Tulsa to Denver

What the Data Says About TUL to DEN

The Tulsa to Denver corridor (TUL → DEN) covers roughly 541 miles and is served by 22 carriers, based on Bureau of Transportation Statistics reporting. Across 11,392 flights in the dataset, this route posts a 82.6% on-time rate with an average delay of 74.2 minutes when flights run late. Over the most recent 24 months of BTS data, 4,580 flights were recorded on this pairing — 30 cancelled (0.7%) and 9 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 22 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 11,392 total flights analyzed, the 82.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.2-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 2024 posted the best performance on this corridor at 92% on-time, while Jul 2025 came in at 66% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the TUL to DEN route, the combination of a 82.6% on-time rate, 74.2-minute average delay, 0.7% recent cancellation rate, and 22 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
