The seat was nice

Service was extremely slow, it took almost two hours just to get offered a drink. There wasn't any offering after boarding and I had to ask just to get water. The food was quite bad, normally I would choose the Japanese meal, however, both the Japanese and International options were poor. The staff seemed unorganized and did not follow a set protocol.

Hot food was good. Crew were friendly and helpful. They got me a window flight even though it wasnt on my ticket. Leg room was pretty good. Bathroom had a lot of amenities.

The seats didn't recline at all. I slept horribly even though I'm pretty good at sleeping on planes.

I was randomly upgraded for the first 10 hours of my trip to Premium economy and it was amazing. Two big hot meals served throughout the flight and plenty of drink service. lots of leg room and could recline comfortably. Flight attendants were wonderful and very helpful. Lots of new movies to watch and games to keep you entertained.

Flew economy for the 2nd part of my trip and the seat was very hard and was impossible to get comfy. Same meal service as premium economy and was once again delicious. Much colder on this flight and the thin blankets do very little to help.

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,
