Not very comfortable seated in the back plane due to turbulence

Ford not that great the seat not to big for leg room like other airline

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 💜

New plane. Perfect gluten free meal Very flawless procedures from check-in to the landing. Taking off on time and landing even earlier and the luggages are already there after shortest arrival report.

I like your stewardess, they are nice. However, your food could have been better and wheres your dessert? You do not offer beer or scotch. I do not drink alcohol biut my husband can have one or two, he has to ask if he can have one. during dinner or lunch, it should be offerred. Also, you do not have the most famous drinks ginger ale

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

Going through security a third time to get on the next flight was again utterly ridiculous and unnecessary. We were in a International secure area once again and as far as I'm concerned should not have been put through the gears for absolutely no reason. The United States can get all the information they need from the travel itinerary, there was no need to be forced out of a secure area to personally interview everyone on a connecting flight to find out their US immigration status.

Going through security a second time to get on the next Korean Air flight was utterly ridiculous and unnecessary. We were in a International secure area.

Great service but food taste and options have gone down a few notches.

Excellent crew, immediate attention for any request. Both ways on time (rather before time arrival at Haneda). Only complaint was that the seats are not reclining like rest of the airlines that I travelled. The Backrest is fixed. The reclining is only within the box seat, so you slide down forward for reclining, not backward. So it was bit uncomfortable. The food for the day trip was excellent. For the night flight, no breakfast was served, only dinner, which was disappointing.

At least it was not very cold inside the plane. I noticed there was now a bidet in the bathroom and that’s good! I didn’t like the window seat. Flight was smooth except for 1 turbulence. Plane was on time. Thanks. Food was not that great. Miso and green tea were good! As usual movies were old and there were no changes.

The food was not that good. I liked the miso, green tea, and ice cream. I wasn’t able to put my carry on bag under the seat in front of me. The flight was smooth. Please expand your choices of movies especially the new ones. I can’t choose any of those films. They’re old.

Food as always. PA was not clear, especially the English ones. Very limited Hollywood movies. Unlike the first flight I had, this plane has less leg room and less room for my under seat baggage.

The Experience was fantastic, it's a quick flight so no entertainment or food. Just a refreshment

Again I paid for an upgrade on my credit card didn’t get it need a refund. . American I not good at gettin in contact for refunds.

-Bathrooms were regularly checked/maintained. -Food was okay, but the miso soup was good. -Top of my foot got bitten by a bug when I took off my shoes and was only wearing my socks. It was swollen and very itchy for several days.

Attentive crew, great service with regular rounds of drinks and trash collecting. Only complaint is the food, which was mediocre.

Liked the food. Needs improvement: 1) the flat bed was very hard and the set up was not at all passenger friendly 2) the announcement were impossible to understand even in English. 3) the flight information on the monitor was terrible it showed a airplane with no information like altitude, airspeed, heading. You could not zoom in or out to orient the aircraft to where you were in the flight. 4) movies were old and very limited as was the music selection.
