Denver serves as the gateway to some of America's greatest outdoor experiences — Rocky Mountain National Park, world-class ski resorts, hiking, cycling, and the vibrant city itself at 5,280 feet. Denver International Airport (DIA) is one of the largest airports in the world by area and serves virtually every major US airline.

Frontier Airlines is headquartered in Denver and offers extensive service from Denver to cities across the US. United Airlines has a major hub at DIA. Southwest, American, Delta, Alaska, and others also serve Denver extensively. This competition generally keeps Denver flight prices competitive.

Ski season (December-March) is the most expensive time to fly to Denver, particularly around Christmas, New Year's, and President's Day weekend. If skiing is your goal but budget matters, target early December or late March when resort conditions are still good but crowds (and prices) are lower.

Summer (June-August) sees high demand from hikers and outdoor enthusiasts but prices are more moderate than ski season. Fall (September-October) is spectacular for foliage and offers some of the best flight deals combined with excellent weather for outdoor activities.
