News / Fly for peanuts! Southwest to serve Charles M. Schulz Sonoma County Airport in April 2026
The new route will provide travelers with more direct access to the Sonoma region

In a September surprise, Southwest Airlines Co. has announced that it will begin operating services to Santa Rosa, California’s Charles M. Schulz Sonoma County Airport (STS) on 7 April 2026. Initial flights will be available to purchase on Southwest.com®.
Seeing Red: Woods and Wines
Inaugural service for Southwest Airlines® at Santa Rosa (Sonoma County), California, will connect nonstop to San Diego, Las Vegas, Denver, and Burbank, California. The San Diego and Las Vegas routes are set to operate daily, including two San Diego roundtrips on peak days. Burbank will initially operate five days per week and Denver will operate on Saturdays only.
The airline previously announced new service to St. Thomas, United States Virgin Islands; Knoxville, Tennessee; and St. Maarten, all scheduled to begin throughout the first half of 2026. The airline intends to moor another new destination to its route map soon.
California Here We Come
Southwest® offers, without regional carriers, more intra-California service than any other airline.1 It also leads in available seats, daily departures, and proudly carries the most passengers in the Golden State.1
STS, the airport adorned with the beloved cartoon characters, will be the 14th in Southwest’s California catalog, connecting Wine Country to the soon-to-open new Terminal 1 in San Diego, as well as the reimagined Hollywood Burbank Airport on Southwest marketed- and operated-flights.
