Buchanan Field

Buchanan Field Airport in Concord, California, originally opened in the early 1940s, operates with a single small terminal and numerous hangars and is one of the busiest general aviation reliever fields in the East Bay. The airport’s compact footprint makes it a popular base for flight schools, corporate operators, air ambulance and on-demand charter services rather than scheduled airlines. It’s easily reached from Highway 4 and I‑680, with short taxi or bus links to downtown Concord and nearby BART for regional connections. Costs are generally modest for private flights and parking, but there’s limited commercial service — travelers often compare fares at SFO and OAK for cheaper scheduled options.
