JAL Mileage Bank

JAL Mileage Bank is Japan Airlines’ programme. JMB Miles are the redeemable balance; FLY ON Points and flight counts serve a different status task. This profile separates the balance you can spend from the measures used for elite status.

How flights earn

A flight earns the applicable percentage of its official IATA Ticketed Point Mileage. Domestic, international and special-fare tables differ.

Miles or points to spend

JMB Miles are the redeemable balance.

Elite status qualification

FLY ON Points and eligible flight counts support elite status. The JGC lifetime-style programme is a separate path.

Expiry

Miles normally expire at the end of the month 36 months after they were earned. Diamond members and some JGC tiers have exceptions.
