Marriott International has gone live with Concur's TripLink tool, allowing corporate travelers who book on Marriott websites to access corporate-negotiated content and for travel managers to capture those bookings. Other suppliers that have gone live include Airbnb, Avis and InterContinental Hotels Group. In March, Concur executive vice president of supplier management and travel management company services Mike Koetting told BTN all major car rental suppliers and three of the four leading U.S.hotel brands, including Marriott, had confirmed they would participate in TripLink. No airline has gone live with TripLink, but United Airlines plans to start beta testing in July.
