Colorado Springs to Phoenix

What the Data Says About COS to PHX

The Colorado Springs to Phoenix corridor (COS → PHX) covers roughly 551 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 5,226 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 68.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,966 flights were recorded on this pairing — 5 cancelled (0.3%) and 3 diverted (0.2%). 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 5,226 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.0-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 93% on-time, while Dec 2025 came in at 70% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the COS to PHX route, the combination of a 82.2% on-time rate, 68.0-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.
