ORD to DEN Flights: Best Deals from the Windy City to the Rockies

To maximize your comfort and efficiency when traveling from Chicago to Denver, it is essential to prepare for the significant elevation change; remember to increase your water intake and avoid strenuous activity during your first 24 hours in Colorado to mitigate potential altitude sickness. When departing from the massive ORD complex, always check real-time security wait times for your specific terminal via the official airport website to ensure a stress-free boarding experience, especially during the hectic early morning rush. Since Denver International Airport is located roughly 25 miles from the city center, the RTD A-Line commuter rail is your most reliable and cost-effective transportation option, offering a smooth 37-minute ride directly to Denver Union Station. Lastly, regardless of the time of year, pack versatile layers of clothing, as Denver is famous for its rapid weather shifts where temperatures can drop or rise by 30 degrees in a single afternoon.

Travelers looking for the lowest fares on the ORD to DEN route should target the shoulder seasons, specifically late October to early November or the month of April, when the transition between summer tourism and winter ski peaks results in reduced demand. Conversely, flight prices typically surge during the December holiday window and the height of July. Booking mid-week, particularly on Tuesdays or Wednesdays, generally offers significant savings compared to the high-demand Friday and Sunday schedules.
