Window seat on a 14 hour flight has its pros and cons. Little more room vs having to wake people up to get up and walk or go to bathroom.

I was denied a boarding pass and was not allowed to transit through China, because of a visa that was needed I was not told about by Kayak.com. Therefore, being the last day I was allowed to stay in Thailand, I had to scramble to find an outbound flight the same day, including paying almost double the cost of the original flight. The Thai check-in agent told me to never transit through mainland China again, because the visa requirement information that is not provided.

2 free checked bags.

Old, uncomfortable seats. No in-seat power. Weak entertainment options on tiny screens. 3-4-3 configuration means no seat is a good seat. No legroom. I hated my experience on thus airline and will work to avoid on future trips to Asia. Paid $200 for two bulkhead (NOT exit row seats) and flight attendants hassled me about where I kept my carry-on tote bag. Avoid, avoid, avoid.

On both flights my party of 2 was split, despite an early check-in. We were lucky enough to swap seats because ANOTHER family was also split between us on the first flight. On the second, 3 parties were all split in the 3 rows in front of us, so we had to shuffle 4 different people before take off before the majority of the people were sat together. On 10 hour flights, generally I feel parties shouldn't be split unless they're checking in later than we did.

I accidentally left an external battery in my check in bag and they stopped me to open my bag and remove it as I was boarding. This is obviously my fault but I wish they had called me up earlier to not disrupt the other passagers and slow the boarding process.

Our flight was delayed for two hours. We have a connecting flight from Osaka to Los Angeles, which we were worried we couldn't make it. They told me the flight will wait for us because there were 20 plus people also need to get on that plane. When the time of boarding we heard they were calling us to the front and explained the flight we were suppose to be connecting already took off. They had to booked us to another airline. We were extremely disappointed! We asked if we could took another Japanese airline but they said our luggages were already transferred to that airline and the tickets were printed! Mosf importantly we have already waited in airport 5 hours and they needed us to wait for another 3 hours! Very bad experience with how they dealing with this situation!

Enjoyed the ANA service so much. The crew was so attentive and helpful. The floor was really wet under our seat and they got newspapers and blankets to keep our stuff dry and checked in on us several times. We felt very well taken care of. Enjoyed the documentaries on Japan and Okinawa!

We didn't know the meal schedule. We thought the half a sandwich at dinner time was dinner, but then a full meal came out a couple hours later. :) Nice surprise though!

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.
