Houston to Colorado Springs

What the Data Says About IAH to COS

The Houston to Colorado Springs corridor (IAH → COS) covers roughly 809 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 2,891 flights in the dataset, this route posts a 81.9% on-time rate with an average delay of 78.6 minutes when flights run late. Over the most recent 24 months of BTS data, 893 flights were recorded on this pairing — 13 cancelled (1.5%) and 5 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,891 total flights analyzed, the 81.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.6-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 85% on-time, while Jul 2024 came in at 65% on-time — a 20-point gap between best and worst recent month. For travelers evaluating the IAH to COS route, the combination of a 81.9% on-time rate, 78.6-minute average delay, 1.5% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
