Major events that affect economy fares include the Great American Beer Festival (Denver), major Broncos home games, Coors Field events, Aspen and Vail ski season peaks, and national holidays. When events are scheduled, economy fares from DEN to event destinations and nearby hubs commonly increase. To avoid high prices, travel outside event windows, use secondary airports, or book farther in advance.
The best time to fly from Denver International Airport (DEN) for cheap economy fares is typically during shoulder seasons—April–May and September–October—when demand is lower and airlines reduce capacity on leisure routes. Midweek departures (Tuesday, Wednesday) and late-night/early-morning flights usually offer lower prices. Book domestic economy flights about 3–6 weeks in advance and international economy about 2–4 months out for the best pricing.
Connecting flights can be significantly cheaper than nonstop economy fares, especially on high-demand routes; however, they add travel time and connection risk. For cheap economy travel, compare total door-to-door time and the full ticket cost including baggage. If time is limited or you value reliability, a nonstop may justify a higher fare. Use reasonable connection times (minimum 60–90 minutes domestic, 90–180 international) when booking the cheapest connections.
Key carriers at DEN for economy travelers: Southwest Airlines — competitive sample fares, free two checked bags on many fares, broad domestic network.

Always compare total trip cost including baggage and seat fees.
Winter: Expect snow delays—book refundable economy or flexible fares if traveling during storms, and prepay baggage for ski gear. Spring (shoulder): Best deals and fewer crowds—target April–May for cheap economy fares. Summer: Peak demand—book early and prefer midweek or secondary airports for savings. Fall: September–October often provide the cheapest economy fares and pleasant travel conditions. Always factor in total trip cost (fare + bags + transfers) when evaluating economy options.
