Direct flights from Denver International Airport (DEN) are faster and reduce the risk of missed connections, but connecting itineraries can sometimes deliver significant economy fare savings — especially when mixing legacy and low-cost carriers.

Always allow sufficient layover time for checked luggage transfers and potential delays. CTA: Compare nonstop and one-stop options from DEN to find the lowest economy fare that fits your schedule.
Major carriers like United and Southwest provide extensive route networks from Denver International Airport (DEN) with frequent nonstop flights, while low-cost carriers (e.g., Frontier, Spirit) often offer the lowest base Economy Fare (ECO) but charge separately for seat selection and checked bags.
