Knoxville to New York

What the Data Says About TYS to LGA

The Knoxville to New York corridor (TYS → LGA) covers roughly 647 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 4,440 flights in the dataset, this route posts a 86.2% on-time rate with an average delay of 89.0 minutes when flights run late. Over the most recent 24 months of BTS data, 2,220 flights were recorded on this pairing — 70 cancelled (3.2%) and 8 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 4,440 total flights analyzed, the 86.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.0-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 2023 posted the best performance on this corridor at 94% on-time, while Jun 2025 came in at 71% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the TYS to LGA route, the combination of a 86.2% on-time rate, 89.0-minute average delay, 3.2% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
