It was good overall. What I liked most was the restrooms. Compared to other airlines, the restrooms seem larger and look clean. The seats also look clean. The attendants are nice, except one time during the flight. I was sitting on aisle and a man sitting window. He asked an attendant for a snack. She told him to go ahead and get some snack from the section with food storage (I am not sure how it is called). So, I had to get up to let him get out from his seat. Why she did not bring him some snacks so that I would not have to move, I do not know... I was kind of surprised how inconsiderate the attendant was.

JOKE of a company with the most Ridiculous policies. JAL is amazing, KAYAK/UNDERPRICER is the worst company I have ever dealt with, NEVER AGAIN

Overall, a solid flight experience. Boarding was quick and efficient, even with a full and overbooked flight. The flight crew did a great job providing attentive and friendly service throughout. I flew in economy, and while the seats were acceptable, they could definitely use more cushioning, especially for a 14-hour flight. By the end, it was quite uncomfortable to remain seated. Legroom was also limited, particularly with a bag stored under the seat and the passenger in front reclining. That said, everything else went smoothly, and I appreciated the professionalism of the crew.

The flight was delightful overall. The check-in and boarding were on smooth and on time. Amenities and staffs were elevated. However, if glasses were served instead of cups, there should be a complete premium.

Sure I would’ve liked a little more space, but it was better than economy. I bring my own food because I have food allergies it would be nice if they offered larger salads or more vegetables instead of starch it was really a good flight. I don’t wanna complain. I’m grateful to fly at all safely. Thank you to the pilots.

Flight crews are very attentive and polite. Cabin and toilets are clean. Food is above average for economy class. We missed our connecting flights because the first flight was delayed, the ground crews at Tokyo were very helpful, providing all the information and support (including cash for our train ticket) to get us to our destination. Very impressive. No wonder they are always at the top ten lists.

Excellent! So happy that the crew members were so helpful and friendly and able to understandably communicate. They’re very receptive with someone like me, with disability. I love that I did not even have to ask for luggage help like, having to place and take down my carry-on luggage in and out of the over-head compartment. Hope, help is extended to disabled passenger(s) through out class classifications they’ve bought; economy or business class it might be. As a disabled person myself, I’m truly of great appreciation of this kind of help. Means a lot !!! Thank you so very much JAL crew. You out done others on this customer service part of the trip. Please continue to do so. From now on, I’ll choose JAL as my airline whenever I have to fly to any southeast asian countries. And I will disseminate my excellent travel experience with you to others.

American Airlines food is horrible. Also, paid to fly JAL on all segments, but received a much lower quality. I was disappointed to learn that we would be using American Airlines on this flight, which has less comfort, entertainment, choices, and lower standard of service. Overall not satisfied.

Food was very mediocre. Economy is pretty uncomfortable. Crew was excellent and responsive.

Not as good as I expected, I couldn't use the screen to watch movies or anything else because it wasn't 'STEADY' AT ALL, it moved every single time that the passenger who sat on that seat moved, that caused me fell dizzy and nauseous when I tried to use it, so I ended up with only sleeping and eating with no entertainment all my haul flight on premium economy seat, plus the passenger who sat next to me, she just loved to spread her very long hair down on my shoulder, face, arm, sometimes her hair just whacked my face till I really wanted to offer her my hairband!, super annoying 😑 and that my bad experience with that flight.

The food was terrible and totally inedible. If you are flying with ANA/United bring your own food it was a long flight to be hingry

I thought I bought the ticket directly through Kayak not a 3rd party

I like that we made it faster than regularly scheduled. Everything else was poor. The boarding was slow and chaotic. One person was screaming instructions to people that didn’t understand and there was only one camera so boarding was slow. The crew was not very friendly and one stewardess was extremely rude to everyone the entire flight. The food was not good and not themed to the country we were going to like every international flight I’ve taken. Lastly the seats were awful. After this flight I would never recommend United and will actively avoid booking another flight through them.

When I checked in, it printed two bag tags. The helper said they would cancel the other. They canceled both and my bag was left behind

It was really fast to Tokyo. Much faster than the budget carriers. However a lot less space than international flights.

The ladies are great seats should be a little bigger!

Couple of hours delayed, we had to re-booked our Shinkansen reservation twice. United Aiines need to improve their time!

The check-in started 3 minutes early; there were people lining up a half hour before. I was third, and I got checked in and passes in hand for my connection as well; I walked away from the desk one minute before it was even supposed to be open. Amazing. That said, the food on the first leg of my trip was not good, and I didn’t finish it. Second leg, it was tasty. You get a cup of Häagen-Dazs after dinner. The staff were polite and helpful. Will use again.

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.

Staff was friendly but couldn't find way to track them down during flight. Food tried to be gourmet but was just too unusual. Business class seats were hard. Even sitting on the pillow, was still painful. Have to give them credit for on-time flights and decent gate area.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Flight was great! This flight from Atlanta was even better than when I paid for Comfort from SNA to Atlanta.

Connection flights should be spaced out farther because too close I missed my connection.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

On time! There were plenty of airport employees who were able to keep us moving in the right direction. The crew on the plane were professional.

Left /arrived on time. Decent seat space. Like the wifi/plugs and entertainment. Windows and tray table were kinda gross. Attendants didn't start snack service til 40mins before landing. Two rows before us, captain came on to say there's turbulence and recalled staff to seats. So, no drink/snack. Later, attendants didn't stop to see if we had trash nor even look our way. Felt invisible! Almost all pilot announcements were not only unintelligible, but so quiet. We had no idea what she said.

Average seat comfort, a drink and chips were provided, early boarding because we checked a carryon at the gate was nice. Ticket pricing shenanigans, including fees to pick a seat, check a bag, and get food onboard - evidence the industry is reinvigorating last century’s strategies- destroys the experience before one ever arrives at the airport. It’s difficult to recognize any value or sustain loyalty in the end-to-end process making air travel more drudgery than pleasure.

Gate agent was unhelpful for handicapped boarding. Flight attendant seemed untrained.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

Smooth travel. Immediate update prior flight delay so I can arrange myself properly without too rush.

Everything was the best it could be. Crew found me with pre- ordered food. Excellent experience!

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

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.

The flight was delayed, they didn’t even have water for the toilets or for drinks

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

Very comfortable seating and the Flight staff were very attentive. The premium economy section that I was seated in was very clean, updated, and well appointed. I would highly recommend flying United Airlines as this experience was better than the Japan Airlines business class that I flew several months ago.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

The Air Canada AC1 flight from Toronto to Tokyo on May 16 was great overall. Service, crew, food and entertainment were all excellent and everything ran smoothly. We had emergency exit seats so legroom was amazing, but the seats themselves weren’t very comfortable and the plane feels like it could use an upgrade for a long-haul flight. Aside from that, everything else was perfect.

The plane was very cramped to point there was no way not to touch person beside you and a stewardess screamed at my son when I touched her arm to get her attention to let her know she forgot to give him his dinner when she passed him and gave a dinner to passenger behind him. Very inappropriate response and She never came back to apologize and other stewardess said she was sorry “if I felt” she was inappropriate. Horrible experience and she should be reprimanded for her behavior

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

Everything went smoothly — on-time departure and very organized boarding. We pre-ordered vegan meals, which were fine but not especially memorable. We may have had slightly higher expectations given it was a Japanese airline. It felt like a dinner meal than a breakfast. Overall, it was a good flight experience and we would recommend it.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

This flight with a lot empty place , and I have more room, feeling comfortable.

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.

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

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!
