Denver to Knoxville

What the Data Says About DEN to TYS

The Denver to Knoxville corridor (DEN → TYS) covers roughly 1,162 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 4,614 flights in the dataset, this route posts a 76.4% on-time rate with an average delay of 69.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,887 flights were recorded on this pairing — 13 cancelled (0.7%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,614 total flights analyzed, the 76.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 69.3-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 2025 posted the best performance on this corridor at 94% on-time, while Jul 2025 came in at 53% on-time — a 41-point gap between best and worst recent month. For travelers evaluating the DEN to TYS route, the combination of a 76.4% on-time rate, 69.3-minute average delay, 0.7% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
