Key West to Boston

What the Data Says About EYW to BOS

The Key West to Boston corridor (EYW → BOS) covers roughly 1,373 miles and is served by 4 carriers, based on Bureau of Transportation Statistics reporting. Across 666 flights in the dataset, this route posts a 75.2% on-time rate with an average delay of 99.0 minutes when flights run late. Over the most recent 24 months of BTS data, 666 flights were recorded on this pairing — 14 cancelled (2.1%) and 44 diverted (6.6%). Those baseline metrics tell you what to expect before you book.

Having 4 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 666 total flights analyzed, the 75.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 99.0-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).

Monthly performance varies, so review the monthly table above to see specific periods. For travelers evaluating the EYW to BOS route, the combination of a 75.2% on-time rate, 99.0-minute average delay, 2.1% recent cancellation rate, and 4 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
