They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

The flight was on time and very quick, as expected, but the leg room isn't great in coach seats.

Just a typical domestic poor flight nothing more. There is no food choices in such a flight. Crew doesn't really care if you are on-board or not

long flights are difficult but the crew and amenities made it a very good experience

Our seat row plus one ahead and behind we're completely overlooked during beverage service...

Need to have space for Cary on when traveler boarding any zone

When I selected my seats, it showed row 29 as the front row, so I paid extra to sit in what I thought would be the front row, but when I boarded the plane, row 29 was the second economy row. I was disappointed that I'd spent almost $100 more for no actual benefit.

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

When booking the flight i picked it because it said flying with ana even on our e-ticket as well but I showed up to the airport and I flew with united. I have flew with both airlines before and I prefer ana for the food quality and comfortable. So I was disappointed in that outcome and felt the food gave me minor ibs. The whole thing was missing leading with not getting what I thought I was paying for. Felt a bait and switched. Do not have confidence in using this app in the future trips

This was a large plane with an upper deck. It seems like business was upstairs. If it was a US airline then I would say I sat in economy plus, but I think it was just economy. Though since ANA would not allow me to choose seats for the price it may have been plus. Lots of movies to choose from, and good service.

This was the best airline I’ve ever taken. The staff are amazing. The food was great. The pilot was phenomenal. I would highly recommend this airline.

There wasn't much entertainment for my short flight but the onboarding process was smooth and the crew provided wonderful service. The seats were also reasonably comfy. Great flight.

I had to get rerouted because the weather delayed my flight enough to miss both of my connecting flights. I select nearly 2 hours on customer service trying to get rerouted and had to miss my first plane which took my luggage to San Francisco. Luckily, customer service sent me to the same airport but I had to ride 12 hours in economy after I paid extra for premium economy. Totally sucks that I overpaid. Customer service and airplane crew were great and really helpful though. Although I still hate how small the seat was, especially since I'm smaller than average, I can't imagine how much it would suck for an average sized person.

Flight attendant took good care of my mom as she boarded on and off the aircraft from her wheelchair. I did not care much for the food nor the movie options Available. I appreciated the increased legroom available in economy. This was one of the main reasons we chose the airline. Overall, the good value and I would fly again.

Cabin crew were excellent in taking care of my mom as she boarded the aircraft from her wheelchair. Did not care much for the food served.

I stopped flying with United back in the nineties. Today's experience reminded me of why.

Wonderfully pleasant experience. Good meal and beverage selections. Professional air staff.

Seats were comfortable with excellent legroom. Meals were also quite good. The cabin crew were excellent and very helpful. The check-in experience was also very smooth.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

Very noisy and careless crew on this overnight flight. They should understand customers want to sleep

Everything was fine and I have no complaints or things to note.

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

Highly impressive. On time. Smooth and fast boarding and disembarkment. Really great service

Overall, it was ok. However, the food was very sub-par.

The economy seats are much indeed roomier. Meals needs improvement.

flight delayed 45 mins - missed connection - 1 hr layover became 8 hr layover waiting for next flight -

Fast boarding flight on time boarded plane back to front instead of stupid zone groups like US airlines do...

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

leg space better than expected. two washrooms for one plane isn't enough.

My suitcase was completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

The boarding was relatively quick, the crew welcoming and flight uneventful. The omission of meals on all airlines is unacceptable especially when the flight is during a mealtime such as this one, (lunchtime), is unacceptable.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

Everything was made rather simple, so I appreciate that. All the people I dealt with from entering the airport in Jacksonville to my lonnnnnnng walk to my next gate in Chicago were excellent and very helpful.

No Charging ports for personal electronics, which were required to use wifi entertainment.

Crammed in like cattle waited 30 mins for late connecting flight (flight didn’t wait for me for me when I missed my connection at 2 different airports on outward journey)

Rushed, the boarding was a great deal like a Chinese fire drill.

Staff was friendly helpful also good timing I rate it a 10 out of 10
