What the Data Says About OKC to HOU

The Oklahoma City to Houston corridor (OKC → HOU) covers roughly 419 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 7,318 flights in the dataset, this route posts a 84.5% on-time rate with an average delay of 57.7 minutes when flights run late.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,318 total flights analyzed, the 84.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.7-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, Feb 2025 posted the best performance on this corridor at 95% on-time, while Jun 2025 came in at 68% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the OKC to HOU route, the combination of a 84.5% on-time rate, 57.7-minute average delay, 0.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
