Houston to Denver

What the Data Says About HOU to DEN

The Houston to Denver corridor (HOU → DEN) covers roughly 883 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 14,913 flights in the dataset, this route posts a 81.6% on-time rate with an average delay of 58.5 minutes when flights run late. Over the most recent 24 months of BTS data, 5,114 flights were recorded on this pairing — 63 cancelled (1.2%) and 18 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 14,913 total flights analyzed, the 81.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.5-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, Sep 2024 posted the best performance on this corridor at 90% on-time, while Jun 2025 came in at 67% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the HOU to DEN route, the combination of a 81.6% on-time rate, 58.5-minute average delay, 1.2% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
