Marriott added more than 40 million loyalty members in 2025, a figure the company reported as part of its full-year results for the Marriott Bonvoy program.

The number marks one of the largest single-year membership gains disclosed by a major hotel loyalty program, and it arrives as travel brands compete to convert frequent guests into direct, app-based bookers rather than third-party channel customers.

What does the 40 million figure mean for marketers?

Loyalty membership has become the primary battleground for hotel chains fighting commission costs on online travel agencies. A larger member base gives a brand first-party data, direct-booking volume, and owned channels for personalization and upsell.

For marketing leaders, the takeaway is straightforward: Marriott's scale in loyalty sign-ups shows where travel-sector budget and product attention are moving. Member acquisition at this volume requires coordinated investment across:

• App and digital account onboarding
• Co-branded credit card partnerships
• Property-level enrollment at check-in
• Promotional pricing available only to members

Why does the number matter now?

Hospitality brands have spent the past several years pushing enrollment at every touchpoint, from booking flows to front desks. A gain of more than 40 million members in a single year indicates those prompts are converting at scale for Marriott.

The disclosure also gives CMOs in adjacent categories a benchmark. Hotel loyalty growth competes directly with airline programs, credit card rewards ecosystems, and general retail membership schemes for the same share of consumer wallet.

What should marketing leaders watch next?

The headline number is enrollment, not engagement. The open questions for Marriott Bonvoy and its rivals in the coming quarters are:

• What share of new members book directly rather than through third parties?
• How does member data translate into repeat stays and higher lifetime value?
• Will co-brand card partners accelerate acquisition further?

Marriott reported the figure through coverage by CX Dive. The company has not yet broken down the regional or channel-level drivers of the 2025 gain in the material summarized here.

For now, the number stands as the story: more than 40 million people joined Marriott's loyalty program in 2025, and the competition for owned-customer relationships in travel keeps intensifying.
