When to Book Cheap Airline Tickets

Timing is everything when it comes to snagging cheap flights. For the Chicago to Denver route, the sweet spot for booking often falls between 1 to 3 months in advance. While last minute deals can sometimes pop up, relying on them is a gamble.

Consider traveling during the shoulder seasons (spring and fall) for potentially lower fares and fewer crowds.

Beyond booking in advance, here are a few more ways to save money on your Chicago to Denver flight:

  • Be Flexible with Dates: If your travel dates are flexible, use our flexible date search to identify the cheapest days to fly. Mid-week flights are often more affordable than weekend travel.
  • Consider Connecting Flights: While direct flights are convenient, flights with one stop can sometimes offer significant savings. Weigh the extra travel time against the cost.
  • Sign Up for Alerts: Set up fare alerts for your desired route. We'll notify you when prices drop, so you never miss a deal on cheap airline tickets.
  • Fly During Off-Peak Hours: Early morning or late evening flights can sometimes be cheaper.

Baggage and Transit Advice

Before you book, always check the baggage policies of the airline you choose. Carry-on and checked baggage fees can vary significantly, and these costs can add up. Most budget carriers have stricter rules, so factor these into the total cost when comparing ticket prices. For transit in Denver, the RTD Rail system provides convenient connections from Denver International Airport (DEN) to downtown, offering an affordable alternative to taxis or ride-shares.

Direct vs. Connecting Flights

Choosing between a direct and a connecting flight depends on your priorities. Direct flights offer the quickest and most convenient way to travel, minimizing travel time and the risk of missed connections. However, they are often more expensive. Connecting flights can save you money, but they add time to your journey and require careful planning to ensure smooth transitions between flights. If your primary goal is to buy cheap airline tickets and you don't mind a bit of extra travel time, a connecting flight is a great option.
