San Francisco Bay Area to San Diego
$44$20779% off
Round trip
SFO to San Diego tickets typically run about $207, so $44 nonstop on Frontier is a steep cut for one of California's easiest weekend-trip routes. Beaches, the zoo, and Gaslamp Quarter nightlife are all an hour's flight away at this price, part of a wider Frontier sale we're seeing across several hubs right now.
