The seats were really comfortable. Flight crew were friendly with passengers. Overall was a great flight.

Great crew, flight on time, luggage pick up a breeze

Delayed and took off even later than the scheduled delay time

Only issue was with seating. The economy fare we purchased did say there was no guarantee the three people in our party would be seated together, and we were not. At the gate, the agent told us more specifically, the fare we purchased meant we would be seated in middle seats only. This should just be made more obvious.

Unfortunately I was stuck next to someone who should have purchased 2 seats instead of taking up their space and mine. I couldn’t move the entire 3+ hour flight. Very uncomfortable flight.

More extra space was awesome. Even though I was on the first groups to board, bin compartments were already occupied by passengers seated on other seat numbers. That is unacceptable.

Crew went over and above to be helpful. Plane had mechanical problems that caused us to depart late.

The flight was excellent, I recommend people to fly with Delta

Another smooth and friendly flight. For a shorter flight, it was a pleasant surprise to see a decent snack and complimentary drinks.

When we enter the airplane there were many water drops falling from the ceiling all the way long to the seat , and when it departs were even more over us getting the hair wet , and later on was too hot , the A/C not work well.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

A long delay. Don't travel late in the day.

Awful. There was a minor problem with a fridge and they had us 2 hours in the runway before take off. The paper work alone took them half hour. There was no attemp to make up time up while in teansit and when we arrived, they had us another half hour in the plane because of traffic. I, and a bunch of people, lost their onnection flights for 5 to 10 minutes. Not even the attemp to wait given thar all delays, but the taxing, were United's fault. Then another 45 mins to get an agent and no flight alternatives for 2 days. Im am very disapointed with this "premium carrier".

Overall great. I was forced to check my carry-on backpack from EWR to BOS but it came out on the luggage carousel so fast I didn't even get delayed for my pickup.

United needs to figure out its Economy PLUS standards; its better than economy but that's not saying much. It seems like United stripped away all the basics for an international flight (such as In Seat entertainment) and repackaged some of them as plus. Would not fly United internationally again.

IT WAS A LONG TIME SINCE THE LAST TIME I TRAVELED. I THOUGHT I WAS TO BE LOST BUT EVERYONE WAS PRETTY NICE WITH ME AND MADE MY EXPERIENCE NICE. THANKS

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

I like the united App ,easy to check in and baggage.

United domestic flight was better than international flight. There was no switch to control Ac In international united flight. Food was also average,

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day. See attached receipt. https://share.icloud.com/photos/0f5ns2AaeIr7w6t_uH1qfPBUg

The hosts were very friendly and accommodating. The food was welcomed and very decent. I would recommend!

AA was a very good experience. The employees are wonderful

We had a very pleasant flight with very comfortable seats and nice staff.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

Seats in coach aren't padded enough for a 6 hour flight

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

the handling of my luggage. It was Lost or stolen At my destination.

The flight was 3 hours late taking off. The lounge experience in Heathrow was terrible. No charging plugs, no table busting, and very overcrowded.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that

Uncomfortable seats at row 40 A and 40 C, they didn’t recline. Also, my prior seat selection was not honored.

Good plane, excellent food, crew and entertainment. Seats in business could use an upgrade

Chair is very high. Your feet cannot touch the ground for 8 hours flight. It was a nightmare. Food was bad.

Moved the flight an hour later, were not reliable about confirmation, website didn't work, no gate information, boarding was a mad house. Flight itself was fine and short. Organization needs work.

we had a flight confirmed then we were called and told we didn't have a flight. I will never use Kayak for a flight again.

Very good service from San Jose to Madrid . Ryanair service from Madrid to Brussels 😕

The flight was decent. I purchased my flight through Iberia, traveling with my elderly mother with mobility issues. I try to pay for luggage and seats online prior but Iberia website directs me to AA website. AA airlines website does not recognize the record locator. My mother and I are separated and each get a middle seat. She is seated the furthest away from a bathroom. I had to sit behind her to see her wave at me to use the bathroom. Lights out on the flight and I could not see her wave and she is not tech savvy to push an attendant button even though I showed her how. The attention to this detail puts AA at the bottom of my list when traveling with my elderly mother. Bad execution and handling when servicing those with extra needs due to mobility. I could not get her to the bathroom because she’s slow and she had to wait for me to get up from my middle seat then move her out of her middle seat. She had an accident which required that I hel her clean up before taking her back to her seat.

Lost luggage, breaking the rest of plans, instead of going to other place from JFK should go home and wait for bag don’t know for how long 1, 2 days.

Business class was like premium economy, with an empty seat between my husband and myself. There was a curtain behind our head separating us from the next class. The person behind me’s knees were against the back of my seat, so I felt I shouldn’t recline at all. The person in front of me reclined all the way, then was out of his seat much of the time. He sat on the chair arm of the seat next to me, leaning into the aisle to speak to the man in economy behind me, placing his face about 6 inches from mine. Then he was off speaking to others on the flight, including the flight crew.

Overall was good except for the seat which, for an 8 hour intercontinental flight, was uncorfortable. For that kind of flight seats should have more space, even for economy seats.

This was definitely a no frills airline. The flight crew didn’t even offer us water, or anything to purchase. Even the coffee wasn’t free.
