Jim Hamilton L.B. Owens Airport (IATA: CUB, ICAO: KCUB) is a general aviation airport located in Columbia, South Carolina, United States. It serves primarily private, charter, and corporate aircraft rather than scheduled commercial airline service, functioning as a reliever airport for Columbia Metropolitan Airport (CAE). The airport is named in honor of Jim Hamilton and L.B. Owens, figures connected to the history of aviation and public service in the Richland County area. It is owned and operated by Richland County and supports a range of general aviation activities including flight training, corporate travel, and recreational flying. With a single runway and fixed-base operator (FBO) services on site, CUB plays an important role in the regional aviation network by reducing congestion at Columbia's primary commercial airport and providing dedicated facilities for non-airline aircraft operations.
