Key West to Miami

What the Data Says About EYW to MIA

The Key West to Miami corridor (EYW → MIA) covers roughly 126 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 7,150 flights in the dataset, this route posts a 81.5% on-time rate with an average delay of 65.5 minutes when flights run late. Over the most recent 24 months of BTS data, 2,587 flights were recorded on this pairing — 49 cancelled (1.9%) and 1 diverted (0.0%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,150 total flights analyzed, the 81.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.5-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, Oct 2024 posted the best performance on this corridor at 93% on-time, while Mar 2024 came in at 64% on-time — a 29-point gap between best and worst recent month. For travelers evaluating the EYW to MIA route, the combination of a 81.5% on-time rate, 65.5-minute average delay, 1.9% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
