Napa is centrally located near three major airports:
San Francisco International Airport: 60.0 miles
Metropolitan Oakland International: 52.0 miles
Sacramento Executive Airport: 65.0 miles
Presently, no major airport shuttles are operating in the region; however, visit this link from "Trip Savy" that may offer information of interest to you.
If you truly have no desire to drive and are arriving via San Francisco, I would recommend Airporter Express https://airportexpressinc.com/schedule.php to either Petaluma or Doubletree in Rohnert Part and then call for an Uber the remainder of the way. Of course, you can Uber all the way up if you want door-to-door.
For Oakland and Sacramento airports, consider an Uber or taxi.

The drive to Napa is a staff pick. To avoid toll roads near Oakland, consider going on CA 101 N over the Golden Gate Bridge and enjoy the drive of the Carnos wine region.
