Omaha to Denver

What the Data Says About OMA to DEN

The Omaha to Denver corridor (OMA → DEN) covers roughly 472 miles and is served by 22 carriers, based on Bureau of Transportation Statistics reporting. Across 17,766 flights in the dataset, this route posts a 80.1% on-time rate with an average delay of 70.8 minutes when flights run late. Over the most recent 24 months of BTS data, 6,581 flights were recorded on this pairing — 80 cancelled (1.2%) and 11 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 17,766 total flights analyzed, the 80.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.8-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 86% on-time, while Jun 2025 came in at 64% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the OMA to DEN route, the combination of a 80.1% on-time rate, 70.8-minute average delay, 1.2% recent cancellation rate, and 22 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
