Starwood Preferred Guest and Delta SkyMiles work together through Crossover Rewards to offer more rewards in both programs. These Crossover Rewards benefits are in addition to the current Starpoints you earn when you stay at a Starwood resort, or the current miles you earn flying with Delta. Here is how the program works…
Fly Delta And Earn SPG Rewards And Get SPG Benefits–SPG Platinum and Gold members earn 1 Starpoint for every dollar spent on eligible Delta flights. To earn the SPG points, the flight must be one in which you are eligible to earn SkyMiles, in other words, a paid flight. Besides earning SPG points, SPG Platinum members enjoy elite benefits when traveling with Delta, such as Priority Check-in, Priority Boarding, Unlimited Complimentary Upgrades, and first checked bag free.
Stay At A Starwood Resort And Earn Delta Miles And Get SkyMiles Benefits–SkyMiles Diamond, Platinum, Gold and Silver Medallion members earn 1 mile for every dollar spent on eligible room rates at Starwood hotels and resorts. To earn the SkyMiles, the stay must be one in which you are eligible to earn Starpoints, in other words, a paid stay. Besides earning SkyMiles, Diamond and Platinum Medallion members receive additional SPG benefits at Starwood hotels and resorts — 4 p.m. late checkout, access to the SPG elite check-in line, complimentary in-room Internet access and an upgrade to an enhanced room at check-in, when available.
