The inflight entertainment options could be more current. We found the options limited... it was a good thing that the flight was short.

The style of the pillows and blankets were nice. The pillows were really comfortable and a good size. The taste of the food was okay. I honestly expected a horrible experience, it was not fantastic but it was better than what I anticipated.

The sealed blanket had white hair as if from an older person. Although I liked the pillow, on my return flight I used it to sleep, I used it for my back the entire time going, when I got home I noticed I was developing a sty on my eyelid. My companions noticed that the sometimes when he received his food it was still cold in some parts. On my return flight there were a few times my row was skipped for drinks. On my return flight the stewardess seemed hesitant when I asked for an additional drink. I ordered tea and asked for water. The gate agent in Beijing was extremely rude and unhelpful, she ignored us and even tossed our ticket back at us when we tried to ask about our seats for the flight.

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,
