Delta is celebrating 10 years of operations at London Heathrow - the U.K.’s busiest airport. The airline has grown from three flights a day in 2008 – one to Atlanta and two to New York-JFK – to nine daily flights to seven cities.

The 10-year anniversary comes in the same week as the launch of Delta’s A330-200 from Heathrow. The aircraft now operates on flights to New York-JFK and Atlanta, plus select services to Detroit, offering an enhanced onboard experience for customers in every cabin.

Delta’s access to Heathrow, the preferred London airport for business travelers, came about through the European Open Skies Agreement that went into force on March 30, 2008. Until Open Skies, Heathrow was restricted to two U.S. carriers: American and United, and two from the U.K.: British Airways and Virgin Atlantic. Other carriers including Delta, Northwest, and Continental were confined to the city’s secondary airport, Gatwick.

A decade (and a successful merger with Northwest) later, today Delta operates out of Terminal 3 alongside joint venture partner, Virgin Atlantic. Premium customers enjoy access to the Virgin Atlantic Clubhouse, Revivals lounge and exclusive Upper Class Wing check-in facility.
