What the Data Says About TYS to PIE

The Knoxville to St. Petersburg corridor (TYS → PIE) covers roughly 550 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,527 flights in the dataset, this route posts a 74.3% on-time rate with an average delay of 88.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,015 flights were recorded on this pairing — 17 cancelled (1.7%) and 7 diverted (0.7%). 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 1,527 total flights analyzed, the 74.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 88.2-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, Jun 2025 posted the best performance on this corridor at 79% on-time, while Jun 2024 came in at 67% on-time — a 12-point gap between best and worst recent month. For travelers evaluating the TYS to PIE route, the combination of a 74.3% on-time rate, 88.2-minute average delay, 1.7% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
