Southwest Launches Flights from Sonoma County Airport

Southwest Airlines is expanding its California footprint with new service from Charles M. Schulz–Sonoma County Airport (STS) beginning in April. The carrier will offer nonstop flights to Denver, San Diego, Las Vegas and Burbank, bringing additional low-cost travel options to Northern California passengers.

According to the airline, daily service will operate between Sonoma County and both Las Vegas and San Diego, while flights to Burbank will run five days a week. Denver will initially be served with a Saturday-only flight, giving local travelers a direct link to one of Southwest’s largest hubs. These routes will connect Sonoma County residents to key leisure and business markets while offering convenient one-stop connections across Southwest’s national network.

The move marks a significant milestone for the regional airport, which has been steadily adding carriers and destinations as demand grows. For Southwest, the expansion supports its strategy of strengthening operations in secondary markets and offering more point-to-point service rather than funneling passengers through congested hubs.

Airport officials say the new flights will boost local tourism and business travel, while residents benefit from more competitive fares and schedule flexibility. With its signature two free checked bags and no-change-fee policies, Southwest expects the routes to attract both leisure and business travelers looking for affordable, reliable service.

By launching operations at Sonoma County Airport, Southwest underscores its commitment to expanding customer choice in underserved markets and positioning itself for further growth across California and the western United States.
