got us there on time, Customer care was helpful but wish there was an easier way to fix a problem at the airport instead of calling in to a help desk.

they didn't have the arrival cards for me, which they usually do. Traveling with 4 kids by myself and having to do customs by myself without the time on the plane to work through the cards made it difficult. Also there was a typing error on one of my children's tickets that was an airline error but still requires a phone call from me and a fine to fix even with the plane leaving in one hour and having three other children at the gate waiting. There has to be an easier way to fix a mistake that happens in the airport.

We spent 2 hours at the check in because China eastern changed our connecting time and we were going to miss our flight. The food was terrible, they lost my husbands luggage. We are on our honeymoon and he has no clothes. And they put us up in a very dirty hotel.

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.
