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

Korean are so racist and when I ask question or directions they totally ignore me and say racist. Also they give me an rude attitude.

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 trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

This was an amazing flight. The crew was great. The service was great. The food provided was great.

Flight delayed going to Korea. No free WiFi. Other than that everything else is were good. I would love to fly with Korea airline again

Not very comfortable seated in the back plane due to turbulence

Attendants were very kind and frequently offered water and snacks. Food was excellent. For some reason, my IFE system would not play dialogue for any media despite my efforts to change to different language voiceovers, restart the system, etc. so I could not watch any videos.

Staff at gate and crew on plane efficient and friendly.

As always, there is that one or two flight attendants that could be better.

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

Vegetarian options were not that great. However, the crew and service was awesome

Entertainment was good , comfort on airplane easy hoarding food and drinks was good and a friendly and good service of flight staff

I was good seat to keep stretch my legs . but couldn’t keep my bag in my hand . because they told me can’t keep my seat is no holder , because no seat fronts of us. wish I can put my leg on something higher. but instead of that everything goood.

Good airlines btu ORL airport messed up the return flight for me. Checking out a connecting flight pax is unacceptable.

Although the flight was delayed because of the equipment came in late, I still give them excellent service ..good food selection and in flight entertainment were sufficient.. I will continue to fly with them

Staff was rude and loud. No respect for customers unlike the Starflyer Osaka to Haneda sector where service was outstanding. What a stark difference. Maybe United should learn from ANA how to do customer service.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

The flight was delayed going out of the gate at BKK that made it a difficult challenge to get through immigration transfer at tapei and make it to my departure on time. This appears to be a recurring issue. The flight crew and cabin crew were excellent. The food was very nice.

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Cramped seating for me. Luckily it wasn’t a long flight

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

long flights are never truly comfortable but the airline did their best. crew was great and the flight was safe.

The captain was amazing and kept us informed throughout that there would be some rough air. The flight also got delayed but we were able to actually leave on time, which was great.

The staff did not do a good job of getting everyone boarded quickly, so we missed our take off window and had to sit on the tarmac for 20+ min waiting for our turn. The plan was old. Pockets on the back of seats were torn and tearing off. One of the attendants was rude-she would ask a question but he walking away before you finished answering so she kept getting our drink orders wrong.

The go to HK trip will easily giving jetlag, but coming back to Chicago has no jetlag because of the time taking off matter.

The experience was very good. A little disappointed for the delays and the screen. The touch screen was annoying for being so irresponsive. Not a lot of good movie choices for me. The service is great. Food could have more choices though.

In economy, very cramped. Once the front seat was reclined it was almost impossible to get in and out of our seat. The personnel was excellent.

great experience. better than all other airlines flying this route.

Flight from Hong Kong to LAX was late, the plane was grubby, overcrowded and hot. I recently flew Starlux and that was a MUCH better experience.

The crew, pilots and flight attendants were all amazing. What could be better is reinforcing that seats cannot be reclined at departure and landing. I had a person seated in front of me who had her seat all the way inclined, including during take-off - after the crew asked her to seat upright. Cathay Pacific should reinforce this safety request and perhaps penalize those who don't follow it. I felt very unsafe with this person limiting my space and perhaps putting my life in danger in the "unlikely" case of an emergency.

They downgraded me from premium economy to regular economy and me had 2 major lay over and had to have an emergency landing due to engine failure mid flight Don’t use them worst experience I have ever had still dealing with the trauma

Just want to do a little more clean up so does not smell like urine.

Worst experience I have ever had with any airline in over 25 years.

Wanted different plane design with an additional bathroom at the back of the plane.
