The first economy rows have remote space in the seat which eats in the seating space. The seats are also smaller compared to other airlines.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

My seat was sold off to someone else. Had to wait 9 hours to catch the next filght. Definitely will never use Cathay Pacific again. Bad, very bad airline. will comment on google reviews too.

The coffee in Premium economy and economy is terrible. That's it. Everything else is great

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

The aircraft was slightly newer but the food was very bad. Bland and uninteresting. Nothing special at all.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
Pros: "The price"
Cons: "Staff was not helpful and kind of rude unless you spoke their language. Food options were terrible and not very comfortable seat for 13+ hr flight."
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The crew was okay. The seating was great on all except for one leg."
Cons: "On one leg, it must have been an older plane, because the business class seats barely reclined."
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."
Pros: "Boarding was a breeze, flight attendant onboard we attentive, choice of food orders at least two (in business class, can’t speak to first or main cabin passengers.) Flew from LA to Tokyo. Coming back from Hong Kong to LA. Fantastic flights, will use them again."
Pros: "The fare was good."
Cons: "More modern equipment. Tv screens. Movies. In flight magazines in English."
Pros: "The crew was super helpful and amazing! Comfortable seats and plenty of space for someone my size to sit (5’4”)."
Cons: "The only thing that I think could be better is the entertainment. I had a hard time figuring out how to use the screen on the aircraft but the selection of shows was good."

Better food and more space in the seats. Also when doing the web check in both times I was going in to your site the minute you open it and there is not really many seats to choose only to buy!!!

It was ok, not as good as it used to be. The Heathrow connection was a disaster - complete anarchy, unknowledgable and skimpy assistance and signage. Gate crew at next flight was great, held the flight while my wife struggled through security.

It was great! The seats were comfortable, and they fed me during the transatlantic flight, something which I have been missing out on for the past 3 years as I travel to and from school.

The seats were uncomfortable. It was an old plane. The crew could have been more hospitable.

This flight was cancelled at the last minute. We were rebooked on another flight but a day later. We lost a day of our vacation and paid for a night in a hotel we couldn’t use. The flights we were rebooked on (both American) messed up our seating on both flights-we didn’t get the seats we had paid for. All in all, a terrible experience.

I declined a wheelchair in Vienna as I was told it was a short walk. However, though I "boarded" the bus first, I was at the back when we got to the plane. There were steps up to the plane and no-one helped except the stewardess as I was near the top of the stairs. She found a better seat for me also.

Horrible connection in Heathrow on flight to destination. Flight missed due to delay on incoming flight. They did rebook us, and then that flight was delayed 2 hours. They don’t post gate info until 45 minutes to departure time which can cut it close if you have to take a tram to your terminal gate area. Then our return flight was completely cancelled. They notified us at 4:30AM. They rebooked us on a different airline and a different fare class. We were completely screwed. Travel day ended up being 30 hours. I will never fly them again.

Lost our bags in Heathrow, We didn’t receive bags in Mallorca for 3 days, out of a 7 day cycling vacation. Really inconvenient and disappointing!

There's no inflight entertainment, plane was old, power USB didn't work

We missed the flight to Barcelona because the flight from Baltimore was delayed. We flew on Vueling VW6653. Our luggage didn’t arrive. Please help us get our luggage. We are staying at Hotel Gran Via in Barcelona
