How to Accumulate Flight Mileage/How to request Post-flight Credit

How To Accumulate Flight Mileage

When making reservations, please provide your JMB membership number.
If you also participate in any of our partners' mileage programs, you must choose the program to which you want your mileage credited by giving only one program's membership number. Duplication of mileage credit between JMB and other mileage programs is not permitted.

Until your mileage has been credited to your account, please keep (a) your airline ticket copy or e-ticket receipt showing your itinerary and (b) your original boarding passes.

Flight mileage should be reflected in your account automatically within two to four weeks.

Mileage balance and activity can be checked in the following ways ;

Japan Region American Region Europe/Middle East/Africa Region Asia/Oceania Region

  • ・ In the JAL Mileage Bank, only one FFP membership number will be acceptable on one reservation record, either a JMB membership number or a JMB partner airlines’ Frequent Flyer program membership number.
    Transferring of mileage accrued from mileage program of other airlines (including JMB partner airlines) to the JMB account or vice versa is not permitted. Furthermore, it is not possible to combine mileage from the JMB account and other airlines’ Frequent Flyer program accounts when redeeming for awards.
  • ・ If your mileage has not been properly credited, you may request post-flight credit within 6 months of the flight.
