You can get their schedule online including how long the trip is and when you can expect to arrive at SFO. Fare is $22 for an adult. I think it's now every hour at 10 min. after the hour from the Transit station. It goes every half hour from the Anderson Drive site. I think the length of the trip is scheduled for about 1.25 to 1.5 hrs.
Katrina is correct. I took the bus from San Rafael to Add airport. It was in time and safe . Great experience
