Book domestic economy tickets 6–8 weeks in advance and international economy seats 2–4 months out; monitor fare calendars and sign up for alerts to catch flash sales.

Choosing nonstop flights from Denver International Airport (DEN) reduces travel time and the risk of missed connections, but connecting itineraries often provide the cheapest economy fares due to competition and routing.

When opting for connections, allow sufficient layover time—especially during winter months when delays are more likely.

Consider total trip cost including ancillaries when comparing.

Winter: Pack warm layers, allow extra time for road travel to DEN, and book earlier to hedge against cancellations; consider travel insurance for snow-prone months. Spring: Use shoulder-season discounts and plan for variable weather; midweek travel often saves money. Summer: Expect peak crowds—book accommodations and airport parking ahead. Fall: Enjoy quieter travel and lower fares; leaf-peeping near the Rockies is popular, so reserve transfers early. For all seasons, carry essentials in a carry-on and check airline baggage rules when choosing cheapest ECO fares.
