Louisville to New York

What the Data Says About SDF to LGA

The Louisville to New York corridor (SDF → LGA) covers roughly 659 miles and is served by 14 carriers, based on Bureau of Transportation Statistics reporting. Across 7,086 flights in the dataset, this route posts a 85.6% on-time rate with an average delay of 80.7 minutes when flights run late. Over the most recent 24 months of BTS data, 2,939 flights were recorded on this pairing — 56 cancelled (1.9%) and 7 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 14 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,086 total flights analyzed, the 85.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 80.7-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, Sep 2024 posted the best performance on this corridor at 95% on-time, while Dec 2025 came in at 71% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the SDF to LGA route, the combination of a 85.6% on-time rate, 80.7-minute average delay, 1.9% recent cancellation rate, and 14 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
