Utah-based SkyWest Airlines is seeking authority for a new nonstop between Washington Dulles International and Nassau International airports from June 2014.
The seasonal flight would operate under the United Express brand on an up to 70-seat Bombardier CRJ700, according to a regulatory filing on 4 February.
SkyWest says that United already has authority for the route, in its request.
Chicago-based United launched service between Washington Dulles and Nassau in December 2005. Service has since been discontinued.
No other airlines fly the route, Innovata schedules show.
American Airlines announced in January that its US Airways subsidiary would discontinue flights between Ronald Reagan Washington National airport and Nassau in 2014.
