I'm just happy that current JGC members (including JGC family members) get grandfathered into the new JGC program and get to keep OW Sapphire status. The rest of the system is just too complicated. I don't have the time or the energy to understand it. I do wonder if I will get new luggage tags, since I just passed 500,000 lifetime miles last month.
Will be interesting to see if ANA tweaks their SFC entry criteria...
