After flying here several times on a budget, I’ve learned the best tricks for finding affordable flights, and I’m sharing those insider tips in this guide.
For this post, I analyzed 165 flight routes to find the 9 cheapest airports to fly into Colorado in 2025. From major hubs like Denver International to regional gems like Colorado Springs, Grand Junction, and Montrose, these airports offer affordable access to Colorado’s top spots. So, if you’re ready to dive into the Rockies without overspending, here’s where to land to kick off your Colorado vacation!
#1 tip to find cheap flights to Colorado
For the past 4 years, I’ve used Scott’s Cheap Flights (now called Going) to get amazing flight deals. All you have to do is enter your home airport and where you want to go, and from there, they’ll send you mistake fares and other ridiculously cheap flight deals. And the coolest part? It’s 100% FREE! In 2024, I’ve saved thousands of dollars from their email alerts. This includes most recently, a $172 roundtrip fare from Boston to Denver.
There’s a free and a premium version – the free one has pretty much everything you’ll need. Though if you’re like me and travel a lot, it’s worth upgrading to the paid version for $49 per year. I recommend signing up for the free trial (you can cancel at any time) to try it for yourself. And if you like it, use my coupon code JON20 to save 20%!
Now without further ado, here are the best Colorado flights in 2025.

Denver International is one of the best airports to fly into if you’re visiting Colorado on a budget. Frontier’s hub status here means flights regularly dip below $60 one-way from most US airports.

Once you land, you’re less than 40 minutes from downtown. From there, explore hotspots in Denver like Union Station, Larimer Square, and the Denver Art Museum. Red Rocks Amphitheatre is only a short drive away and makes for an epic sunset hike or concert venue. And if you’re up for a day trip, Rocky Mountain National Park is just 90 minutes out…packed with scenic drives, alpine lakes, and mountain trails.
Fun fact: Denver International is the largest airport in North America by land area…it’s practically its own city. The city is a super convenient and affordable launchpad for exploring Colorado’s best cities, mountains, and national parks.
