San Francisco Bay Area to San Diego
$38$20782% off
Round trip
San Francisco to San Diego is down to $38 nonstop on Frontier, about 82% below the usual price for this hop. That is one of the cheapest California city pairs we track, perfect for a quick beach weekend at the zoo, Balboa Park, or the coast, with seats showing for trips into the fall. At this price it barely costs more than a tank of gas.
