GHA Discovery is the loyalty program for Omni hotels, Rydges, Alila (part of Two Roads Hospitality, which is being acquired by Hyatt), Kempinski, Anantara, Pan Pacific and more — 33 brands in total.
Discovery is an experiences program, not an earn and burn program. It’s all about status and recognition. Right now their top tier of elite status — Black — is available free on a trial basis. The offer may be restricted to cardholders in Middle East and Asia Pacific but I’ve already gotten 5000 American AAdvantage miles just by bouncing around and getting transferred a bit asking.
