Oklahoma City to Denver

What the Data Says About OKC to DEN

The Oklahoma City to Denver corridor (OKC → DEN) covers roughly 495 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 16,301 flights in the dataset, this route posts a 79.9% on-time rate with an average delay of 72.2 minutes when flights run late. Over the most recent 24 months of BTS data, 6,274 flights were recorded on this pairing — 47 cancelled (0.7%) and 11 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 17 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 16,301 total flights analyzed, the 79.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 72.2-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, Nov 2025 posted the best performance on this corridor at 90% on-time, while Jun 2025 came in at 62% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the OKC to DEN route, the combination of a 79.9% on-time rate, 72.2-minute average delay, 0.7% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
