That airport is so close to me (about 20 min, I live in Sonoma County as well), I remember several years ago American had Eagle service to SJC. I remember the ticket counter even. Now it's only UA Express to SFO and LAX. I've always thought about having more flights, and it's possible the ones you mentioned would work, but I just don't know.
Apparently I've heard that they are going to build a new airport or something close to the old one, longer runways and all that. I think if anything it should be built a bit further south, it's 5-10 minutes north of Santa Rosa itself in a small town called Windsor.
Head in the clouds... yet feet planted firmly on the ground.
