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

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

The captain was amazing and kept us informed throughout that there would be some rough air. The flight also got delayed but we were able to actually leave on time, which was great.

The staff did not do a good job of getting everyone boarded quickly, so we missed our take off window and had to sit on the tarmac for 20+ min waiting for our turn. The plan was old. Pockets on the back of seats were torn and tearing off. One of the attendants was rude-she would ask a question but he walking away before you finished answering so she kept getting our drink orders wrong.

1 flight cancelled Had to fly out of different city Flight at new departure city was delayed 3 hours causing us to miss connecting flights. By the time we did make it to Prague our luggage did not. Had to wait day and a half for luggage to be delivered. Customer service was not good. Agents did not arrive at gate until 5-10 minutes before boarding

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

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.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Boarded early, left early, arrived 40 mins early! A win win for me!

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our 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.

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

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.

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.

Flight was delayed half hour before boarding, but when I checked flight aware the plane that would Pick us up had a delay of more than an hour. AA should let us know in advance to avoid waiting several hours in the airport

There was no inflight service. Once we landed we were delayed to find a gate for an hour and a half which was 1/2 the total time in the air.

It was good experience this time. The flight was on time.

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I am very disappointed with american. We have flown American airlines numerous times, as well as other airlines and never had such an experience. My son's flight for Sunday afternoon was cancelled around 11 am. We were told not to do anything bec AA would. After an hour of not seeing a change in his flight status. I called AA. I was on hold for half hour then opted for a call back. That call back never came. So I called again, in meantime I started looking online at my options. No flights were leaving that day from AA. But other airlines were flying out. We needed our son in Chicago asap.i kept calling AA for a callback, but never received one. Finally i called back later in the afternoon and a representative answered the call. She told me there were no flights out till Tuesday morning. I asked how this is possible, I had seen flights from AA and other airlines leaving Monday. She said she checked all NYC airports and there were no AA flights till Tuesday AM. Then I asked about getting on another airline. She responded i would be responsible for that. When I asked how AA would reimburse. She became nasty and told me AA has not responsibility to reimburse anything they will put me in a flight for Tuesday morning. When i explained he must be there Monday by 8am, she told me there's nothing to do and practically hung up. At that point I just asked her to book the Tuesday morning flight. I had this experience with other airlines, cancelled due to weather and they and their reps were much more helpful. Either way Tuesday morning flight was delayed as well. Over an hour! I expect more from AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

Our original flight was delayed and we almost missed our layover. Fortunately they delayed the second flight as well due to the number of people being on both flights so we got lucky. But it was due to mechanical issues which was frustrating.
