Denver to Colorado Springs

What the Data Says About DEN to COS

The Denver to Colorado Springs corridor (DEN → COS) covers roughly 73 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 22,901 flights in the dataset, this route posts a 75.9% on-time rate with an average delay of 70.6 minutes when flights run late. Over the most recent 24 months of BTS data, 10,310 flights were recorded on this pairing — 152 cancelled (1.5%) and 15 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 13 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 22,901 total flights analyzed, the 75.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.6-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, Oct 2024 posted the best performance on this corridor at 89% on-time, while Jul 2025 came in at 60% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the DEN to COS route, the combination of a 75.9% on-time rate, 70.6-minute average delay, 1.5% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
