Question: and if this has been answered before my apologies. I am a freshly minted Diamond Medallion on Delta. I was wondering on the upgrade list, when it comes down to diamonds competing for upgrades, what is the tie breaker? is it fare paid? Total YTD MQMs? Just curious. Or is a diamond a diamond? I know my upgrade percentage will go up a bit from Platinum, but just didn't know how the diamonds were ranked.

Thanks!
