Key West to Atlanta

What the Data Says About EYW to ATL

The Key West to Atlanta corridor (EYW → ATL) covers roughly 646 miles and is served by 5 carriers, based on Bureau of Transportation Statistics reporting. Across 9,309 flights in the dataset, this route posts a 83.7% on-time rate with an average delay of 89.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,928 flights were recorded on this pairing — 49 cancelled (1.7%) and 13 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 5 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,309 total flights analyzed, the 83.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.6-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, Aug 2024 posted the best performance on this corridor at 95% on-time, while Mar 2025 came in at 69% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the EYW to ATL route, the combination of a 83.7% on-time rate, 89.6-minute average delay, 1.7% recent cancellation rate, and 5 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
