Flying to Denver
Denver is the gateway to the Rockies—skiing, hiking, and a growing city scene. Denver International is one of the busiest airports in the country, so you’ll find plenty of options and often good prices.
Getting there
Denver International (DEN) is the main airport, about 25 miles northeast of downtown. It’s a major hub with strong domestic coverage and a growing number of international flights. The train connects the airport to downtown. Use the search form above to compare fares; competition is strong, so flexible dates usually help.
When to fly
Peak times are ski season (December–March) and summer. For better value, look at January–February (non-holiday) or April–May. Tuesday and Wednesday are typically cheaper than weekends.
Denver’s altitude can affect some travelers. If you're heading straight to the mountains, consider an extra night in the city to adjust—and book your flight with that in mind.

Search nearby airports
A nearby airport can be cheaper than the obvious one, especially when a city is served by multiple airports or regional alternatives.
Avoid peak travel days
Friday departures and Sunday returns often cost more. Midweek combinations are usually a better place to start.
Look outside the busiest season
Shoulder-season trips can deliver better fares, shorter lines, and more flexible flight options.
Review the full trip cost
The cheapest headline fare is not always the best value after carry-on fees, seat selection, and airport transfer costs.
