Phoenix to San Francisco
$43$26284% off
Round trip
Even cheaper now! We recently saw Phoenix to San Francisco at $68, and Frontier has dropped it further to just $43 round trip nonstop, 84% off the roughly $267 this route usually costs. This looks like part of a broader Frontier flash sale hitting the Southwest this week, alongside similarly steep drops from Denver and Las Vegas, and San Francisco's food scene and bay views are hard to beat at this price.
