Denver is a place that truly has it all. It has remarkable downtown food and arts along with easy access to the Rocky Mountains and over 300 days of sunshine a year. Getting affordable flight tickets to Denver is the first step to a great trip whether you're heading there to hit the ski slopes, explore Red Rocks Amphitheatre or simply soak up the Mile High City's relaxing energy. The good news is that Denver is among the United States’ well connected cities and finding a great flight deal is very much within reach with the help of HolidayBreakz.
Timing your booking well is a simple way to save money on Denver airfare. For domestic flights, booking 4-8 weeks early usually lands you in the sweet spot. International tourists should try for 3-5 months out to get the lowest Denver fares.
Denver sees two distinct high travel windows: winter ski season from December through March and summer from late June through August when mountain hiking and outdoor festivals attract huge crowds. Denver flight fares during these periods can rise quickly so booking early is important especially if your dates fall within them.
Consider flying in the middle of April through May or in October and early November for the lowest Denver plane ticket prices. These shoulder seasons offer pleasant weather as well as fewer tourists and noticeably cheaper flights. Traveling midweek particularly on Tuesdays or Wednesdays also can be cheaper than high weekend travel days.
Denver has one primary commercial airport serving the region which keeps things straightforward unlike the Bay Area or New York:
Denver International Airport (DEN) is among the USA’s busiest airports and serves as a major hub for United Airlines and Frontier Airlines. Because it functions as a hub, it benefits from strong route competition which helps keep fares competitive across many destinations. It offers direct connections from numerous cities across North America, Europe and beyond.
The airport sits about 25 miles northeast of downtown Denver so include transfer time and ground transport costs when comparing flight options. There are several reliable means to get into Denver which includes rideshares, shuttles or the University of Colorado A Line train.
There are no significant alternative airports close enough to the city to offer a practical comparison but it's always worth checking whether flying into Colorado Springs Airport (COS) which is about 70 miles south and offers meaningful savings particularly if your destination is in the state’s southern part.
A few smart habits can make a real difference when hunting for affordable Denver airfare:
