Colorado Springs to Houston

What the Data Says About COS to IAH

The Colorado Springs to Houston corridor (COS → IAH) covers roughly 809 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 2,890 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 88.3 minutes when flights run late. Over the most recent 24 months of BTS data, 893 flights were recorded on this pairing — 10 cancelled (1.1%) and 3 diverted (0.3%). 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 2,890 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.3-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 94% on-time, while Jul 2024 came in at 69% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the COS to IAH route, the combination of a 83.7% on-time rate, 88.3-minute average delay, 1.1% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
