Premium economy seats and food we're very nice although the price could be more affordable so we can do it more often.

Premium economy seats and food we're very nice although the price could be more affordable so we can do it more often.

mechanical issue, so delayed take-off (hence the low boarding rating) and made a number of people miss their connecting flight. Also took a long time to get our checked baggage. I luckily made mine with 5 minutes to spare, but it was nerve-racking.

Time to upgrade those planes so you can provide first class.

The flight was smooth and on time. Entertainment options were lacking and there was no food, other than some very boring snacks.

A better selection of entertainment would have been nice. I found nothing that appealed to me as a middle-aged traveler. The flight attendants were gracious, helpful, and attentive. It also would have been nice to have more bathrooms as the flight was full and the plane was big.

This flight was the second leg of a trip that began in Auckland, New Zealand. I was unable to find a way to select seats in advance. The boarding passes we were given in Auckland did not have seat assignments for the second flight. There was no way to check on it until personnel showed up at the gate in Los Angeles, immediately before boarding time. The flight was overbooked by one, and since I was traveling with my sister, we needed two seats. We waited in considerable anxiety for everyone else to board and when one person did not show up, we had to take whatever was left. At least we finally got on the flight although we were the very last to board. We were not able to sit together, of course.

The Premium Economy seats were very comfortable and the food was quite tasty. I did not use the entertainment system, but I was able to charge my phone and tablet with the seatback connection.

We had difficulty checking in as United didn’t recognize the confirmation number and the agent was not helpful. We went to the United Assistance desk where the agent was able to process our reservation. We also weren’t allowed to choose seats in advance.

Couldn’t request a vegan meal somehow but I noticed other people getting them

Carring crew, nice ambiance of the cabin, comfortable beds, good food well served. We liked everything.

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

Great food and good entertainment options for the long flight.

Loved the food and beverages available, spacious economy class, excellent entertainment

Very good overall. Highly recommend for all flying to Australia

We had bulkhead seats in a A380 in the upper deck in seats 31 D and E. Storage was very limited other than in overhead bin - which is not within reach when in seat. Yet paying same price as others in premium economy who have a lot more storage within arm’s reach. Seems very unfair.

Good check in and helpful staff. Delayed for 1 hour. Took about 45 Mins to get baggage’s at DFW . Food was average ( Hindu meal ) . Overall it was good experience

When I originally booked this flight, I was expecting to travel on Qantas. When the itinerary changed and the long-haul segment was operated by American Airlines, we were disappointed but remained open-minded. Unfortunately, the overall service experience fell far short of expectations. This was a long-haul international flight. Getting up periodically to use the restroom or stretch is inevitable, especially on flights of this duration. However, each time we stood up, we felt as though we were inconveniencing the crew. The tone and body language often suggested that we were in the way or disrupting something simply by moving about the cabin. As a result, I avoided getting up as often as I needed to and was physically very sore upon arrival. Meal service was similarly impersonal. The options were presented in single words “beef or veggie,” “pasta or beef” without any description of what was actually being served. There was little engagement or courtesy beyond that. Even simple expressions of gratitude were often not acknowledged. I am accustomed to no-frills travel and do not expect luxury. What was disappointing was not the absence of extras, but the absence of basic warmth and professionalism. On a long-haul international flight, small moments of courtesy and humanity make a significant difference. In this case, the experience felt transactional and dismissive rather than welcoming. I hope this feedback is taken constructively, as there is a meaningful difference between efficient service and indifferent service.

Business seats not as comfortable or private as most competitors (e.g. Qantas was outstanding), and movie selection was much more limited than Qantas or United has been recently

Hard to move and get out of my seat when the passenger in front is in recline position.

Poor! This flight was delayed 14 hours. There was no assistance in helping customers find other routes to their destination, nor any other kind of support. It was a chaotic experience. I'm not likely to fly with AA going forward.

Requested for warm or hot water because of throat pain, it was denied. The entertainment system was hung, requested the crew to turn it off, instead of turning it off they rebooted the device. It was stuck again, no one bothered to check.

Horrible on the chicago end. They change hates then there is a plane at the new gate so we can’t pull in. Then that plane has mechanical issue and needs to be pulled back to the gate but we can’t get to another new gate due the other plane being in the way. Horrible gate management which will cause many customers to miss connections.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

The employees seemed impatient with their guests. It seemed like they were giving us orders, instead of easily assisting. Our flight was delayed waiting on a flight attendant. It was alright.

My easiest trip ever. Flights left on time, and came in a few minutes early. The flights weren’t full so it was very comfortable. Thank you United

Quinoa chocolate cookies are my favorite! Would be nice to have internet service like American

Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!

Old plane, no amenities. Very abrupt landing. Unnecessarily long taxi time.

Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

No problems other than no seat back entertainment. Everyone was very pleasant

No notes; this was an excellent flight that was quick and comfortable!

Snacks and drinks should be served together and air hostess was not supportive with no smile which was kind of disappointing.

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

Bad service as well. Another 3hr delayed flight from chicago to Charlotte.

Very bad service the way back we was on the way for r two days very bad condition and waiting for luggage till now

United had no (zero) record of our flight. It took over an hour of us standing in line with surly employee while others waited to get resolved. I have never experienced such poor service and poor empathy.

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

No food on 4.5 hour flight, wi-fi did not work. Terrible experience for a long haul flight.

The crew were diligent about ensuring that our pet dog remained in his carrier for the entire flight, as is their mandate. I wish that mandate was changed so that our poor, scared pets can be comforted during a flight, whereas service animals get to stay out and about for the whole flight. Thank you.

first leg from san diego to chicago, only had cookies for snack. 1 flavor of sparkling water chicago to washington dc had option of cookies, pretzels, or gold fish. had 2 flavors of sparkling water. 2nd flight better however the best part was there was no delays!!! Got to chicago and washington dc early. That was wonderful!!!!

Business class flight attendant was very good. But our flight was delayed two hours for a “mechanical” bathroom issue that literally took 5 minutes to fix. Our plane landed early from its previous flight but still waited for a mechanic to show up to fix an obvious minor issue for almost three hours. This caused us to miss our connecting flight. They put us up in a Days Inn that was 17 miles away from the airport that took a half hour of driving just to get to and this was at 11pm at night. Then when we finally got back on a plane after a full day delay they left our luggage back in the airport. This was an international flight, so no luggage or belongings after flying 8 hours to a different country. We will NEVER fly American Airlines again.

12 hour wait in pdx to my initial flight to Dallas to hunstville

The flight from Chicago to Orlando was delayed inordinately. My whole journey from Lansing to MCO took 9.5 hours is just annoying and frustrating. We can understand the delays may be beyond their control, but overall the journey was so much waiting until reached to MCO. This is NOT the first time for me - but at least 80% of the time in this route. I barely remember reaching places on time.

I was truly shocked at how poor this flight went. The crew was not friendly during the checking process. The asked for people to gate check and were rude about it. They didn't handle my luggage with care. When I got to my seat I noticed a large section of the ceiling vent area was, no joke, TAPED TOGETHER WITH CLEAR PACKING TAPE! To add insult to injury, the back rest button was disabled on my seat and all the seats I could see. The wifi, never connected for me, despite troubleshooting it for a while. I did everything from restarting my wifi/phone to forgetting the network and restarting the app. But that didn't stop the mandatory 2 ads from playing every single time. Even the bags took over 45 mins to arrive at the carousel. Everything about this flight was a flop and I am beginning to notice that some of these events are becoming a trend. Perhaps it's time I switch loyalty programs.

Horrible airline, will never buy another ticket with the airline or Kayak. They close the gate 2 hours early in Kenya, I had to buy a new ticket and get a hotel room

It would be helpful to be able to download an eticket from either American airlines or Cathay Pacific; not just Cathay Pacific.

Another American Airlines flight, another significant delay. At least this one wasn't canceled like many others have been. This time we sat on the runway at LaGuardia for 2.5 hours. By my count that is 7 American flights the last three months that have been delayed 2 hours or more or canceled entirely.
