Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

I initially boarded in a very comfortable and large plane and was told there was a mechanical issue with a waste receptacle. We sat on the plan for a good few hours, then were told we can deplane and that we would take off shortly. Delays continued and four hours later my flight was cancelled, and I had to quickly rebook another. The flight I rebooked was also delayed, and I when we boarded, I wound up on a small plane in a middle seat for the 6-hour journey and it was extremely uncomfortable. No issues with the staff in any way, just the overall experience of the delays, cancellations, and downgrade in comfort on such a long flight. It is significantly impactful on how you feel post travel and I was exhausted and sore from the experience.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

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.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.

Confusion at boarding with my seat (there wasn't one) that I had to have corrected using my status; then because of that had to check bags. And then a very long delay on the tarmac with no air conditioning on a very warm day. It was just a miserable experience all around.

Flight was delayed which isn’t the airline’s fault, but the communication around it was terrible. I left the lounge to show up at the gate to board at the time in my app, and the flight in front of mine was still boarding and the inbound plane hadn’t even taken off yet. Delays were slow to show up in my app. Improved communication could have let me have a more pleasant experience in the lounge vs waiting 1.5 hours at the gate.

We had to de-board do to maintenance and there was ZERO help with getting rebooked. The flight was delayed by over 24 hours. Quite ridiculous. When I. called Kayak to get help to rebook, they said they couldn't and that it had to be done at the American counter that didn't exist without going outside TSA security, which I did.

I spent 12 hrs getting home and had a direct flight that should have taken no more than 3 hrs. The first plane has an issue, was on the plane for over an hour before we had to deplane and move from A19 to A39 to board another plane. Boarded that plane to wait for another 45 minutes for it to also have an issue where we had to deboard. After everyone had went to get something to eat the food vouchers came out and half of us could not use. We then had to wait until 8:00 pm to board and finally got to Columbus Ohio at midnight. We were told that our luggage was on baggage 5. I waited 30 minutes to then realize my luggage was on 4. No notification sent. Horrible communication and I have a priority status.

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

I think since I am an AA Advantage member, my checked bags should have been free, but I paid for all 4 of us.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

A little late at the start but all worked out well.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist

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