Yes, Delta Air Lines is a founding member of the SkyTeam Alliance, having helped launch the global partnership in June 2000 alongside Air France, Aeromexico, and Korean Air. In 2026, Delta remains the dominant North American pillar of the alliance, providing seamless connectivity for travelers across its massive hub network in Atlanta, Detroit, and Minneapolis. Being part of SkyTeam means that Delta SkyMiles members can earn and redeem miles on over 18 partner airlines, including Virgin Atlantic, KLM, and SAS (which officially joined the alliance in late 2024). For travelers with "Medallion" status, SkyTeam provides SkyPriority benefits worldwide, such as priority check-in, boarding, and access to hundreds of partner lounges like the Air France Lounge in Paris or the Korean Air Lounge in Seoul. This alliance is the key to Delta's global reach, allowing a passenger to book a single ticket from a small regional airport in the U.S. to a remote destination in Asia or Africa with a unified baggage and check-in experience.
