How to compare fares effectively

Comparing prices across several channels at once gives you a clearer picture of the overall market rate, and helps you catch promotions at the right moment.

Airlines operating this route

This route has both full-service carriers flying direct and budget airlines that usually require a connection. If you'd rather save time and not haul heavy luggage through multiple airports, a direct flight pays off in the long run — but if budget is tight, a connecting flight can save real money, as long as you allow enough time between legs.

Preparing to fly to Japan

Before you travel, make sure your passport has at least 6 months of validity left, and register with Visit Japan Web in advance to speed up immigration in Tokyo. Also double-check your airline's baggage allowance — limits vary by carrier, so you won't get hit with excess baggage fees at check-in.

Tips for earning miles and seat upgrades

If you fly this route often, consider joining the frequent-flyer program of whichever airline you use most. Miles from tickets bought online add up, and you may eventually be able to use them for a seat upgrade or a free ticket on a future flight.
