Brown Field Municipal Airport (SDM/KSDM) is a city-owned general aviation airport in San Diego's Otay Mesa community, about 15 miles southeast of downtown and just north of the U.S.-Mexico border. Established in 1918 as East Field and later renamed for Ensign Charles R. Brown, it has a long military and civilian history. Today it supports private, charter, flight-training, law-enforcement, and customs-enabled international general aviation operations, with no scheduled airline service.
💡 Local Tip
Because it sits inland from the coastal marine layer, Brown Field often remains VFR when San Diego's coastal airports are fogged in—making it a useful alternate or departure point for early-morning flights.
🚖 Getting There
The airport is easiest to reach by car via I-805 and SR-905, with rideshare and taxi service available but best arranged in advance. There is no direct rail link; MTS buses serve parts of Otay Mesa, so check current routes if using public transit. Allow extra time for traffic near the Otay Mesa border crossing, especially during peak commute hours.
