San Diego to San Francisco
$46$18876% off
Round trip
San Diego to San Francisco just dropped to $46 nonstop on Frontier, compared to the roughly $168 this route usually runs, and it is the cheapest SAN-SFO fare we have ever tracked. It is an easy weekend grab this fall for wine country, the Presidio, and Golden Gate Park, all a short ride from the airport.
