BETHESDA, MD — Marriott International has announced the termination of its licensing agreement with Sonder Holdings Inc. following what the company described as a default by Sonder.

As a result, Sonder is no longer affiliated with the Marriott Bonvoy loyalty program, and Sonder properties are not available for new bookings on Marriott’s channels.

According to Marriott, the company will be contacting guests who booked directly through Marriott channels – including marriott.com, the Marriott Bonvoy App and Marriott’s worldwide reservations centers – to address their reservation and booking needs. Those who booked through a third-party online travel agency should contact those organizations.

Guests with questions about current or future reservations at a Sonder property booked through Marriott channels can contact Marriott customer service here.
