Hyatt used to have a super generous and game-able offer where anyone with even Hilton Gold (through a credit card signup) could get temporary Diamond status complete with confirmable suite upgrades.
They eliminated that last fall, and have been on again, off again at best with select status challenges that do not ‘advance’ top tier elite status.
With many members worried over Marriott’s acquisition of Starwood, Hyatt took to Twitter to look for disaffected elites from other chains and offer them status matches.
