Good 7.2

Cons: The crew was not very attentive compared to other times I have flown business class. Not very solicitous in terms of offering water regularly, etc. Also, surprisingly little food offered over a 14 hour flight from Shanghai to New York. A reasonable dinner at midnight, shortly after takeoff, then nothing till almost 12 hours later, and then not the hearty breakfast one would expect after that much time and on business class but a very small snack. Not very satisfying.

PVG

Pros: Aircraft was clean and fairly comfortable with adequate legroom for avg height people, though tray and screen placement can be improved on.

Cons: PVG airport gates could deal with more seating, at least double... and better handling of delays.

Mediocre 2.3

Pros: Nothing! Couldn't be worse. The crew don't care about passengers and can't speak English either. We had a very long delay for no reason. The plane landed at a different airport that it was supposed to and then the airline bussed us to the Shanghai airport. Terrible terrible operation...

Cons: Everything! First please hire flight attendants that can speak English. Then provide better food. Even with Chinese standards the food had a bad quality. The stewardess didn't even understand that airplane mode exists for cell phones. She screamed at me to turn it off. Entertainment was a disaster

There was no overhead bin for the center “2” seas, had to share with the outer window occupants, but plenty of room.

Cons: My husband and I sat in row 30 (center & aisle). I sat in the center. As soon as the plane took off, we all heard a dog bark nonstop. The lady directly in front of me had brought a dog!! We felt terrible for the person to the lady's left and right. And then in the middle of the flight her dog pooped all over the floor! And the poor Stewardess' (they were SO wonderful) had to clean up the mess. Then the lady had to clean up more pee and poop and left all that mess right in front of my feet and handbag (which I put under the seat)! I had to hold onto my handbag and shoes the entire trip bc it was touching the pile of dirty paper towels! I couldn't eat the meal due to the gross situation, and I was very upset about this situation all bc of this one lady who had no regard for the ppl around her and behind her! I don't know what your policies are concerning bringing a dog on a plane, but it ruined my flight. I love Korean Air, and love the service and the stewardess' professionalism and attentiveness, but this has made me think twice about flying anywhere on Korean Air!

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
