STS Airport (Charles M. Schulz Sonoma County Airport) – Cargo, Address, Transit

About This Airport

Alaska Airlines, American Airlines and, since 7 April 2026, Southwest Airlines share the ramp at Charles M. Schulz Sonoma County Airport (IATA: STS, ICAO: KSTS), which handled a record 780,637 passengers in 2025 after 772,758 the year before. Named for the Peanuts cartoonist who lived in the area for decades, the field near Santa Rosa is the North Bay's only scheduled-service airport, and Southwest's Boeing 737s added nonstops to San Diego, Las Vegas, Burbank and Denver. No dedicated freight terminal or regular freighter operation is confirmed at STS, so air cargo is limited at best to belly space on passenger flights. Sonoma and Napa wine leaves by truck, the SMART commuter railway stops at the airport but carries passengers only, and the field doubles as an air tanker base during fire season. Imports and exports are therefore routed through Oakland (OAK) or San Francisco (SFO), each roughly 100 road kilometres south on US 101 and both offering customs clearance, with Sacramento (SMF) as a further option. Record traffic pushed the operator into a 15-year expansion plan in 2026 that includes a larger terminal, for which neither funding nor a schedule has been set.
