your QF comment about "confirmed upgrade 7day out" is misleading. its not upgrade for free, rather unlike other lowly Platinum whos upgrade request (using own point) come closer to say 76 hours prior to departure, P1 request processed even sooner.

CX Diamond plus is strictly revenue based, the card would state DM+ and you are recognized as such. CX also have a "invitation" membership which is non revenue based rather ggiven to influential figures and heads of government or CEOs of multinational conglomerate of high profile. invitation are classified as regular diamond tier (emerald) and not the super tiers. .anacdotally i suspect DM+ equiring 3x regular emerald alongside AY and QF seems about right, but it must come from hard money and critetia is withheld. i would assume most need to be CX based so some poor bloke doing LONE6 every week wont qualify for it
