In 2000, Starbucks and Marriott signed a long-term license agreement to open Starbucks locations in select hotels in the US and Canada. In June, the two brands launched a new partnership to let travelers link their accounts. Now, brands have added the ability to transfer Marriott Bonvoy points to Starbucks Rewards.

If you haven’t already, you must register for a Marriott Bonvoy and US Starbucks Rewards account to take advantage of this partnership. Then, link your accounts to Starbucks website. If you join as a new member of either program and link your account by October 18, you’ll earn 1,000 Marriott Points.

Here’s what you need to know about the Starbucks and Marriott partnership, including the new option to convert Marriott points to Starbucks Stars (and if it’s worth it).

Earn double stars during Marriott stays

You’ll earn double stars on the day you check out at Starbucks between midnight and 11:59 a.m. on the day you check out for an eligible Marriott Bonvoy stay. Eligible stays include those booked at eligible rates — incl With Marriott Points or Free Night Awards — if you link your account at least 48 hours before your stay and make your reservation at least 48 hours before check-in.

Double stars will appear in your linked Starbucks Rewards account within two business days of your qualifying Starbucks transaction. However, you can only earn up to 1,000 stars under the “Double Stars” offer during each June 18-to-June 17 program year.

Earn up to 100 points during Marriott Bonvoy Weeks

Marriott Bonvoy and Starbucks will occasionally announce a week designated as Marriott Bonvoy Week. During each Marriott Bonvoy week, members with linked accounts will earn 100 Marriott Points if they complete at least three qualifying Starbucks transactions. A qualifying transaction is “any purchase at a participating Starbucks store by a Linked Account Member of food, beverage(s) and/or merchandise, excluding purchases of alcoholic beverages, Starbucks Card eGifts, and physical Starbucks Gift Cards,” according to the Terms and Conditions. Conditions on Starbucks website.

To qualify, your purchase must be at least $2 and you must pay:

• Mobile order through the Starbucks mobile app or Starbucks website using a linked payment method or a preloaded Starbucks card registered to your Starbucks Rewards account.
• By scanning the barcode in your Starbucks mobile app before checking out

Not all Starbucks locations participate. Participating Starbucks stores are defined as locations in the US – including the 50 states; Washington, DC; and US territories — where you can earn stars. 100 points will appear in your Marriott Bonvoy account within two business days of the Marriott Bonvoy weekend if you complete at least three qualifying Starbucks transactions.

Transfer Marriott Points to Starbucks Rewards

You can convert Marriott Points to Starbucks Stars if you’ve linked your account. However, the transfer ratio is 1,000 Marriott Bonvoy points to 100 stars. Since 100 stars will only give you a bakery item or brewed coffee or tea, it is unlikely to provide good value. Finally, TPG’s September 2024 The valuation shows the value of 1,000 Marriott points at $8.50.

Therefore, we do not recommend transferring your Marriott points to Starbucks if you are looking to increase the value of your points.

Marriott points expire if your account is inactive for 24 months, while Starbucks Stars expire six months after the month you earned them. So, you may want to transfer Marriott points to Starbucks if you’re going to lose all your points due to inactivity, even though your rewards will typically expire very quickly in the Starbucks Rewards program.

If you want to transfer Marriott points to Starbucks, you can do so on the Marriott website.

The bottom line

This is far from the first partnership for Marriott Bonvoy or Starbucks Rewards. Delta Air Lines and Starbucks already have partnerships, as do Marriott and United Airlines.

While I don’t think transferring Marriott points to Starbucks Rewards offers good value, it’s worth linking your accounts so you can earn more on some Starbucks purchases. Even if you don’t get regular benefits, you can earn extra points or stars by doing so.
