whoops! Apologies; didn’t mean to be unhelpful in *that* way. CK = ConciergeKey , which is an elite level above Executive Platinum. Criteria for CK are not published and are not as straightforward as for the other levels, but effectively the criteria is “super profitable”. Note that many folks don’t have a great understanding of how profitable vs “super profitable” they are, so there’s a lot of misunderstanding and misinformation out there about CK.
