Cons: We paid $37 to check in 1 Baggage and the flight from SFO to Beijing had delivered the baggage in baggage claim area. We had to take Chinese Visa to get to the baggage, even-though it is a transit. We missed the next connecting flight to Shenzhen as it ate up all our time. Now have to travel in the mercy of the airlines for next flight. PLEASE MAKE SURE YOU LIST THAT "VISA NEEDED IF CHECKING IN BAGGAGE"

Mediocre 2.0

Pros: I was stranded by not being aloud to board the plane there was a visa problem at my destination the air China staff required me to have a visa to enter the country of India. There is a tourist visa for under 180 days stay. That’s what I get when I enter on a land route just a 60 day visa upon arrival so the agents would not let me board. Air China sent me a note that I could cancel the flight and should be able to get a refund. I have called 6 times already and have yet to speak with anyone I stayed in the station all night and at 9 am today they will give be a number that will work

Cons: I would like to get a full refund

Cons: I know that you have nothing to do with the reservations, but vayama flew me to bali with no return ticket. I even emailed them to confirm my reservation when I was in bali, but when I went to fly home I had no reservation and had to purchase a flight home. This is outrageous and I'm pretty sure illeagal. Now I know you had nothing to do with the reservation my original search started with you for that reason I will not be using kayak, vayama, nor eva air ever again and will suggest everyone I can to do the same. This is outrageous that i had to buy a return ticket home until i get a refund i will not stop.

Pros: The seat recline in a way that doesn't really take space away from the person behind you. Your seat bottom juts forward while you recline back. I slept the whole way, save for the two meals, from London to Bangkok. A thirteen hour flight felt like two.

Cons: Food needs a rethink.

Pros: Plane left late from Manila and was asked to run to catch the connecting flight to LAX. Monitor did not work. Flight attendant/s were rude whenever their asking to stow away foot rest. Never say please. When I got to LAX, I needed to wait for the very last luggage for me to find out that my luggage was left in Guangzhou. No apologies whatsoever and was given a direction to file a report. Very sad experience.

Cons: Focus on customer service. More training with staff since they are dealing with different nationalities.

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.

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.
