Denver to Houston

What the Data Says About DEN to HOU

The Denver to Houston corridor (DEN → HOU) covers roughly 883 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 14,920 flights in the dataset, this route posts a 77.4% on-time rate with an average delay of 57.3 minutes when flights run late. Over the most recent 24 months of BTS data, 5,105 flights were recorded on this pairing — 55 cancelled (1.1%) and 30 diverted (0.6%). 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 14,920 total flights analyzed, the 77.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.3-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, Sep 2024 posted the best performance on this corridor at 91% on-time, while Jul 2025 came in at 56% on-time — a 35-point gap between best and worst recent month. For travelers evaluating the DEN to HOU route, the combination of a 77.4% on-time rate, 57.3-minute average delay, 1.1% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
