Now if it's just 150% I would see many not bother with running and just keep the JGC Green. An 8 to 10 extra legs that use to get you Premier or Diamond now nets you just Sapphire, probably not worth the time and $ spent. What they should have axed/changed is the 5,000 miles campaign to renew, not this. Make it so you need to fly at least Crystal level to maintain JGC Green or change the renewal amount to 10K.
