Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

Service and the plane itself were terrific, but the extensive delays both before we left and after were a real pain.

It was good and there is nothing to complain about .

The seats were narrower compare to other airlines traveling to Asia, which makes them uncomfortable after 6 hours The plane was worn, my tray table wasn’t level, You had to pay for WiFi and no Bluetooth option to use your own headphones. The crew was excellent in servicing the food and drinks. However I felt they needed some extra hands to serve the two sections of economy at the same time. They run out of one of the food option as they got to the rear section of the plane. Having travel on other Asian airlines during this trip; American Airlines can learn a bit from them, but I wonder if their service is geared towards a clientele that has become accustomed to not expect to much from an airline.

It was just a short flight. The crew was nice. No major issue.

Overall, it was ok. The attendants are nice. It was a short flight, and I did not use the restrooms. What I was frustrated was the check-in. I was to fly from ATL to Chicago (American) then change to Japan Airline to go to Japan. I checked in, but I only got a boarding pass for the flight from Atlanta to Chicago. It said I would need to check in for a flight to Japan on Japan Airline site. When I tried to check in on JAL website, it said I need to check in American... It was very confusing.

The crew was great, food was good. My concern is about the plane itself. It wasn't super clean, and during the landing process (after attendants had to take their seats) the air conditioning vent above my daughter's head started leaking a lot of water. It leaked for about 30 minutes, until we landed. I let the attendant know about the leak as we were getting off the plane, and she was very kind about saying she'd look into it. Given concerns about hygiene on planes, plus the fact that my daughter had to hold the blanket over her for 30 minutes to avoid getting soaked, that was not a great situation.

Absolutely WORST experience I’ve ever hard NEVER buy your airline ticket through a third party website, especially this one. Basically stole $1300 from me and has the WORST policy taking a WEEK to change a name on the reservation? A complete joke of a company.

There was a problem with the maintenance so missed the flight from las vegas to L.A and then L.A to Narita with japan airlines. They took care of the problem by rebooked with cathay pacific airways.

I paid for premium and it’s wasn’t what I was told I would be getting. Food wasn’t good. Should be able to pick and not be served items you dislike. Very little leg room.

I am trying to select a seat during booking but it respond that set assigment will be given during check in, and the seat assignment they give is in the middle seat and 2 row from the rest rooms, i am the person who pee a lot in this case I disturb so much the person beside me ,this trip is from Haneda to Texas, the trip from Texas to Cvg is a much better because its a smaller plane few passenger

I enjoyed the flight, but a little too much turbulence on the flight. Thank you for the meal and entertainment. This kept my kids entertain during the flight. I have to admit comparing the crew from ANA vs United, there was a sense of more accomodation, friendliness and service compared to United crew. I felt for the United crew, it was just a job and it can be seen in there demeanor and delivery.

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Choice of movies dated as with the screens. Major room for improvement on the software to sort and select choices.

Although the crew was eventually very good, they complained loudly about EVERYTHING before the takeoff. Did not set the stage for a good trip in business class. The western meal choices were pretty mediocre as were the wine choices. We took an ANA flight to Tokyo and they were outstanding!

As usual the flight from AUS in Austin to SFO was late because they didn’t have adequate staffing to board the plane on time creating a 1 hour delay, which resulted in me missing my flight to Osaka due to a missed connection. When I got to the gate 10 minutes late after landing exactly the time the connecting flight was taking off, I saw my flight to Osaka sitting at the gate and that gates had closed. I attempted to contact United Via chat on the United App and was given the runaround and passed between 2 separate “agents” who after saying they could rebook me, told me I needed to go to ANA even though they’re partners and all of my ticketing was through United. After going to ANA’s gate at SFO to try and get help I was told I would need to leave and go to United’s ticket counter in order to get help. The ANA agents said that it was United’s issue. An hour after running to try to make my flight I got to the United counter. I showed the agent my itinerary and she helped as much as she could. I was booked on a flight that would occur 13 hours after my original flight to Osaka and given $45 in vouchers which doesn’t cover much at SFO. I had also spent 30000 miles with United to get an upgrade with more legroom. And that was not refunded to this point. Ultimately I lost 1 whole day of vacation in with my wife and kids and, the 30000 airline miles and I’m out the money and time I spent. In these situations United and their partners should go out of their way to communicate and accommodate but I was left to my own devices to find the right resources. The only option was to fly to Seoul 12 hours and take a connecting flight to Osaka: I am a United Skyniles member and would not recommend booking a flight with them unless you thoroughly understand the routes as it is likely you will be left to your own devices to resolve the situation.

Staff at gate and crew on plane efficient and friendly.

I liked the flight over all. Towards the middle of the flight. There was a flight attendant who felt like they were rushing to had out vegetarian wraps and said they were “sandwiches”. She also handed out hand we wanted the water but she was walked so fast we didn’t get any. We sat in the seat 45 E & D. And towards the last 30 minutes of the flight there was an announcement saying the crew would collect trash. No one ever came around. So held on to the trash until we landed and left in the seats.!

Crew was fantastic. Seats were not completely lay flat but still comfortable to watch a show. International food was lobster which was very big but a little tough. The scallop appetizer was delicious. Loved the individual air conditioning vent at each seat. Flight overall was very smooth and very good.

As always, there is that one or two flight attendants that could be better.

I loved everything about my experience!!! The staff were absolutely incredible. I can not wait to fly again with them.

Checking bag at terminal was horrible. No agents to check us in and only 1 kiosk working. Boarding went ok. Crew onboard was very scattered rained. Missed our row while serving and then didn’t see them hardly again.

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

I flew from Santa Fe to Denver to catch a flight to London and the transfer of my luggage on arrival at Denver to the London flight worked perfectly. The crew on the ground and on board for the London flight were so friendly and efficient.

It was a short flight so I was expecting too much

Late- that’s what United does best. Missed my connection, rebooked to a flight 17 hours later and had to spend $500 on a hotel. What did I get? A $15 meal voucher. What can you get in an airport for $15. I hate United so much.

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress

One crew member, Brandy was very helpful with recovering phone lost in customs. The plane was ancient and poorly maintained. Checked baggage did not arrive with flight. Almost missed flight because if insanely short layover time. Air Canada is worst flight I have ever booked with Kayak. Wanted to charge for headsets for on flight media.

Plane was ancient, poor seating, layover time for flight to Raleigh was insanely short and total disaster, plane arrived in Vancouver late, luggage did not arrive in Raleigh with Raleigh flight. I lost cell phone in customs because of rushing to catch next flight.

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

gave me complimentary food as the flight was not full and was attentive to my needs

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

The flight was smooth, the plane was spacious and clean, the staff was kind and the food was decent.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

The cabin crew was professional and there were plenty of movie choices, but the food was a bit sub-standard.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.
