Overview & The Peanuts Connection
Charles M. Schulz-Sonoma County Airport (KSTS/STS) sits about 7 miles northwest of downtown Santa Rosa and is owned and operated by Sonoma County. It is named for Charles M. Schulz, the Peanuts cartoonist who lived in Santa Rosa for more than three decades; a Snoopy 'flying ace' motif greets arriving traffic. The airport blends scheduled commercial service with a deep general-aviation and business-aviation base, making it the natural private-jet entry point for Sonoma and Napa wine country.
Runway Capability
KSTS has two grooved-asphalt runways: primary 14/32 at 6,000 feet and crosswind 02/20 at 5,202 feet. The 6,000-foot length supports light through most super-midsize jets without difficulty, and the modest 128-foot field elevation keeps performance penalties low. Heavy-jet crews should run runway-specific takeoff numbers for full-fuel, warm-day departures, but the airport handles the bulk of charter aircraft visiting wine country with margin to spare.
Charter Considerations
Two full-service FBOs — KaiserAir Santa Rosa Jet Center and Sonoma Jet Center — provide Jet-A, hangar and ramp handling, and concierge ground transportation to wine-country resorts and tasting rooms. STS is a popular harvest- and event-season destination (crush, Sonoma Raceway events, weddings), so ramp space and hangar availability tighten in fall; The Jet Finder recommends booking handling and parking early for peak-period trips.
Safety & Planning
KSTS has an FAA control tower operating roughly 0700-2000 local; outside those hours the field reverts to a non-towered (CTAF) procedure. Instrument approaches include ILS and RNAV (GPS) serving runways 14, 32, and 02. Coastal stratus and morning fog are the most common operational factors, occasionally driving IFR or MVFR conditions that lift by mid-morning. Part 135 charter flights file IFR, so professional crews plan around marine-layer timing rather than being limited by it.
Customs & International Trips
KSTS does not have on-field U.S. Customs and Border Protection service, so it cannot serve as a first point of entry for international arrivals. Inbound international charters typically clear customs at San Francisco (SFO) or Oakland (OAK) before repositioning the short hop to Santa Rosa. The Jet Finder coordinates the clearance airport and tech-stop logistics so passengers reach wine country with minimal added ground time.
Regional Context
Within the San Francisco Bay Area, STS is the most convenient business-aviation field for the northern wine counties, sitting well clear of the congestion at SFO and OAK. Nearby reliever and GA fields — Healdsburg (HES), Petaluma (O69), and Napa County (APC) — handle smaller aircraft, while SFO and OAK remain the heavy-jet and customs alternatives. For travelers headed to Sonoma, Healdsburg, Calistoga, or Napa, KSTS usually offers the shortest drive to the destination.
