When planning a trip to Colorado’s capital, most travelers wonder, “
What is the cheapest time of year to fly to Denver? Denver is a year-round destination, but airfare prices can vary dramatically depending on the season. If you want the biggest savings, the most affordable months to fly are January, February, and early March.
Why is this period the best? It all comes down to demand. After the December holidays, travel traffic drops sharply. People return to work, kids go back to school, and tourism slows. Airlines reduce fares during this lull to encourage more bookings, making it a golden window for budget travelers.
Denver winters can be chilly, but that works in your favor. Cold weather means fewer tourists, cheaper hotels, and quiet attractions. Even popular spots like Red Rocks Amphitheatre, Union Station, and the Denver Art Museum see lighter crowds—perfect for travelers who want both savings and peace.
In February and early March, you’ll notice gradual price increases, especially as spring break approaches. Still, flights remain cheaper than summer or fall. To make the most of these savings, try booking flights 4–6 weeks in advance. Flying midweek—particularly Tuesdays and Wednesdays—almost always gives you the best fares.
If you want cheap flights outside winter, another small window happens in late April and early May. This “shoulder season” offers moderate weather and fewer tourists before summer crowds arrive. Prices won’t be as low as winter, but they’re still lower than peak months.
Avoid June through August if you're on a tight budget. Summer is Denver’s peak season for hiking, festivals, and road trips. Airfare, hotel rates, and rental cars all climb significantly. The holiday season in November–December is another high-fare period.
So, what is the cheapest time of year to fly to Denver? Without question, it’s January through early March. If you want the lowest prices, the smallest crowds, and a quieter travel experience, winter is the time to book your Denver adventure.
