Loyalty program Marriott Bonvoy is Marriott's loyalty program and was formed in the February 2019 merger of its three former rewards programs: Marriott Rewards, Ritz-Carlton Rewards, and Starwood Preferred Guest. Marriott Rewards was founded in 1983. Former loyalty programs Starwood Preferred Guest (also known as SPG) was founded in 1999 as the first in the industry to enforce a policy of no blackout dates, no capacity controls, and online redemption. In 2012, Starwood Preferred Guest began offering lifetime status and a dedicated Starwood ambassador for loyal members. Ritz-Carlton Rewards was founded in 2010. Members were able to receive air miles instead of reward points and able to earn ten points (or two miles) for every dollar spent on any Ritz-Carlton room rates. Despite the restriction of membership to only one of the two programs, members of Ritz-Carlton Rewards were able to earn points in other Marriott hotels, while Marriott Rewards members were able to earn points at a Ritz-Carlton.
