Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

The seat seemed roomy, the service was good, everything was fine.

Was realllly smooth. It was delayed but we were well informed.

Connection coordination with Star Alliance partner could be better. Lots of check in setup was not interlinked between operators.

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

Haven’t used United in a while. Was surprised with the free blanket and earphones. Service was great. Huge plane. 9/.row.

Delayed by 2.5hrs any longer and they would’ve had to honour their own policy for breaking their own rules and regs. Not cool, especially when I have an infant child that needs to stay on a routine and they get schedules.

Great thanks - a whole row to myself. Good food but film selection not great.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I liked the duration speed while in the air but that is is for positive things to say. The service was over 3 hours late, staff not very friendly (probably because they were also late to the destination), uncomfortable seats and disappointing food options

RE Food: Wish there was a choice for No Rating. Flew from Honolulu to Los Angeles on a Red-Eye flight (11:00 pm to 7:30 am). Other than a package of cookies with a beverage choice offered soon after take-off, and a beverage choice shortly before landing, no other food choices were offered. Everyone slept or rested for most of the trip. Nothing to rate. RE Entertainment: Everyone was sleeping most of the flight. Only saw one passenger watch about 30 minutes of entertainment on his iPad. I never attempted to access any entertainment options.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The boarding process was such a chaos with everyone crowding at the gates. There was no structure. The onboard crew were fantastic and very good.

For coast to coast travel the A321 and even the NEO, even in first class will never be excellent. That would take a B787 or 777 to accomplish.

The flight crew was fantastic! Which the seats had a small TV.

The foot ottoman cushion was missing on my business class seat.. the hydraulics is on its last leg & seat cushions do not have support or paddling. Heavily dented by butts

I have been flying with American most of my professional career. But the airline seems tired and becoming more and more subpar with older planes than other airlines, dirtier and less comfortable seating, and less and less amenities. Their WiFi seldom works and their food is becoming more and more mediocre. How do you fly from LAX to PHL with only being offered one drink and as a platinum customer. I am exploring delta here on out for more of my flying.

Was very unhappy with the entire process, from check in to boarding to the comfort of the flight. Did not enjoy the flight on Level.

Overall a great. However, the seating is way too narrow, for guys with any shoulder width. Luckily the crew moved the guy next to me, or it would have been miserable.

The staff on our flight from Charlotte to Boston were very friendly.

Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.

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.

The flight staff was excellent, one of the best I've had. Food and wine was very good and seats very comfortable. Luggage came out pretty quickly too considering the number of passengers. Also, excellent internet. The only thing that could have been improved on was the choice of movies -- kind of limited and not great selections.

The plane was not well maintained. The entertainment system didn’t work properly, eg moving map. Many of the seat controls did not work. Cabin temperature fluctuated considerably during the flight. The seat allocated was poor, it was noisy and offered no privacy. The perfume in the toilet triggered severe allergies. Crew was very goid.

Seats are too tight. Small space for long flights very inconvenient.

The flight was delayed over 3 hours and at the gate, we waited for an hour to start boarding. The gate lack of communication with the passengers was atrocious and when asked they even said they didn't work there and were just standing in for someone else so they couldn't give us an information about the flight status. The crew did not offer blankets, pillows nor headphones.

I originally chose two aisle seats for my daughter and myself in the same row. We got seated in the middle, three rows apart. Both of the men sitting in front of us reclined their seats fully leaving us NO room. A totally uncomfortable flight for eleven hours.

Liked - efficiency of boarding with 2 jetways. Checkin was with kiosks with helpful and plentiful workers to help with the process. Munich airport security was very automated, efficient and effective. Free wine and beer! Cons - food was only okay in economy class. Plane bathrooms could have been cleaner.

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Crew were professionals. However, the plane seats are too small -essentially there is no space to move around which for so many hours is almost inhuman but certainly unacceptable. Same with the bad quality of food and the fact that you need to purchase Wi-Fi

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?

Great crew dealing with the most unprepared family with a million kids and zero sense.

We were disappointed not to be able to buy out preferred seat from date of my original booking, which was about 40 days before the trip. When we arrived in Hannover on the Oct 10 I tried every day and the weed site said I have to wait until ck in, did that and still was not able to. Get to the airport and out seats were separate from each other. The crew was able to get seats together, was not the most comfortable. Don’t understand why this happened.

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

It was good but I wished if they could have sign do not disturb if we did not wanted any meals . I was tired and slept through the entire flight and woke up just before landing .being hungry Too late to ask for something to eat before exiting the flight . Left feeling hunger 🙁

Pleasant, attentive and efficient flight attendants. Boarding process and seat selection easy. No internet on transatlantic flight. Extremely uncomfortable, rigid seat.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

I was disappointed with the quality of the food for an international flight also I wasn't given a toiletry bag which is customary in international flights.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced
