New York to Knoxville

What the Data Says About LGA to TYS

The New York to Knoxville corridor (LGA → TYS) covers roughly 647 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 4,441 flights in the dataset, this route posts a 83.6% on-time rate with an average delay of 73.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,220 flights were recorded on this pairing — 72 cancelled (3.2%) and 1 diverted (0.0%). 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 4,441 total flights analyzed, the 83.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.6-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 95% on-time, while May 2025 came in at 66% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the LGA to TYS route, the combination of a 83.6% on-time rate, 73.6-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.
