Charles M. Schulz Sonoma County Airport (STS) serves Santa Rosa, California, in the United States, located about 7 miles from the city center. The airport sits at an elevation of 125 feet above sea level.

As a regional airport, STS provides a smaller-scale alternative to the larger hubs of the surrounding area, primarily supporting domestic air travel within the United States. Its modest elevation and coastal Northern California setting place it in a region where marine layer conditions and seasonal weather patterns can influence flight operations. Travelers using this airport typically connect to other domestic points rather than international destinations, reflecting its role as a regional gateway for the North Bay area of California.

Given its proximity to Santa Rosa, the airport offers a convenient option for travelers seeking to avoid the congestion of larger metropolitan airports while still accessing domestic air travel networks. The relatively low elevation and location near the Pacific coast are relevant factors for pilots and travelers considering local atmospheric conditions. Overall, STS functions as a compact, community-oriented airport supporting regional connectivity for Sonoma County and the broader North Bay region.
