Overall, very uneventful and pleasant experience. Most importantly, no delays.

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

Seems like crew assumed you're korean. Not impressed by crew

One of the flight was delayed. The flight attendant of returning flight to LA was mean.

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).

The legroom was great for a 5’11” person. The 11 hour direct flight had two meal services included in the ticket price which was less than other airline’s cost without food service (Canada air)from sfo to incheon. The airline is focused towards Korean nationals with the onboard entertainment selection of Korean movies but English subtitles were available. Overall premia air is a great option to fly from the US to Korea.

Most of them are OK! But, meals service was not enough. I felt hungry after eating the meal for the first time. I had to buy some other food. So I had to buy a sandwich and drinks for the return flight. And I am not sure it's only my feeling or not, I felt my butt is getting forward. I will use Korean Air or Asiana Airline for next time to visit Korea.

Plane and service were great. The entertainment is only for Koreans. Wish there were vegetarian options for food. All in all pleasantly surprised. Economy premium was quite good.

This form doesn’t work. Can’t type in, had to copy-paste. The crew constantly telling everyone about minor things is unnecessary. Did you put the belt on, push your bag more under the seat… The seat space was good for tall people, the food was decent for airplane.

Roomy seats for the given price! I couldn’t ask more!

Great airline, but there was no English entertainment (movies or shows)

Check-in was an absolute disaster, taking more than an hour and half because they offered no online check-in and Kiosks were not available to use. In-flight entertainment was exclusively Korean media with a selection of only 5 or 6 movies to choose from. Korean television shows were also available. The food was lackluster. My chicken and tomatoes had 3 small pieces of chicken next to a mountain of soggy wedge potato fries. The seats were more comfortable than other airlines I’ve flown with and the staff aboard was extremely pleasant and helpful.

One of our luggage items was damaged during our flight to Newark from Incheon. Although our email communication was not responded to, when discussing the matter with the staff at the Newark checkin before our return flight to Incheon, we were provided with a free replacement luggage item. This customer service was, overall, very satisfactory.

I would have enjoyed some hot tea, preferably green tea, but they only serve hot coffee.

10 Hours delay on departure of the return flight and in-flight Wi-Fi was not available entire flying time all that caused monetary loss to my business.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

We had a 2 hour delay. The seats were smaller than most other airlines. The person in front of us wanted to lay back and we had to stop her because she was pressing against my girlfriend’s legs. We had to ask her to sit up and not lay back due to the lack of room.

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Everything was fine once we actually got on our flight. It was more then annoying they canceled (delayed) our flight. We lost out on a day of our trip along with money on our stay. Plus we had to book another hotel. So expensive.

This flight was canceled and delayed several times without explanation. The plane was freezing cold and no wifi for messaging. Getting off the plane was terribly unorganized and felt like it took forever….

The flight was delayed several times without explanation. The seats were terribly uncomfortable and wifi isn’t included. All these make for a less than ideal flight.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

Terrible. I didn’t fly and I had an important meeting the next day.

Missed this flight due to the first AA flight delay

Equipment swap led to 2+ hour delay on international flight. And to top it off, boarding took forever.
