I got to japan

I paid for Japan airlines because they are a clean airline and service is superior. Watch the fine print. My seat was dirty crumbs and leftovers left in the pouch and folding tray.

No big crowds trying to board. Everyone had room for their items in the over head. Love the one seat by itself. Very short flight but the one steward still served beverages and cookies.

This plane had more legroom than our international flight which was strange but at least it was better.

Flight out to BCN was one of the worst in my life! Never had an agent (BA Denver) talk to you and then mid conversation say they closed 3 minutes ago (7 minutes in to trying to find a flight alternative for their cancelled flight...and I wasn’t being upset!)

The in flight staff was very friendly

Our 2nd flight was changed by the airline, causing us to have a 6 hour layover in Philadelphia instead of a 2 hour layover. Then when we ask about changing to a different flight they told us that the original flight we were supposed to be on (that we booked over 8 months ago) was completely full so that’s why we were moved, and there were no other flights available to switch to. So we accepted that. But when we printed our boarding passes, we saw that our seats were now separate from each other, and they were both middle seats! I don’t understand how booking my tickets so far in advance still resulted in these issues. We were finally able to get an aisle and window seat (not near each other) but both flights had poor to little entertainment, which I wouldn’t have expected on such long flights with American Airlines. Really was letdown. :(

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.
