Pros: Crew was excellent and the flight was great.

Cons: My Kayak account was opened in the US years ago. Google and Gmail are blocked in Mainland China. So if I book hotels or flights any updates or ticket information is sent to my Gmail account which I can never see I realize that too late and tried to notify you but you never answered back I realize that too late and tried to notify you but you never answered back. I feel I cannot use Kayak in China anymore.

Excellent 8.4

Pros: The boarding process was much easier and faster. No delayed flights.

Cons: I used the laboratory before takeoff as I was one of the first people on the plane and I forgot to go before I boarded. The hand soap container was empty and I had to tell one of the crew. Shouldn’t that have been taken care of before boarding passengers?

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.
