Officials at Sonoma County's regional airport says they have some big news: Southwest Airlines is starting service here next April.

Airport manager Jon Stout said the airline will begin service with new non-stop routes to San Diego, Burbank, Las Vegas and Denver.

Stout says the move expands the airport’s offerings to include a popular connection for eastbound flights on North America’s fourth largest airline.

“We welcome Southwest Airlines to the North Bay family and are excited about this diversity of new destinations,” said Supervisor James Gore.

Stout said tikets on Southwest flights will be available for purchase starting Sept. 11. Service will begin April 7, 2026.

“I can’t tell you how pleased I am to welcome the newest member of our airline family,” said Airport Manager Jon Stout. “Southwest has long been a heavily requested carrier, and I’m proud to deliver for the people of Sonoma County. I look forward to a long-lasting partnership.”

According to Stout, "the San Diego and Las Vegas routes are set to operate daily, including two San Diego roundtrips on peak days, with Denver and Burbank operating on high-demand days."
