Key West to Washington

What the Data Says About EYW to DCA

The Key West to Washington corridor (EYW → DCA) covers roughly 1,023 miles and is served by 7 carriers, based on Bureau of Transportation Statistics reporting. Across 2,500 flights in the dataset, this route posts a 76.2% on-time rate with an average delay of 64.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,105 flights were recorded on this pairing — 19 cancelled (1.7%) and 14 diverted (1.3%). Those baseline metrics tell you what to expect before you book.

Having 7 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,500 total flights analyzed, the 76.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 64.8-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, Dec 2025 posted the best performance on this corridor at 84% on-time, while Feb 2025 came in at 66% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the EYW to DCA route, the combination of a 76.2% on-time rate, 64.8-minute average delay, 1.7% recent cancellation rate, and 7 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
