Boston to New York

What the Data Says About BOS to JFK

The Boston to New York corridor (BOS → JFK) covers roughly 187 miles and is served by 23 carriers, based on Bureau of Transportation Statistics reporting. Across 30,700 flights in the dataset, this route posts a 80.3% on-time rate with an average delay of 75.5 minutes when flights run late. Over the most recent 24 months of BTS data, 11,110 flights were recorded on this pairing — 295 cancelled (2.7%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 23 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 30,700 total flights analyzed, the 80.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.5-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, Nov 2024 posted the best performance on this corridor at 90% on-time, while Jun 2025 came in at 69% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the BOS to JFK route, the combination of a 80.3% on-time rate, 75.5-minute average delay, 2.7% recent cancellation rate, and 23 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
