Most people would probably take BART and the Oakland International Airport connector shuttle. (The trip takes about 45 minutes and costs around $10.)
But Delta Airlines offers a new option. Their “Weekly Fare Specials” newsletters alerts travelers to the special fare of $69 from SFO to OAK.
You will go through Salt Lake City, where you will have about an hour layover. Your total time for the trip will be around four hours, not counting the usual air travel issues of security and the like.
Such a deal!
