Round trip
San Francisco usually runs about $299 round trip from Ontario, and today it's an almost unbelievable $38 nonstop on Frontier, an 87% discount that appears to be a new all time low for this route. With plenty of weekend availability over the coming months, this is about as cheap as West Coast flying gets.
