New York to Key West

What the Data Says About LGA to EYW

The New York to Key West corridor (LGA → EYW) covers roughly 1,207 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 1,585 flights in the dataset, this route posts a 79.4% on-time rate with an average delay of 64.5 minutes when flights run late. Over the most recent 24 months of BTS data, 1,043 flights were recorded on this pairing — 18 cancelled (1.7%) and 12 diverted (1.2%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,585 total flights analyzed, the 79.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 64.5-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, Apr 2025 posted the best performance on this corridor at 92% on-time, while Mar 2025 came in at 66% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the LGA to EYW route, the combination of a 79.4% on-time rate, 64.5-minute average delay, 1.7% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
