Round trip
This Frontier nonstop from San Diego to San Francisco usually runs about $216, but it's matching our all-time low of $38 right now, an 82% discount. San Francisco's cable cars, food scene, and wine country day trips make it one of the most bookable short hops in California, and this fare is cheap enough to tack onto any West Coast itinerary without a second thought.
