AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

This flight was a superior flight in all regards. Extremely pleasant experience.

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

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

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.

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.

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

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.

Horrible like always, flight was supposed to be at 11:40am, we ended up getting a different airplane at 3:25pm.

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 got canceled 4 times, missed my connecting flight due to delays, have to wait to go home tomorrow

Third flight in two months where the crew was not there. Comfort seating does not guarantee overhead bin space. Passengers with children are allowed on the plane first - if you are flying to and from Orlando, this means half the plane has boarded before you get on. And somehow all the bin space is taken up. 3 out of 5 flights have had issues with equipment or procedure. Some of these instances caused the flight to be delayed because of a "nuisance" light. One time it was a bag that had been brought on board but did not belong to anyone so we had to return to the gate. Last night we were told the "AC" on the plane doesn't work well and we're 10th for take off- because the crew was late - and that it will get cool when we're in the air. Not sure if this is usual, but I didn't think flight crew could jump seat in first class. Movie and TV selection has not been refreshed for several months- flying one to two round trips each month easily exhausts the list of content.

Great experience nice pilot very soft and easy landing and take off

We sat on the runway for over an hour before departure. That was unwelcome.

Horrible. Faucet in sink not working, wifi not working. Didn’t bring food or snacks

Flight was delayed before take off and at landing. Baggage took 20 minutes. Flight crew would not serve full soft drink and had to ask multiple times before receiving water.

From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Flight attendants were great. Cheerful, upbeat and friendly. Jet, in particular, was fantastic.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

The plane was dirty, the seats were torn and broken, the service was the most terrible ever, the bathroom dirty, they will not even serve water you had to request it, the meals were terrible, overall less than Zero, I will never fly Cathay Pacific again.

Seat is too small. Food selection is limited and often ran out of selectable item.

Despite the crew's rough day, they were all very focused and friendly. The flight was too short for a meal, so no rating on that. Re. the AA app. It still isn't ready for prime time. AA works with Cathy Pacific for international flights to LA and the Aa jump to PHX. But the AA app can't find my trip and this can be problematic with flight delays and regatings at LAX.

Was not able to board flight because boarding pass name did not match passport name and no one caught it.

Had a bad experience with crew member coming back Hong Kong to la the person next to me one of the passenger have taken video and picture of crew member the person that served meal young kid late 20' s 6 5'10 had attitude at his peak anything I asked for I don't know if it was bad day or racial I felt humiliated as people could see difference towards me I no problem with Cathy and my whole family never had one was very disappointed

Frequently flyer number should and could have been put on at the time of booking as I gave the number when booking.

Very attentive crews Flight was very smooth and safe Only little disappointment was the slight delay of departure (~30 minutes ) which rarely happen with CX flights

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

Staff was very courteous. Plane was clean and quite spacious even in the last rows. Veg food could have been better.

Later on, when there was no more bottled water, the water we received had a strong chlorine/disinfectant odor. On my flight from Hong Kong to Los Angeles, there was a male flight attendant who had a mean attitude throughout the whole trip, and he was very impatient during meal service “Furthermore, we purchased a Hong Kong SIM card as part of our flight package, but we received no instructions—neither by email nor SMS—on how to activate or use it. Consequently, we were unable to use the service at all. We request a full refund, as this appears to be a deceptive charge

We used Kayak to reserve our tickets and specifically checked the luggage option which was a more expensive option. When we arrived at the terminal we had to pay an extra $90 per suitcase for the three passengers. This has been a pattern for the past 3 years. Why charge for a more expensive luggage option, and the ticket price not include luggage?

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

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.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Airline tickets are not cheap. You expect reliable competent service. Thanks to canceled flights and botched transfers we arrived at our destination two days late. This is not acceptable

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

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

This planes staff was top tier. Everything went great and had a great flight home.
