Upgrade to  Marriott Bonvoy Gold Elite Status. 

As a Platinum member you are eligible to enroll in complimentary Marriott Bonvoy™ Gold Elite Status. Once you request enrollment within the Marriott Bonvoy™ Program (“Marriott Bonvoy™”) at the Gold Elite Status level, American Express will share your enrollment information with The Marriott Bonvoy™ Program (“Marriott Bonvoy™”). Marriott Bonvoy may use this information in accordance with its privacy statement available at www.marriott.com/privacy. You will maintain Gold Elite Status without meeting otherwise required Marriott Bonvoy criteria as long as you remain an eligible American Express Card Member or until American Express notifies you that the benefit is terminated. Marriott Bonvoy member benefits are subject to change, availability and certain eligibility requirements. Reservations booked through third parties and online booking sources are not eligible. For complete Marriott Bonvoy Program terms visit Marriott Bonvoy Loyalty Program Terms & Conditions. Marriott Bonvoy program amenities may be combined with the Fine Hotels & Resorts program. Upgrades are based upon availability and will vary by property.
