Excellent 9.3

Pros: Excellent service and probably the most efficient boarding process I’ve ever been a part of. Food service went by without a hitch, and the stewardesses knew English very well so we felt comfortable and welcomed. I also really liked being able to get terminal/travel information from the infotainment system. Being that I’ve never been to ICN or NRT before, having access to terminal maps and basic instructions on how to find connecting flights and baggage claim areas was probably one of the most helpful features of the flight!

Cons: I am 5’11” and found my seat somewhat uncomfortable. It didn’t detract from being able to sleep at all, but it did seem like the seats on this airline might be at its most comfortable with shorter 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,
