Why this is a deal
Because $38 round trip for a nonstop route is borderline “price glitch energy.” Even when Denver is cheap, it’s usually nowhere near this. This is the kind of fare that disappears fast once people notice.
Why go then (best time to be there)
Early March in Denver is a sweet spot: winter is still doing its thing, the city has that crisp, cozy feel, and it’s an easy weekend reset that feels way bigger than the time you spend traveling (because nonstop + short flight).
Quick Tips (keep it simple)
Frontier check: double-check bag + seat add-ons before checkout (that’s how ultra-low fares work).
Be flexible: try the two date windows above—often one holds the lowest price longer.
Book first, plan after: at $38 RT, the flight is the hard part—everything else is optional.
