I have another question,
on the JAL website it says to gain JMB Sapphire you need to accrue "50,000 FLY ON Points (including 25,000 FLY ON Points for JAL Group flights)", however the conditions on the JGC qualification don't have the JAL flights requirement, is this an oversight or could I fly 50000 miles and get JGC membership without getting JMB membership?
