Denver to Nashville

What the Data Says About DEN to BNA

The Denver to Nashville corridor (DEN → BNA) covers roughly 1,014 miles and is served by 23 carriers, based on Bureau of Transportation Statistics reporting. Across 21,238 flights in the dataset, this route posts a 77.4% on-time rate with an average delay of 59.8 minutes when flights run late. Over the most recent 24 months of BTS data, 7,788 flights were recorded on this pairing — 58 cancelled (0.7%) and 24 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 23 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 21,238 total flights analyzed, the 77.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 59.8-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 90% on-time, while Jun 2025 came in at 60% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the DEN to BNA route, the combination of a 77.4% on-time rate, 59.8-minute average delay, 0.7% recent cancellation rate, and 23 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
