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.

The food was not great; but I don’t expect much from airline food. However, the staff was incredible! I had gotten to the gate when I realized I had left my computer at the security checkpoint! I told a staff member and she said, “well, you will miss this flight if you go back to get it” It was a long way from the gate. I asked if I might get on the next flight. She sent for another staff member, and he took me to the gate desk. He found an open seat, and said,”okay, go run to get your computer, I will get you a new boarding pass.” I rran back, retrieved my computer, and returned to the gate. It was closed, but I found the gate nearby where the next ANA flight was leaving. Another staff member was ready for me, and printed me a new pass, and even made sure I still had an aisle seat that I requested! I got in line and continued my trip. These people are amazing, helpful, and friendly. My trip could have been ruined, or postponed at a great expense, but they saved the day! 5 stars!!!!

I originally thought I was booking with ANA airlines and didn't see "operated by United" until the day of. I even thought the United check-in update was a scam so ended up checking in 3 hours before the flight, causing separate seating and uncomfortable middle seats.

Very disappointing. Our flight was delayed for almost 6 hours with the lost time disrupting our travel plans. United should have known that any delay (approximately and hour) triggered a no-fly/work because according to the FAA they had to many flight hours. After the mechanical delay (approximately an hour) we had to wait for a fresh crew change. Seems to me that United could have anticipated this incident. Again, a very disappointing travel experience.

Excellent crew, food and comfort from LA to Narita. Flight from Narita to Manila was just okay, Food and comfort needs to improve. The business class was not comfortable.

Lots of leg room in premium. Departed exactly on time. Friendly crew.

Cabin Crew was excellent. They took care of everything requested. Flight was good

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

I love the comfortable business class seats. The service was excellent. Staff was friendly.

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Problems with entertainment system eventually rectified. Cabin crew attentive and polite but a bit absent minded when it came to remembering requests, salt, sugar etc.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Poor links to cathay meaning it's not possible to check in online or reserve seats. Incorrect information provided by cathay regarding check in and transfer at HKG. Delay in flight required is to be escorted / run to make the connecting flight and no opportunity to use the business lounge. Luggage did not make the connection so we arrived in Manchester with no luggage

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

Crew was very good, but could have checked on us when meals were not being served also.

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Business class seats felt very cramped compared to other airlines.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.

Both my flight where delayed Had 25min to make it to my transfer flight

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .
