Miami to New York

What the Data Says About MIA to LGA

The Miami to New York corridor (MIA → LGA) covers roughly 1,096 miles and is served by 28 carriers, based on Bureau of Transportation Statistics reporting. Across 30,316 flights in the dataset, this route posts a 75.4% on-time rate with an average delay of 74.3 minutes when flights run late. Over the most recent 24 months of BTS data, 11,726 flights were recorded on this pairing — 265 cancelled (2.3%) and 96 diverted (0.8%). Those baseline metrics tell you what to expect before you book.

Having 28 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 30,316 total flights analyzed, the 75.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 74.3-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, Oct 2024 posted the best performance on this corridor at 86% on-time, while Aug 2024 came in at 60% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the MIA to LGA route, the combination of a 75.4% on-time rate, 74.3-minute average delay, 2.3% recent cancellation rate, and 28 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
