Phoenix to Colorado Springs

What the Data Says About PHX to COS

The Phoenix to Colorado Springs corridor (PHX → COS) covers roughly 551 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 5,196 flights in the dataset, this route posts a 77.4% on-time rate with an average delay of 54.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,970 flights were recorded on this pairing — 6 cancelled (0.3%) and 10 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,196 total flights analyzed, the 77.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 54.7-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, Feb 2025 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 60% on-time — a 35-point gap between best and worst recent month. For travelers evaluating the PHX to COS route, the combination of a 77.4% on-time rate, 54.7-minute average delay, 0.3% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
