Houston to Tulsa

What the Data Says About IAH to TUL

The Houston to Tulsa corridor (IAH → TUL) covers roughly 429 miles and is served by 17 carriers, based on Bureau of Transportation Statistics reporting. Across 5,351 flights in the dataset, this route posts a 83.2% on-time rate with an average delay of 73.7 minutes when flights run late. Over the most recent 24 months of BTS data, 1,818 flights were recorded on this pairing — 17 cancelled (0.9%) and 3 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 5,351 total flights analyzed, the 83.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.7-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, Oct 2024 posted the best performance on this corridor at 91% on-time, while Jun 2023 came in at 66% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the IAH to TUL route, the combination of a 83.2% on-time rate, 73.7-minute average delay, 0.9% recent cancellation rate, and 17 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
