The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

The business class is excellent. I loved the food, and the crew was very attentive and professional. From boarding to arrival, everything felt smooth and well-organised.

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

Great service and comfort level. You can have more of vegetarian food options.

It’s great, long flight and arrive safe at destination

Everything was excellent as I expected. They also had a very caring crew. I had a headache and asked a Tylenol. The crew members kept checking with me how I was doing.

They were very accommodating of a dietary issue. Nice movie & tv selections. Non-stop helped get through a very long (15 hr) flight

everything was fine, would have liked better food but it was warm, great choices for movies

It was horrible. The flight crew was unfriendly and the food was absolutely horrible.

They texted me my gate number and then they texted me again it’s now boarding but in different gate, and the gate was so far from the gate they texted me earlier. I have to run just to get to my flight. They always do that.

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

I missed the flight. I never got on. That sucked.

Not very much of anything, it probably was once of my least favore business class flights I have experience in all the times that I flew Boz class

Terrible experience. Staff would not even refill my tea once. While they refilled a fellow Japanese persons wine 7 times. They also lost my luggage. Horrible. Go elsewhere

main courses of the primary meal were not good- the beef dish was really not good-

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.

Their in0flight movie selection is limited in size and poor in quality.

Everything was great, except the Wifi, but that's understandable.

I loved Ryuichi Sakamoto's OPUS in the movie choice.

Great service. Premium coach seat was uncomfortable. Food was non-descript.

The best way to travel a long intercontinental flight. Staff are kind, polite and welcoming. Passengers experience a comfortable low stress environment, Customers feel they are well cared for by a highly trained and professional staff. I will shout from the rooftops when I get back home, "Japan Air is the way to go!"

My boarding experience was so bad. While traveling from LA to HYD, the boarding was smooth. But the boarding experience from Hyderabad to LA was utterly poor and unprofessional and caused lot of anxiety and stress. Even though we were at the airport Boarding well in advance to accommodate for Immigration and Security Check, Cathay Pacific Boarding On Ground Crew has done a very unprofessional job. It is one thing to follow rules, but being inconsistent and not being able to communicate this clearly is wrong. I was not aware that my laptops weight in my backpacks is also counted against the cabin baggage. While coming from LA to HYD, the ground boarding crew didnt ask for this. They just checked the Cabin bags weight. But at HYD, not for everyone, but for some people they enforced this. Our Checkin Luggage was carefully weighed at home and was accurately measured to 23 kg, Now they asked to move all the weight in our Backpacks where most of the weight is from Laptops and tablets for each family member, I need to accommodate this ~10kg from 6 laptops in to one of the suit cases and pay extra for excess baggage at the airport boarding place. Without a weighing scale how can I accurately move all the items from cabin baggage to one of the suitcase. D Venkatesh is the guy who enforced this. But I dont have a problem with the rule enforcement, but the way he guided us in solving the problem. I was willing to pay the extra money for the extra weight. He told me that the 32 kg excess baggage is allowed with 150 USD. I understood that 32 kg is extra on top of the 23 kg chickin baggage. SO I pushed all of them to one suit case and then when I took this suitcase, I was sent back saying that he meant the total as 32kg but not the excess should be 32 kg, I had to go out of the line make these changes without a scale thrice like this. They literally harassed me. Noushad his manager was sneering at us. When I said, I am going to complain about this, my wife heard him saying some bad words in Hindi. You get one chance to harass your customer. I will never board Cathay Pacific again.

I’ve flown 2 better Asian airlines in the past year.

Good experience and I would fly again with CP. Disappointed that they ran out of the dinner option that I preferred. Other than that, the trip was quite enjoyable.

The crew could have awaken me to eat dinner!! I was so waiting to order the braised duck breast and fell asleep b4 crew got to me to take order. When I awoke, lights were out and food had been served without me eating. I did love the apple juice!

The flight was delayed for over an hour, which made me worry about pets in cargo.

It was good, on time boarding. Have a good service. .

Better food quality and suggest using the 777 for the HKG-BOS leg instead of the A330 since the seat pitch seems better on the Boeing.

I didn’t use entertainment But everything else was of excellent quality

The flight was delayed for 30 mins. The overall experience was good.

Flight crew went above and beyond to make sure the flight was enjoyable for us!

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

Flight operated by PAL. We boarded, and one engine started. The crew found some problem that could not be fixed. The flight was canceled. This run from yhz-bos is very unreliable.

My ticket did not exist when I got to the airport. I had to book another flight and was still charged by Kayak

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My return flight experience was one of the worst times I have had traveling anywhere this year. Not because of the flight. It was because there was not enough time allocated to deplane, go through U.S. Customs and U.S. Security to get to the gate for the connecting flight to Boston which I missed, There was well less than an hour between my landing in Montreal from Prince Edward Island to my connecting gate. I even called Air Canada on the morning of my return and noted my concern over the short layover time, not more that 45 minutes. The initial flight was four minutes late. I was seated in the rear of the first aircraft, and it took at least 20 minutes to deplane. The U.S. Customs was a considerable distance from the gate at which we landed. The need for double security seemed unnecessary and redundant. The distance from the security to my gate was again fairly great, and the wrong gate number was listed on my boarding pass. The agent I approached at the flight that was going to Newark, New Jersey was too busy to answer my question as to what gate was for Boston. When I got to the right gate, they had just closed the door to the aircraft even though I arrived a minute late. If I knew the distance to Customs and from Security to the gate, I would have asked for a seat on the next available flight which was 4:30 pm. When I made my call at 6:00AM that morning. When I asked the agent at the Boston gate, he said that the 4:30 flight was already “OVERBOOKED!” I was put on an 8:30 PM flight and didn’t get home until MIDNIGHT. I then had to care for a barnful of hungry animals and didn’t get to bed until 2:00 AM.

I paid for a comfort class seat and was seated in economy.

Very smooth flight and the crew members were very welcoming.

Crew was friendly and helpful; cabin seemed roomy even in economy class.

The flight was delayed but at least they let us know early about it (the night before)! Everything after that was smooth!

Air Canada was on schedule, fast, and took care of me the whole flight. With affordable price, I 100% recommend you fly Air Canada if you are able to.
