There is a small airport in Sonoma County, it’s called Charles M. Schulz – Sonoma County Airport (STS).The main airline flying from this airport is Alaskan Airlines with non stop flights to Los Angeles, Portland, San Diego and Seattle.
It is a small airport with plans to expand. Click on this link for more details. This might take a while due to environmental issues. Recently the airport expansion has been in the news with regards to using eminent domain to purchase property needed for this expansion. More about eminent domain in my RE blog.
Last year we flew from Santa Rosa to Los Angeles, this was a pleasant experience. Adding up what it would costs us to fly from San Francisco (parking, gas, toll) it made more sense to fly from our local airport.
And the Airport Express leaves from this airport with services to Oakland and San Francisco airport.
