Denver airports

The majority of Denver flights land at Denver Intl. Airport (DEN). This airport, commonly referred to as DIA, is the largest airport in the United States and the second largest in the world. In addition, DIA is home to the longest public use runway in the country, and it is the 11th busiest airport in the world when ranked by passenger traffic. Airlines that have a major presence at DIA include Frontier Airlines, Great Lakes Airlines, United Airlines and Southwest Airlines. DIA is a rather unique looking airport; it's covered by a white Teflon-coated fiberglass roof that resembles the Rocky Mountains in an abstract sort of way. Other airports that service the Denver area include Rocky Mountain Metropolitan Airport, Centennial Airport and Front Range Airport.

When to book your flights to Denver

There's never a bad time to book your tickets to Denver. Many people are under the impression that Denver is a cold and snowy place year-round; they would be mistaken. The weather is generally mild and pleasant in Denver throughout the entire year, even during the middle of the winter. Sure, there might be blizzards once in a while, but once it stops snowing, the snow melts away very quickly thanks to the ever present sunshine. Be sure to book Denver airfare during June through August in order to experience some of the most pleasant weather in the entire country; due to its high altitude, there is little to no humidity during the summer.

When is the best time to buy airline tickets?

From America, regardless of destination, average ticket prices for economy and premium cabins tend to rise as the departure date gets closer. Waiting to book at the last minute can be an expensive gamble. Booking three weeks ahead of a trip is the “sweet spot” for fare savings.

Furthermore, travelers can unlock discounts on the total cost of a trip when they bundle flights and hotel stays, and in some cases with other travel products and experiences. For example, adding a flight to an existing hotel booking through Expedia can result in hotel savings of up to 42%. Terms apply.
