Kansas City to Denver

Round trip
Denver from Kansas City just dropped to $53 round trip nonstop on Frontier, down from the $102 fare we sent a few days ago and about 62% below the typical price on this route. That's actually a touch under the lowest fare we've ever logged here, so double check the fare rules before booking, but at this price a mountain weekend is nearly free. Nonstop, no layovers, easy to slot into any travel calendar.
