Major events near Denver International Airport (DEN) such as the Great American Beer Festival (October) and the National Western Stock Show (January) can drive up demand and increase economy fares. Sporting events, music festivals, and major conferences in downtown Denver or nearby mountain towns also cause fare spikes. To avoid inflated prices, check event calendars before booking, choose non-event weekends, or fly to alternate airports and drive if feasible.

The best time to fly from Denver International Airport (DEN) to secure cheap economy fares is often during shoulder seasons: late January through early March and mid-September through November. Tuesdays and Wednesdays typically have lower demand and better prices, while early-morning and late-night departures tend to cost less. For domestic routes, book 1–2 months in advance; for international trips or holiday periods, aim for 2–4+ months ahead. Use price tracking and set fare alerts to capture dip opportunities.
