Marriott Bonvoy: How Marriott Rewards Became Bonvoy in 2019

Marriott Bonvoy is Marriott International’s single loyalty program, launched in 2019 after Marriott merged three separate programs into one: Marriott Rewards, The Ritz-Carlton Rewards, and Starwood Preferred Guest. The merger followed Marriott’s $13.3 billion acquisition of Starwood Hotels & Resorts, which closed on September 23, 2016. Today Bonvoy counts more than 300 million members across Marriott’s global portfolio.

That history explains a lot of the confusion members still run into. If you earned points as Marriott Rewards or SPG before 2019, you’re not holding some separate, orphaned currency. You’re holding Bonvoy points under an old name.

What Was Marriott Rewards?

Marriott Rewards was Marriott International’s original loyalty program, running separately from Starwood’s own program for decades before the two companies merged. It covered Marriott’s core brands directly, Marriott Hotels, Courtyard, Residence Inn, and others, while The Ritz-Carlton Rewards operated as a related but distinct program for Ritz-Carlton stays.

Starwood ran its own program in parallel, called Starwood Preferred Guest, or SPG, covering brands like Sheraton, Westin, and W Hotels. SPG had a loyal following of its own, and many frequent travelers held balances in both programs simultaneously without any way to combine them.

That split created real friction for anyone who traveled across both hotel families. A member building status with Marriott Rewards got no credit toward SPG elite status, and vice versa, even after the two companies technically became one in 2016. Picking a single program to concentrate stays in meant leaving value on the table with the other, which is exactly the problem Bonvoy was eventually built to solve.

How the Starwood Acquisition Created Marriott Bonvoy

Marriott closed its acquisition of Starwood Hotels & Resorts Worldwide on September 23, 2016, in a deal worth $13.3 billion. The acquisition immediately made Marriott the largest hotel company in the world by room count, combining Marriott’s existing portfolio with Starwood’s brands, including Sheraton, Westin, W Hotels, and the St. Regis.

Buying the company was the easy part. Combining three separate, long-running loyalty programs into one took three more years. Marriott Rewards and The Ritz-Carlton Rewards linked accounts first, letting members move points between the two programs. SPG stayed separate a while longer, since its members and its program structure differed enough from Marriott’s own that a straight merge risked frustrating a loyal base.

What Changed When Marriott Rewards Became Bonvoy in 2019

Marriott launched Bonvoy in 2019 as the single replacement for all three legacy programs at once. Every Marriott Rewards, Ritz-Carlton Rewards, and SPG member became a Bonvoy member automatically, and existing point balances converted into the new program rather than resetting to zero. Nobody lost points in the transition, though the exact conversion math varied depending on which legacy program a member came from.

The new name itself was a deliberate break from the past. Marriott wanted one brand covering all three loyalty histories, not a name borrowed from any single legacy program, which is part of why “Bonvoy” replaced “Marriott Rewards” entirely instead of simply absorbing SPG into the existing Marriott name.

Marriott Bonvoy Today

Marriott Bonvoy now counts more than 300 million members worldwide, a figure that’s grown steadily since the 2019 launch. The program spans more than 9,700 properties across more than 30 brands, from budget-friendly Four Points to luxury names like St. Regis and The Ritz-Carlton, all under one loyalty account.

Elite status runs through six tiers: Member, Silver, Gold, Platinum, Titanium, and Ambassador Elite. Reaching Silver takes 10 qualifying nights in a calendar year, while Ambassador Elite sits at the top, requiring 100 nights plus a substantial annual spend threshold. Each tier up the ladder adds real perks, from late checkout at Silver to a dedicated Ambassador contact at the top.

The scale difference from before the merger is significant. Marriott operated 4,494 properties on its own just before the Starwood deal closed in 2016. More than doubling that footprint since then gave Bonvoy members a genuinely wider net than either legacy program offered alone, particularly for travelers who split their trips between business-focused brands like Courtyard and luxury properties like St. Regis or The Ritz-Carlton.

What You Can Actually Do With Marriott Bonvoy Points

Points earned through stays, co-branded credit card spend, or dining and retail partners redeem for free nights, room upgrades, and experiences through Marriott’s Moments platform. Bonvoy also transfers to more than 40 airline partners, typically at a 3:1 ratio, which opens redemptions well beyond hotel stays alone.

Walking through the actual math behind buying, selling, and earning points takes more room than a history explainer has. Our full guide to buying, selling, and earning Marriott Bonvoy points covers current promotions, transfer ratios, and the actual numbers behind each option. If you just want to know what your balance is worth per point, our 2026 Marriott Bonvoy valuation guide breaks that down directly.

What To Do With Old Marriott Rewards or SPG Points

Legacy Marriott Rewards and SPG points converted into Bonvoy points automatically back in 2019, so there’s no separate action needed to access them today. They sit in your Bonvoy account under your current balance, not in some dormant account tied to a program that no longer exists.

A balance that’s grown past what you’ll realistically redeem, whether it started as Marriott Rewards, SPG, or straight Bonvoy earning, is worth a second look if travel isn’t in your near-term plans. The Miles Market buys Marriott Bonvoy points directly, including legacy SPG balances, with a quote based on real market demand and payment sent before your points are touched.
