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 staff is amazing, I cannot stress that enough! The food is really good and snacks at stations to take for yourselves. Economy seating is fine, not the most comfortable, but our friends in Premium Economy said they were very comfortable! Decent entertainment options, but being built in, you have to use their cheap headsets unless you have your own plug in ones. I only have Bluetooth earbuds.

It was good. The crew was efficient, food was good

Seats were extremely cramped even for economy. Food was atrocious. Crew was fine but no follow up, additional drinks offered etc. For a 14 hour flight I expected more.

Boarding was good. Inflight service was good. Alcoholic drinks could have been served free.

Suite lounge in Honolulu is the best lounge in Honolulu. I love the huge bathrooms in ANA first Class on the A380 Honu plane. Japanese meal was outstanding and service was amazing. Everything was just excellent. Can’t wait to fly again

Their was $200 charge for 2nd luggage, airplane very new and flight smooth. Flight time seem faster then Asian stoping Korea then china.

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

Missed our flight with Cathay due to late Westjet plane and chaotic Toronto airport. Had to clear customs get bags and re check bags in an hour. Did not make it got lost not clear signage with bag drop off. West jet only allowed 1 checked bag for this international fluid. Cathay checked my second bag for free.

Flight was kept super cold. I was shivering and had to layer up.

The crew and the food were excellent. The plane was kept quite clean.

More meal choice. There was only pork, beef and shrimp. I could not eat any of it and they had no alternatives

The only notable problem was bathroom facilities. Only one toilet for far too many people, and dirty nearly all the time. Both otherwise, Cathay Pacific is great. Wonderful staff everywhere.

Very bad. Flight got delayed and missed my transfer flight twice. Had to stay overnight in Hong Kong and the next flight booked was also delayed.i had the worst experience flying from Singapore to San Francisco. Lots of delays and rerouting.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

My seat had many issues. First the chair was broken where reclining was difficult. My usb plug was also broken so charging was impossible.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

Boarding on any airline is a hot mess. Load your pivilaged passengers, then back to front. Back to front.

Some crew were unfriendly or in some cases just straight up rude.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

A long delay. Don't travel late in the day.

Super friendly with lots of drink options an entertainment. Friendly crew.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

United Airline crews were very friendly and very attentive. 12 hours flight was gone like in a shorter one.

Delayed - weather wasn't bad at either end. Also sat on tarmac in ORD.

Food was surprisingly delicious. Space in the seat is horrible when the seating front is reclined. Movie offerings were terrible. Crew was friendly and helpful.

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

It was good that our flight left early. It was a nice smooth flight and landing.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

It was a problem because there was a delay where we sat before taking off from newark,then when landed in Toronto we sat on tarmac and they wouldn't let us out for a long period of time. When we finally were released to the airport in Toronto the attendant scanned our boarding pass that we were here for our connection to Brazil. We ran all the way to the gate and they said at the gate the door is shut so we can not let you on the plane. We explained that we were checked in by the attendant when we arrived at Toronto airport to go to Brazil and they should not have shut the door. We were ignored at the gate

Flight home was delayed multiple times, did not get home until 2am

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

My original flight was cancelled and then rebooked four hours later on a recovery flight, but I was checked in as stanby and had no seats so as a family of four we were concerned about not being seated altogether. Our flight then got delayed by another 1.5 hours and when seats were assigned at the gate, three of the four of us were together and we could get my wife closer, they offered no assistance.

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.
