What the Data Says About TYS to DTW

The Knoxville to Detroit corridor (TYS → DTW) covers roughly 443 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 3,206 flights in the dataset, this route posts a 93.3% on-time rate with an average delay of 84.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,016 flights were recorded on this pairing — 8 cancelled (0.8%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,206 total flights analyzed, the 93.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.1-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 2024 posted the best performance on this corridor at 100% on-time, while Jul 2024 came in at 85% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the TYS to DTW route, the combination of a 93.3% on-time rate, 84.1-minute average delay, 0.8% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
