American Airlines will launch flights from Atlanta to its hub at Washington Reagan airport starting Jan. 5, offering five flights a day.
Fort Worth, Texas-based American plans to fly the route with 76-seat Embraer 175 planes. The carrier hasn't flown the route since 2008.
"We've seen the demand for it and we need to be in the market with the pattern of service that meets the demand for business travelers," according to American Airlines spokeswoman Jenna Arnold.
The move will add competition to the market, which is already served by Delta Air Lines and Southwest Airlines.
Delta, the dominant carrier in Atlanta, operates 15 daily flights between Atlanta and Washington Reagan, and also flies from Atlanta to Washington Dulles and Baltimore Washington International.
Southwest operates six daily flights between Atlanta and Washington Reagan, also flies from Atlanta to Baltimore and will launch service between Atlanta and Washington Dulles in March 2016.
American already operates flights from Atlanta to its hubs in Dallas, Los Angeles, New York LaGuardia, Miami, Chicago, Charlotte, Philadelphia and Phoenix.
