New York to Martha's Vineyard

What the Data Says About JFK to MVY

The New York to Martha's Vineyard corridor (JFK → MVY) covers roughly 173 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 1,741 flights in the dataset, this route posts a 78.2% on-time rate with an average delay of 84.2 minutes when flights run late. Over the most recent 24 months of BTS data, 1,741 flights were recorded on this pairing — 66 cancelled (3.8%) and 6 diverted (0.3%). 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 1,741 total flights analyzed, the 78.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.2-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, Jun 2021 posted the best performance on this corridor at 86% on-time, while Jul 2021 came in at 67% on-time — a 19-point gap between best and worst recent month. For travelers evaluating the JFK to MVY route, the combination of a 78.2% on-time rate, 84.2-minute average delay, 3.8% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
