Phoenix to San Francisco
$76$22366% off
Round trip
Phoenix to San Francisco usually runs about $235 and just fell to $76 nonstop on Frontier. Price dropped! We sent this route at $118 less than a week ago, and it's now 36% cheaper than that on top of being 68% off the usual fare. San Francisco's food scene, Golden Gate views, and easy day trips to wine country make it worth grabbing at this price.
