New York to Martha's Vineyard

What the Data Says About LGA to MVY

The New York to Martha's Vineyard corridor (LGA → MVY) covers roughly 175 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 1,299 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 69.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,299 flights were recorded on this pairing — 40 cancelled (3.1%) and 2 diverted (0.2%). 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 1,299 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 69.3-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, Aug 2025 posted the best performance on this corridor at 90% on-time, while Aug 2024 came in at 74% on-time — a 16-point gap between best and worst recent month. For travelers evaluating the LGA to MVY route, the combination of a 82.2% on-time rate, 69.3-minute average delay, 3.1% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
