Dallas/Fort Worth to Knoxville

What the Data Says About DFW to TYS

The Dallas/Fort Worth to Knoxville corridor (DFW → TYS) covers roughly 772 miles and is served by 31 carriers, based on Bureau of Transportation Statistics reporting. Across 8,303 flights in the dataset, this route posts a 75.1% on-time rate with an average delay of 80.4 minutes when flights run late. Over the most recent 24 months of BTS data, 3,052 flights were recorded on this pairing — 75 cancelled (2.5%) and 4 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 31 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,303 total flights analyzed, the 75.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 80.4-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, Feb 2024 posted the best performance on this corridor at 85% on-time, while Jun 2025 came in at 53% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the DFW to TYS route, the combination of a 75.1% on-time rate, 80.4-minute average delay, 2.5% recent cancellation rate, and 31 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
