Delta Air Lines said Tuesday that it will add Seattle-London flights next year, as it makes plans to begin coordinating its flights with Virgin Atlantic.
The flights to Heathrow will begin March 29 if Delta gets antitrust immunity for a planned joint venture with Virgin Atlantic. Normally, antitrust laws prevent coordination like that, but immunity is sometimes granted if regulators believe there will still be enough competition.
A few European airlines currently have non-stop flights on that route, including British Airways, which partners with American Airlines on flights to Europe.
Delta has been adding several long-haul flights from Seattle. It added Shanghai and Tokyo’s Haneda Airport in June; and Beijing and Osaka, Japan in 2010.
On Tuesday, Delta shares rose 8 cents to close at $20.45.
