Boston to West Palm Beach/Palm Beach

What the Data Says About BOS to PBI

The Boston to West Palm Beach/Palm Beach corridor (BOS → PBI) covers roughly 1,197 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 9,865 flights in the dataset, this route posts a 70.5% on-time rate with an average delay of 76.0 minutes when flights run late. Over the most recent 24 months of BTS data, 4,240 flights were recorded on this pairing — 61 cancelled (1.4%) and 21 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,865 total flights analyzed, the 70.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.0-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).

Looking at recent months, Oct 2024 posted the best performance on this corridor at 84% on-time, while Dec 2024 came in at 54% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the BOS to PBI route, the combination of a 70.5% on-time rate, 76.0-minute average delay, 1.4% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
