Round trip
San Diego usually runs well above $210 out of DCA, and this one-stop Frontier fare lands right near the cheapest we've tracked on this route. It's a great way to cover the coast-to-coast trip for beaches, breweries, and better weather without paying premium nonstop pricing. Booking windows are open now, so there's plenty of runway to plan around it.
