What the Data Says About CLT to TYS

The Charlotte to Knoxville corridor (CLT → TYS) covers roughly 177 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 11,170 flights in the dataset, this route posts a 79.5% on-time rate with an average delay of 68.1 minutes when flights run late. Over the most recent 24 months of BTS data, 3,800 flights were recorded on this pairing — 52 cancelled (1.4%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 11,170 total flights analyzed, the 79.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 68.1-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 89% on-time, while May 2024 came in at 61% on-time — a 28-point gap between best and worst recent month. For travelers evaluating the CLT to TYS route, the combination of a 79.5% on-time rate, 68.1-minute average delay, 1.4% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
