United Airlines will end nonstop service between Chattanooga Metropolitan Airport and Washington-Dulles International Airport on Dec. 3, according to the travel website The Points Guy.
United spokesman Jonathan Guerin cited "low customer demand" for the cancellation of the service that started about a year ago.
"As we continuously review and analyze demand for business and leisure travel in all of the markets we serve, we have made the business decision to cancel service," he said in a statement.
But Guerin said United plans to expand its non-stop daily service between Chicago and Chattanooga to four times daily. The airline flies between Chattanooga and Chicago-O'Hare International Airport.
United began two flights daily between Chattanooga and Washington Dulles about a year ago. United had earlier suspended nonstops between Chattanooga and Newark Liberty International Airport before starting the Washington service.
American Airlines offers nonstop service between Chattanooga and Reagan National Airport in Washington, D.C.
