Visit the Mile-High City

Denver, fondly known as the Mile-High City due to its high altitude, is a beautiful city located near the Rocky Mountains. Most people don't realize this, but Denver is a very sunny city; on average, it's sunny here 300 days a year. People love visiting Denver in order to see the majestic mountains and breathe in the fresh air. Denver is a city for all seasons; in the winter, people go snowboarding and skiing, and in the summer, they hike in the mountains and enjoy the view. Get ready to enjoy this Queen City of the West by booking your cheap flights to Denver on Expedia.com today.

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.

Do you have any tips for my flight to Denver?

  • What you pack in your hand luggage can be the difference between a comfortable flight, and one that leaves you drained. Start with the must-haves, such as a valid ID (like your passport) and your travel documents. Once they’re packed, throw in any medications you might need. Next, think about comfort factor. A quality neck pillow, earphones and the latest bestseller will help the time fly by while you’re soaring through the sky.
  • Remember that there’s also a list of prohibited items for your hand luggage which differs between carriers. As a general rule, avoid carrying anything explosive, flammable or sharp. This includes things like razor blades, utility knives, aerosol cans and flares. Sporting equipment like baseball bats, ski poles and objects considered weapons, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

  • Whether traveling short or long-haul, layering up is key to staying comfortable. Choose loose, natural fabrics that will keep you cool and pack a pullover for any in-flight temperature changes. Your feet will be happiest in a pair of sneakers or flat shoes.
  • The condition known as deep vein thrombosis (DVT) is a risk on long-haul flights. It’s the result of blood clotting due to inactivity and poor circulation. Wandering up and down the aisle and doing leg and foot stretches while seated can help prevent this developing. Wearing compression socks or tights can also help to reduce your risk.

How can I get a cheap last-minute flight to Denver?
Picking up a cheap, spur-of-the-moment flight to Denver is as simple as having some flexibility with your travel plans. Keep your options open when it comes to your travel dates, flight times and choice of airline. If your destination has a few airports, compare the prices of jetting into each of them for the best deal.
Where can I learn more about changing or canceling my flight to Denver?
Most flights are free to cancel within 24 hours of making the reservation. However, some flights are non-refundable, and you may receive a flight credit from the airline to use for a future booking. For more information, please visit our Customer Service Portal.
