Yes, Delta Air Lines and Virgin Atlantic are deeply integrated partners through a transatlantic joint venture that began in 2013. Delta currently owns a 49% stake in Virgin Atlantic, and the two airlines operate as a single entity for routes between the UK and North America. This partnership allows for seamless codesharing, meaning you can book a Delta-operated flight on the Virgin website and vice versa. For travelers, this means reciprocal loyalty benefits: Delta SkyMiles members can earn and redeem miles on Virgin Atlantic, and Virgin’s Flying Club members can do the same on Delta. The partnership also provides mutual lounge access for elite members and coordinated flight schedules to provide more connection options at hubs like London Heathrow and New York JFK. In 2026, this remains one of the most powerful and stable alliances in the aviation industry.
