What is Flight Mileage?

In order to accrue miles, your JMB membership number must be provided in 9 digits*1 when making the reservation or at check-in. Additionally, all tickets must be issued in the JMB member's name. Flight mileage is based on the sector mileage specified for the sector(s) traveled and on the accumulation rate for the fare of the purchased ticket.
