Delta Air Lines Inc., the world's biggest airline, has finalized a seven-year lease extension at Hartsfield-Jackson Atlanta International Airport.
Atlanta-based Delta and the city first announced the deal, which runs through 2017, in October. The city, which runs the world's busiest airport, said Monday the agreement confirms the airport will be a major player in the region's economic recovery.
Earlier this year, Delta threatened to move some flights to other airports if it couldn't maintain competitive costs at the airport. AirTran Airways had said it would consider doing the same if suitable new lease agreements couldn't be reached at Hartsfield-Jackson.
The two carriers represent roughly 93 percent of the traffic at the airport.
