New York to Miami

What the Data Says About LGA to MIA

The New York to Miami corridor (LGA → MIA) covers roughly 1,096 miles and is served by 27 carriers, based on Bureau of Transportation Statistics reporting. Across 30,353 flights in the dataset, this route posts a 76.9% on-time rate with an average delay of 82.8 minutes when flights run late. Over the most recent 24 months of BTS data, 11,748 flights were recorded on this pairing — 262 cancelled (2.2%) and 41 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 27 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 30,353 total flights analyzed, the 76.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.8-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 Dec 2025 came in at 64% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the LGA to MIA route, the combination of a 76.9% on-time rate, 82.8-minute average delay, 2.2% recent cancellation rate, and 27 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
