Delta Air Lines has a multi-layered partnership network that provides its SkyMiles members with global reach. As a founding member of the SkyTeam Alliance, Delta is partnered with 18 other airlines, including Air France, KLM, Korean Air, Aeromexico, and China Eastern. These "Core Global Partners" offer the highest level of integration, allowing for seamless baggage transfers and lounge access. Beyond the alliance, Delta maintains significant Joint Venture partnerships with Virgin Atlantic (for transatlantic routes), LATAM (for South American travel), and WestJet (for trans-border Canadian flights). In 2026, Delta has also expanded its "Global Airline Partners" to include EL AL Israel Airlines and Scandinavian Airlines (SAS), following the latter's shift away from Star Alliance. These partnerships allow travelers to earn and redeem miles on over 1,000 destinations worldwide. For Medallion members, these links provide "SkyPriority" benefits—such as priority boarding and check-in—across the entire partner network, ensuring a consistent premium experience regardless of which tail fin is on the aircraft.
