Hyatt Discoverist benefit, whatever that is worth, is going away in 2020 according to an email sent today:
We want to let you know about an upcoming change to your United Presidential Plus Card...
As a primary Cardmember, you will be able to enjoy Discoverist status in the World of Hyatt® loyalty program¹ until February 29, 2020, but you must register for this Hyatt benefit by December 31, 2018. You will no longer be able to register for this Hyatt benefit after December 31, 2018.
If you've already registered for Discoverist status in the World of Hyatt program, you don't need to register again. Your status will remain active through February 29, 2020, as long as you remain a Cardmember.
Thank you for being a Presidential Plus Cardmember.
