Chicago to Colorado Springs

What the Data Says About MDW to COS

The Chicago to Colorado Springs corridor (MDW → COS) covers roughly 917 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,867 flights in the dataset, this route posts a 80.4% on-time rate with an average delay of 58.8 minutes when flights run late. Over the most recent 24 months of BTS data, 877 flights were recorded on this pairing — 5 cancelled (0.6%) and 3 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,867 total flights analyzed, the 80.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.8-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Jul 2025 posted the best performance on this corridor at 74% on-time, while Jul 2023 came in at 45% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the MDW to COS route, the combination of a 80.4% on-time rate, 58.8-minute average delay, 0.6% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
