Miami to New York

What the Data Says About MIA to JFK

The Miami to New York corridor (MIA → JFK) covers roughly 1,089 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 30,548 flights in the dataset, this route posts a 73.1% on-time rate with an average delay of 84.7 minutes when flights run late. Over the most recent 24 months of BTS data, 10,505 flights were recorded on this pairing — 196 cancelled (1.9%) and 24 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 30,548 total flights analyzed, the 73.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.7-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, Oct 2024 posted the best performance on this corridor at 90% on-time, while Jun 2024 came in at 64% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the MIA to JFK route, the combination of a 73.1% on-time rate, 84.7-minute average delay, 1.9% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
