MIAMI — Delta Air Lines and Virgin Atlantic have announced that both carriers will now operate exclusively from London Heathrow Airport Terminal 3, effective September 14.

The Atlanta-based carrier will transfer its Atlanta, Detroit, Minneapolis, Salt Lake City and Philadelphia flights from Terminal 4 to join its services to New York-JFK, Boston and Seattle that already operate from Terminal 3.

The move is seen as a means to ease travelers in obtaining assistance from both carriers, and it will allow Delta and Virgin Atlantic to interchangeably benefit in case of changes in the travel plans of customers, including last-minute flight changes.

“Our joint venture with Virgin Atlantic is all about making it easy for our customers to connect between our airlines and having our Heathrow service under one roof is crucial to delivering a synched-up, more convenient service,” said Nat Pieper, Delta’s senior vice president Europe, Middle East and Africa.

“This enhances the travel experience for customers flying from Heathrow, one of the world’s most important international gateways, and marks a major milestone in our joint venture.”

In total, Delta will operate 11 daily flights to eight U.S. cities nonstop from Terminal 3. The two airlines’ summer schedule includes up to 40 daily nonstop flights between North America and the U.K, of which 28 operate between London Heathrow and the United States.

Delta recently announced plans to decrease capacity on its US-UK routes this winter, largely attributed to a fall in the value of the pound and economic uncertainty.
