Southwest Airlines Adds Sonoma County Flights April 2026

Southwest Airlines will begin new nonstop flights to Charles M. Schulz Sonoma County Airport in Santa Rosa, California, starting April 7, 2026, expanding its presence in California with this becoming its 14th airport in the state. The airline will offer routes connecting Santa Rosa to San Diego, Las Vegas, Denver, and Burbank, with daily flights to San Diego and Las Vegas, five days per week to Burbank, and Saturdays only to Denver. This expansion aims to provide greater access to California's Wine Country and connect travelers to upgraded terminals at San Diego International Airport and Hollywood Burbank Airport. The move reinforces Southwest's commitment to California, where it operates the most intra-state flights without regional partners. The addition comes as Charles M. Schulz Sonoma County Airport recently experienced a record increase in passengers despite the departure of Avelo Airlines. Tickets for the new routes will be available starting tomorrow, offering a closer base for travelers visiting Sonoma and Napa counties.
