours later. I wish my company would find a better provider than kayak.

DCA-LAX No screen on a 5 hour flight (almost) no food for sale on a 5 hour flight (practically) no wifi coverage or speed on a 5 hour flight I should have gotten my money back, shame on American

The entire process could’ve been better. Delayed multiple times and American lied and said it was due to Weather in New York, even though other flights were taking off the entire time (including other American Airlines flights)

There were alot of delays without any information. First, my original flight was overbooked so I volunteered to stay back. The layover was hell, I sat in the airport for 4 hours. I was highly disappointed because no one was around to provide answers.

Crew and agents misguiding on tight connections, and lack of connecting crew looking for inbound planes. A very avoidable missed connection as a result.

The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.

My experience with American Airlines was great. Unfortunately my stroller was not located and has not been given to me and or reached out in return for in regard to information.
