Entertainment was okay

On both flights my party of 2 was split, despite an early check-in. We were lucky enough to swap seats because ANOTHER family was also split between us on the first flight. On the second, 3 parties were all split in the 3 rows in front of us, so we had to shuffle 4 different people before take off before the majority of the people were sat together. On 10 hour flights, generally I feel parties shouldn't be split unless they're checking in later than we did.

The business class lounge in Seoul was very crowded with non-business class passengers. Not a pleasant experience.

I am very impressed with this airline since stumbling upon it by chance last year during our first trip to the Philippines. We were greeted with a bottle of water, slippers and toothbrush w toothpaste, a blanket, earphones on our seat. The food is excellent and they feed you often. What was most impressive is the level of service provided by all Korean air staff. The stewardesses take great care of the passengers, always smiling and looking sharp in their uniform even though it's 3am and they have also been up the same time as you have!

Our flight from Toronto to Houston was cancelled. The staff at the arrival counter was very slow and rude. We wanted to leave by the United flight which was leaving in an hour or so but the supervisor was not willing to do anything. We ordered Asian vegetarian food and it was horrible. Never again Air Canada.

Flight was cancelled on our way back home from Gudalajara, was speaking to a representative for almost 2 hours to get me on the next flight the flight representative forgot to put me on hold and told everyone how rude i was, i was not rude i was just trying to get home. The representative couldn’t help me so i asked to be transferred to a manager, after 2 hours i was transferred and the manager hung the phone up. Long story short i called back spoke to another manager Yana and she was the rudest lady ever! She basically told me for waiting to long i will have to be placed on a flight 2 days after my cancellation flight. I started to cry because i needed to be home and she basically did not care so i took the date. Never again and i will warn everyone about this airline and their customer service!

The servers were very nice. They were always willing to help with all passion. The foods on board were decent. I love it how they had Korean traditional foods and American foods for the choice! I had 2 free bags checked with 22kg for each which satisfied me. Also I brought 2 small carry on bags. The only thing is the English of some servers were not really good. Sometimes they didn't understand what customers said. But I think it is just fine

Nice wide seats, well run flight. Lots of food served, though very mixed quality. The unfortunate experiences described in the negatives of this review, do not repeat on the return flight.

In the fine print is the fact that the flight includes a stop in Shenzen. On the outbound flight this was a nightmare experience with Chinese immigration. Exhausted from a 14 hour flight, passengers had their passports taken away; were put through a bizarre 45 minute finger printing process using machines that did not work; and then left to wait for an hour or more with no information. The continuation flight was in another part of the airport - a very long walk; and it turned out not to be at the departing gate that was displayed on the monitors. We arrived at the indicated (wrong) gate with no guidance. Very nearly missed the continuation flight. Once in Xiamen, our arrival was late enough that the second floor of the airport was closed. There were no ATMs on the first floor; no way to get the Chinese cash needed to take a taxi to the airport. Fortunately a kind citizen agreed to exchange some cash, using mental calculations and sign language about the exchange rate.

2 free checked bags.

Old, uncomfortable seats. No in-seat power. Weak entertainment options on tiny screens. 3-4-3 configuration means no seat is a good seat. No legroom. I hated my experience on thus airline and will work to avoid on future trips to Asia. Paid $200 for two bulkhead (NOT exit row seats) and flight attendants hassled me about where I kept my carry-on tote bag. Avoid, avoid, avoid.

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.

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.
