Round trip
Frontier has Denver to San Juan at $287, 41% off what this route typically runs, though still a stretch from the $171 floor we've seen historically. It's a one-stop itinerary with only one date window confirmed so far, but San Juan's beaches and old town are a solid payoff for the flight.
