Key West to Newark

What the Data Says About EYW to EWR

The Key West to Newark corridor (EYW → EWR) covers roughly 1,196 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 3,449 flights in the dataset, this route posts a 73.5% on-time rate with an average delay of 88.2 minutes when flights run late. Over the most recent 24 months of BTS data, 918 flights were recorded on this pairing — 20 cancelled (2.2%) and 15 diverted (1.6%). 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 3,449 total flights analyzed, the 73.5% 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, Dec 2023 posted the best performance on this corridor at 90% on-time, while May 2024 came in at 75% on-time — a 15-point gap between best and worst recent month. For travelers evaluating the EYW to EWR route, the combination of a 73.5% on-time rate, 88.2-minute average delay, 2.2% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
