Top tips for finding a cheap flight to Colorado

Book in the Goldilocks Window

While there’s no specific day of the week when airline tickets are magically cheaper, we do have recommendations for how far in advance you should plan a trip to find the best deals. We call this booking period the Goldilocks Window because it’s not too early but not too late. It falls 1–3 months before a domestic trip and 2–8 months before an international trip.

However, if you’re booking during peak travel season, like summer or January–February (ski season) in Colorado, it’s best to look even earlier. Search for summer travel in December or January and winter tickets in July.

Waiting until the last minute will cost you money. Last-minute deals are few and far between during busy travel seasons, with fare jumps happening 21, 14, and 7 days ahead of departure dates, so book before then if you can.

Use the Greek Islands Trick

The aptly named Greek Islands Trick may be named for the Greek islands, but it can work for Colorado and other destinations as well. The point of it is to get close to your destination for the cheapest price, then figure out alternative transit for the final leg.

So, if you want to fly from Charlotte to Aspen in January but prices are upwards of $600, you could instead look for flights from Charlotte to Denver. From there, you could rent a car or find a budget airline flight. It takes more planning and effort, but it could save you a couple hundred bucks that you could put toward your ski pass.

Search alternative departure airports

This trick works like the Greek Islands Trick but on the departure side. If you want to fly to Colorado from Madison in June but tickets are out of your price range, check out flights from Milwaukee or Chicago instead. Yes, you’ll have to take a bus or drive, but the savings can be worth it.

Fly when it’s cheaper

Colorado gets very busy in the summer and winter—and for good reason. The hiking and skiing are some of the best in the world, and kids have summer and winter breaks so families can travel. But, more people traveling means airlines can charge more for flights.

We love traveling during shoulder seasons, the periods just on the edges of high seasons; think April–May and late September–early November in Colorado. You’ll still get nice weather, but you’ll also avoid crowds and high prices. If you are going to travel during peak season, you can still save money by flying on Tuesdays, Wednesdays, and Saturdays. Fridays and Sundays are generally the most expensive days to fly.

Set alerts for specific trips

Keeping track of airfare as it fluctuates is exhausting; it’s also maddening when you miss a deal. The good news is there are easy ways to make technology do the work for you.

Set up fare alerts for your travel dates, and you’ll get an email when the price drops into your target range or by a noteworthy amount. We recommend doing this ahead of the Goldilocks Window we mentioned above so you can see deals that come up during that time. And if your departure airports or dates are flexible, set a couple of alerts to cover your bases.

Colorado is easily accessible from within the US. It’s centrally located, with one of the biggest airports in the world. Most visitors to Denver can find a nonstop or one-stop flight, and if you’re visiting elsewhere in Colorado, it’s usually a quick connection.

Frequently asked questions about flying to Colorado

When is the high season in Colorado?

Colorado has two high seasons: summer and winter. People flock to the Centennial State from June to September to hike in national and state parks, as well as from mid-December to March for skiing.

When is the best time to visit Colorado?

The best time to visit Colorado depends on what you like to do. If you want to hike in the national parks and are hoping for warm weather, the best time to visit is from June to early September. If you want to ski, there will likely always be good snow in January and February. Ski season can run much longer, from November to April, but snow isn’t as reliable as you get farther from January and February.

Some people visit Colorado specifically for its vibrant wildflower season, which is hard to predict but generally runs from May to August. June or July is probably your best bet if you want to guarantee seeing wildflowers. All of this said, these times are also the busiest in Colorado and therefore the most expensive.

If you want to save money, travel during shoulder seasons: April–May and October–November. The weather won’t be as warm—or as snowy, depending on the season—but there will likely still be plenty of gorgeous days and the prices will be cheaper. If you’re visiting to see the sights in Denver and outdoor activities aren’t a high priority, you can save money by traveling during these times. And if you do want to spend time outdoors, traveling on the edges of high season can still save you a bit compared with at the height of those seasons.

How many airports are there in Colorado?

Denver International Airport (DEN) is by far the largest and busiest airport in Colorado. But visitors can also fly into Durango-La Plata County Airport (DRO), and Eagle County Regional Airport (EGE) is likely where you’ll fly into if you’re visiting Vail. Grand Junction Airport (GJT), Colorado Springs Airport (COS), and Aspen/Pitkin County Airport (ASE) are other options.

Which city in Colorado is the easiest to get to?

Denver is the easiest city to reach in Colorado, and many flights to regional airports will stop at Denver International Airport. The airport is one of the largest in the world, with nonstop flights to more than 200 destinations worldwide.

What are the rules for traveling with pets to Colorado?

If you’re traveling from within the US, you’ll have to follow rules from your airline and the airports you’re departing from or transiting through. Most airlines and airports require pets to remain in carriers, for example. If you’re visiting from outside the US, requirements vary based on the country you’re coming from. There are vaccination requirements, testing, and other specifications depending on the type of animal. The USDA lists regulations based on the type of animal and home country.

How long is the flight to Colorado?

Colorado is pretty central within the US, but the flight length depends on where you’re coming from. From the East Coast, whether you’re coming from New York or Miami, the flight is about 4.5 hours. From Atlanta, it’s about 3 hours, and from Chicago, Texas, LA, or San Francisco, it’s about 2.5. Add an extra hour or so if you’re headed to Vail or Aspen.

If you’re visiting Colorado from Europe, your flight will range from 9–11 hours. From Mexico City, it’s about 6.5 hours, and from much of South America it’s more than 15 hours with a stop. You can get from Tokyo to Denver in about 11 hours, Istanbul to Denver in about 15, and South Africa to Denver in about 22 hours with a stop.

Denver International Airport is one of the largest airports in the world, and most travelers can reach it on a nonstop or one-stop flight. If you’re visiting elsewhere in Colorado, you’ll likely make at least one stop.
