Back to square one it seems
I had until yesterday to bank 500 points in past six months to keep gold status. I was at $460 spending as of last night, needing $40 more for both a $5 credit and renewing gold. Unfortunately, it seems that while I still can get the $5 with $40 more in spending, which is fine via Amex credits, the gold status is now off the table. I show that I need the full $500 in the next 6 months for that. Moreover, with blue status I now have a chance to earn a measly 5% off rides after I complete 6. Yesterday, I was traveling at 50% off.
