Mediocre 2.0

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"

Okay 4.3

Cons: This was a JetStar flight, not JAL as the title says. I've only had good experiences with JAL. Despite paying for two pieces of baggage, I had to pay an extra charge. One of my pieces was a pair of light skis (5kg, well below the allowed 20kg) that were apparently too long for normal baggage. It is just another way to extract an extra fee. Seat spacing on Jet Star is dismal. Thankfully it was a short 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,
please send us an and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
