My flight with Korean Air went quite well, I've flown with them for many years and have grown accustomed to their great service.

My flight with Korean Air went quite well, I've flown with them for many years and have grown accustomed to their great service.

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

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 💜

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

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

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

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.

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.

Flight arrived early, fantastic, since it is short flight, no food being served

They asked how much cash i have . I said no cash they said bring cash from atm . Why they even care about my cash.

Flight was scheduled to depart at 1210 hrs. It was delayed 1 hour 20 minutes (maybe for air traffic control reasons). The seats were worn out and very uncomfortable. Lunch was typical for airline. Flight free were friendly.

Pros: "Na"
Cons: "Over one and an half hours delay - sitting on the airplane"
Pros: "Lots of movie options, the food was good (had multiple food dish options for each meal)"
Pros: "Good and pleasant service, new plane very clean including regular WC cleanups"
Cons: "Boarding could have been done in groups"
Pros: "I would like to never fly through China again"
Cons: "I had a 9 hour layover in Beijing and they still couldn’t get my bag on the plane to Seattle"
Pros: "Everything was great, service on flight was really nice."
Cons: "Transferring suitcases between 3 flights was not great, with security check etc. Would fly with them again. Anytime, no hesitation."
Pros: "I had a very bad experience on checking in. I went to check in at Beijing Capital airport over 1 hour (about at least 65-70 minutes) earlier than the time of taking off on Nov. 2, However, I wasn’t allowed to check in. The staff said I was late and asked me to spend extra $200 to reschedule my flight. Therefore I had to spend $200 on changing my flight to next day on November 3, which was one day late back to Boston than I expected. That’s too bad and incredible!"
Cons: "There are a couple of things need to be improved. First of all, the food were not fresh, especially the salad dish. In mean dish, the beef cooked with too much dark source and tasted salty. Hope you could improve the food quality near future! Secondly, the luggages came out too late. All passengers had waited for their luggages for more than 1hour, which was really too long. Please consider about the concerns! Thanks!"
Pros: "New aircraft used like their 787-800s"
Cons: "Since Hainan is a Chinese airline, a lot Ig Ygritte move and music choices are Chinese, but I wish they had more non-Chinese content and choices"
Pros: "For the price, Hainan is a good value."
Cons: "I find that hainan just isn’t as “polished” as perhaps other air carriers in Asia are such as Cathay, Thai or Singapore"

The flight was cancelled. I wasn't informed where to check in, how and when. It wasn't easy to get in contact with Cathay service representative, and they were not very helpful... The staff on the airport - Air Canada (I assume) were the most helpful, kind efficient, patient... Thank you for all your help and care, for your patience, for your professionalism!!!

Great, the flight attendants were very friendly and the food was also good.

The overall flight went well and the aircrew was pleasant.

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

Not good. Flight was purchased for my father who needed medical assistance to board and transfer due to a heart condition. No one at Hong Kong from Cathay was there to assist and he barely made the connection. When I talked to him he could barely breath and was not sure he was going to make it. Really poor service even though the ticket stated he needed a wheelchair assistance.

The boarding experience was as expected and went well. The plane's economy seating plan is not designed for a positive customer experience but rather for company profit. When the passenger in front of me reclined, the distance from the screen to my face was the span of my hand (thumb tip to pinky fingertip). There is no such thing as personal space in this setting. This results in the domino effect, for when I recline the person in back of me reclines and so it goes. This is not to say that reclining is the answer as the experience is not increased, but simply managed.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.
