That's a non-sequitur.

The grant of elite status is ultimately an economic transaction. The guest directs a certain amount of business in exchange for specified benefits. "Fairness" doesn't have anything to do with it.

Hyatt of course gets to choose the amount of business it will require for a specified level of benefits. And we get to choose whether to direct our business to Hyatt.

What many here are saying is that Hyatt's adoption of a 60 night / $20,000 threshold for Diamond, along with really crappy Explorist benefits, makes the value proposition irrational and/or impossible, particular given Hyatt's limited footprint. Hyatt will thus lose some amount of business from guests who currently direct at least 25 stays but less than 60 nights/ $20,000 per year. It is not unreasonable to assume that is a significant chunk of business.

And it's not clear that Hyatt has accurately gauged its customer base's reaction to the changes it has made. They seem to believe that many current Diamonds will stick around for Explorist. My prediction is, they won't.

But again "fairness" has nothing to do with any this.
