Miles & Status Points Earning

(when crediting to JAL Mileage Bank)

When crediting this Japan Airlines flight to JAL Mileage Bank, you earn both FLY ON Points (for elite status) and Miles (for award tickets). Here's how they work:

  • FLY ON Points: FLY ON Points are used for elite status qualification. Accumulate enough points within a calendar year to achieve higher status tiers, which unlock benefits like lounge access, priority boarding, bonus miles, and complimentary upgrades. Status points are calculated based on fare price or flight distance depending on the airline.
  • Miles: Miles are your reward currency for free flights. Redeem accumulated miles for award tickets on the airline and its partners. Miles earned depend on flight distance and your booking class. Higher booking classes earn more miles per flight.

The "FLY ON Points/$100" and "Miles/$100" columns show earning efficiency - higher numbers mean better value for your money. Compare different cabin classes to find the best balance between comfort and mileage earning.

As a oneworld member, Japan Airlines flights can be credited to partner programs. Compare earning potential:Executive Club, AAdvantage

Flight Itineraries & Booking Class Details

Browse 2 available flight options from Singapore to Seattle. Each itinerary shows the route, layover cities, flight duration, and detailed fare information.

📘What are booking classes?

Even within the same Economy cabin, tickets have hidden categories called "booking classes." Cheaper tickets get lower booking classes (Q, V, etc.) while expensive tickets get higher ones (Y, B, etc.). This dramatically affects how many miles you earn. On popular dates, cheaper booking classes sell out first, so closer to departure you may only find expensive fares—which do earn more miles. Click any fare to see the calculation details.

💡Smart booking tips

To maximize miles earned per dollar spent, look for fares with higher "Points/cost" or "Miles/cost" values. However, keep in mind that booking class also affects change/cancellation flexibility—cheaper fares often have stricter policies.
