The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

We were seated at the back and that was very uncomfortable for me with the turbulence we experienced on our way to Chicago.

I enjoyed flying on Korean Air. The service was great and the food was yummy. They served white fish.

I enjoyed flying on Korean Air. The service was great and the food was yummy, especially the bibimbap and cold spicy noodles. The only thing that bummed me out on this red-eye flight was that my seat did not properly recline so I was not able to sleep.

On time and flight crew are always so happy to help and always smiling unlike other airlines.

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

Stewardess are nice. Food could have been better and should have a better dessert. They do not offer scotch or beer. You have to ask for it. I also was not happy that you do not serve ginger ale and or cranberry juice. This is my first time that an international flight do not have this. I go home overseas every year and when I travel through ANA, Delta, Qatar, JAL, Asiana Air, United Air. they all serve this two very famous drink. You do not have a great snack tray.

You did not put me on a Korean Air flight! so I do not have nothing to say

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

Flight attendants rude, they disappear for almost 3 hours not doing rounds to see what people needed. The laboratories were full of empty water cups, because they never come back to collect them.

Flew on an Airbus 350-900. Excellent aircraft properly cleaned and serviced. Flight crew was excellent plane departed and arrived on time. The A350 has excellent air circulation far better than the 777. I would recommend Asiana to anyone looking to fly in a clean comfortable environment. This is my second round trip flight from New York to Bangkok via Asiana and I will book Asiana again!

I could not choose my seat prior to check in

I had the most wonderful experience from CEB bag drop through deplaning. The staff, the aircraft, food, and cabin crew were all amazing. I want to give a kudos to Marky from Mactan Cebu's Asiana airport staff for his exceptional customer service and assistance.

JetBlue's check-in was great, but there was an in-flight attendant who was very rude and unkind. I didn't realize that the bathrooms were already locked 30 mins prior to landing and needed to use the restroom. Instead of politely asking me to return, she rudely told me, 'NO, bathrooms are locked! Go back to your seat!' The JetBlue flight was more than an hour delay, which made me almost miss my connecting flight with Asiana. I understand the reasoning, but the action they took to get a hold of maintenance was time consuming. It took them more than 30 mins to get a hold of maintenance and for maintenance to get started. The Asiana flight and crew were wonderful, in general. They waited for us who were delayed from the previous flight before they took off and were very kind to take my checked baggage's info. Seats were a little uncomfortable for such long flight, but service and flight attendants were great! However, my 3 checked baggages are missing! They're lost somewhere in the transition. I'm writing this review 3 days after my arrival to the Philippines, and my 3 checked baggages, where my wedding dress is, are all still missing! I and the CEB airport crew have sent multiple emails to both JetBlue and Asiana, and neither has responded to any of our emails. Although, I was able to get in contact with JetBlue's Interline Department who confirmed that the bags were turned over to Asiana without confirmation details.

The full flat bed was not that comfortable, hard and lumpy., too much space wasted with those bulky walls and divisions instead of making the bed 3-4 inches wider. The compartment where you put your feet is like a shoebox, poor design. Toilets of A350 are just too small, sink is too small

Aside from a LOT of turbulence the flight was perfect! The flight crew was superb and the food was delicious!

The seats (legroom) are tight and chairs cushion is stiff (not comfortable). The crew was courteous, professional and friendly. There was no food / snack for this flight (very short flight, but still would be nice to provide some snack for the enjoyment).

FA were very great, plane was A350 new and clean

The crew attended to my needs and the foods served are delivious.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."
Pros: "see SH to GZ prior flight. The same."
Cons: "Same problems. Get KFC or McDonalds to cater. No one enjoys the airline's food which I suspect is prepared on a very small budget. Even a sandwich with a pre-packaged drink would elevate the foodservice."

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

How do you run out of beer after one hour of a twelve hour flight?!

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

2 hours delay on the 1st plane out of the day!!!!!

Multiple delays, with no explanation. Caused us to almost miss our connector. The airline made no effort when we arrived in Shanghai to help us make it to our next flight with the same airline.

Pros: "Price"
Cons: "Hotel provided was ok but I expected more . The wait to get to the hotel was way too long and people at airport were not helpful. There was no clear instructions on where to wait, who we were to deal with . The directions were misleading."
Cons: "delay of about 1 hour, we almost missed our international flight from beigin"
Cons: "Gate is crowded and no escalator only steps. No clear area for business class and its a fiasco boarding"
Cons: "The plane stopped at an airport between Shanghai and Kunming, which was not shown in iteneray. I got off at this airport thinking I arrived in Kunming. . I was told that I have to check in again at Kunming. When I tried to check in again, there was only one person in the entire airport checking in passengers and she spoke no English. We finally figured out what had happened and barely made it back to the plane before it departed for Kunming."
Cons: "Everything was great. Very nice and friendly crew, clean plane, great food. Excellent overall"
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."
Pros: "Crew was great and was happy to get gluten free food i could eat"
Cons: "Not lose my bags :("
Pros: "Very frustrated experience. Air China, air Canada, budget air, all push responsibilities away. Budget air got my name wrong, too, which would have caused me to not be able to get on the original flight from China anyways."
Cons: "Still I have not been able to get someone to fix my problem for me although I was promised that I could postpone my return flight by one day because of the delay at Victoria airport. Ended up having to buy a return ticket by myself."
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."
Cons: "Really old aircraft...please upgrade the video systems and make sure everyone has the same good optons"
Cons: "kayak charge me for seat assiment and kosher food and millage number Nom of those was in and i had to travel with out food and fight to get seats and make sure the millage number is in"
Pros: "na"
Cons: "no space to store carry on bag food, crew's service, delay to depart"
Pros: "Cabin crew was super nice and the exit row seating has large amounts of leg room."
