Delta and Starbucks launched a loyalty collaboration in 2022. The partnership saw updates in 2024 and now faces another change effective August 5 2026. Under the new structure SkyMiles members earn one bonus mile for every dollar spent with Starbucks excluding tax gratuities gift cards and alcoholic beverages. Eligibility requires a qualifying Delta flight in the past 12 months or within the next 60 days. This returns to the earnings approach used at launch. The ability to earn Starbucks Rewards Stars remains unchanged. Enrolled US customers earn double stars on purchases made the same day as a scheduled Delta flight. Members must link their accounts to participate. Prior to the change earnings followed a tiered system based on account reloads. Loyalty program changes can have a big impact on customers who have built their routines around earning and redeeming rewards.
