Boarding went smoothly. Take off and landing were great. Plane seat was comfortable.

Crew seamed "burnt out" on their job. No one was rude or anything. They just didn't seem happy at all. Insincere.

The crew was nice and the area was clean.

I didn't like the fact that before boarding they offered to check peoples bags for free because so many people were trying to take ridiculous sized bags onto the plane. I always pay to check my bag . That process took for ever but we did still arrive on time.

economy plua has a reasonable amount of room, good food for breakfast, nice movies in flight.

they canceled our flight to hanaeda and instead had us take an hour later flight to narita which is a 1 1/2 hour $30 bus ride away which they don’t pay for. this caused us to miss our connecting flight to Asahikawa, the last flight of the day. The connection time allowed was not nearly enough even if the plane had not been an hour late and there are no flights to asahikawa from narita. yo have to transfer to hanaeda. remind me not to fly United to Tokyo again as I’m pretty sure the flight was canceled because it was not full enough. Even the narita flight with all the hanaeda passengers rebooked on it was not full. So i suspect this may be a relatively common occurance on the hanaeda flight.

We stood in line forever to then be told the clerk couldn't ch we ck us in. When we tried the kiosk it didn’t work. Long story short we missed our flight due to their poor organization of the line and crowd.

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.
