Should I book a round-trip or one-way ticket?

Round-trip is almost always cheaper for Japan flights, sometimes by $300-500. Only book one-way if you're continuing to other countries or staying more than a year.

Is it worth paying extra for premium economy?

On 11+ hour flights to Japan, the extra legroom and better meals justify the $300-500 upgrade for most people. Business class is harder to justify unless you can sleep on planes.

Can I change or cancel my Japan flight?

Depends on fare type. Basic economy tickets are usually non-changeable. Main cabin allows changes for $200-400 plus fare difference. Buy flexible tickets or travel insurance if your plans might change.

Which airport is better: Narita or Haneda?

Haneda is more convenient (30 minutes to Tokyo vs 60 for Narita) but often $100-200 more expensive. Choose based on your budget and whether you're staying in Tokyo proper.

How to Book Flights to Japan

Book Japan flights 2-3 months ahead for best prices, typically $800-1,400 from the US. Use Tokyo Narita (NRT) or Haneda (HND) as your main entry points. Tuesday and Wednesday departures are usually cheapest.

Choose your arrival airport. Tokyo has two main airports: Narita (NRT) is 60km from city center but often cheaper, Haneda (HND) is 30km away but pricier. Osaka Kansai (KIX) works well for Kyoto/Osaka region. Avoid smaller airports unless you're staying nearby.
Time your booking window. Book 8-12 weeks ahead for economy. Prices spike 6 weeks before departure. Tuesday/Wednesday departures cost $100-200 less than weekend flights. Avoid Golden Week (late April-early May), Obon (mid-August), and New Year periods.
Compare these booking sites. Check Google Flights first for overview. Book directly with airlines for better customer service. ITA Matrix shows complex routing options. Momondo catches deals others miss. Skip Expedia-type sites for international flights.
Pick your route strategy. West Coast: Direct flights from LAX, SFO, SEA run $800-1,200. East Coast: One-stop through Vancouver, Seattle, or San Francisco adds 3-5 hours but saves $200-400. Consider open-jaw tickets if visiting multiple Japanese cities.
Know the airline differences. JAL and ANA offer excellent service, included meals, bigger seats. United/American are serviceable but basic. Avoid budget carriers like Jetstar for transpacific - the savings aren't worth it on 11+ hour flights.
Secure your booking. Use credit cards with no foreign transaction fees. Screenshot your confirmation. Check passport expiration - needs 6+ months validity. Consider travel insurance if booking expensive tickets far in advance.
