Denver to San Diego
$85$22061% off
Round trip
Denver to San Diego usually runs about $257 round trip, and Frontier just dropped it to $85, a 67% cut on a nonstop hop. San Diego's beaches, Balboa Park, and craft breweries make this one of the easiest weekend trips to book on a whim, and at this price it barely touches the budget.
