Los Angeles to San Francisco
$62$22072% off
Round trip
We flagged Ontario to San Francisco on Frontier a couple days ago at $102, and it just dropped to $62 round trip, nonstop, 79% off the roughly $300 typical fare. This is about as low as this short coastal hop gets, so if a Bay Area weekend has been on the list, this is the price to book at.
