My spouse just got AmEx Platinum card, and I am an Authorized User (for $175 additional fee).

What benefit do I get (independently from the primary user)? I know not the $200 Uber reimbursement.

But can I get my own Priority Pass, Hilton Gold, SPG Gold, rental car elevated memberships, airline $200 fee reimbursement, etc.?

For the primary user, these offers were available under Benefit section online. I still see the same items on my account, but it no longer offers a link to enroll (at least for the above offers I am interested in.)
