Head over to the JAL forum to look at the "Unofficial Guide" thread. It explains how it all works. JAL Mileage Bank is an interesting program for oneworld, and it will be attractive to some who are shopping for a oneworld frequent flyer program. One thing to understand is that JAL actually has two parallel recognition programs: JMB and JAL Global Club (JGC).
