Mile-Up Bonus

JMB Diamond members will receive bonus miles for every JAL Group, American Airlines, British Airways and Iberia flight traveled during the JMB Diamond eligibility period. To qualify, flights must be flown with fares eligible for JMB mileage accrual.

Accumulation rate based on FLY ON membership level

  • JAL Group flights: 130%
  • American Airlines flights: 130%
  • British Airways flights: 100%
  • Iberia flights: 100%
  • Mile-Up Bonus is not awarded in conjunction with bonus miles awarded to JALCARD holders or bonus miles awarded to JAL Global Club members. Members who are eligible for this mile-up bonus and other bonus mileage benefits will be credited with the most favorable bonus mileage rate.

Suspension of Mileage Expiration

As a general rule, JMB mileage is valid until the end of the 36th month after the flight (transaction) date. For JMB Diamond members, this mileage expiration will be suspended throughout the JMB Diamond membership eligibility period - meaning that your miles will not expire during this period.

  • Suspension of mileage expiration will take effect from miles that would normally expire at the end of the month following the month of Status qualification. FLY ON qualification date is the day on which the member meets the status qualification requirements based on FLY ON Points that are credited to the member's JMB account or the number of flights taken in one calendar year from January through December.
  • When your FLY ON status changes from JMB Diamond to another membership level, all mileage in your account at that time will be valid until the end of the 36th month after the date of the membership status change.
