West Palm Beach/Palm Beach to Boston

What the Data Says About PBI to BOS

The West Palm Beach/Palm Beach to Boston corridor (PBI → BOS) covers roughly 1,197 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 9,862 flights in the dataset, this route posts a 73.7% on-time rate with an average delay of 84.4 minutes when flights run late. Over the most recent 24 months of BTS data, 4,235 flights were recorded on this pairing — 68 cancelled (1.6%) and 7 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 9,862 total flights analyzed, the 73.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.4-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 90% on-time, while Sep 2025 came in at 45% on-time — a 45-point gap between best and worst recent month. For travelers evaluating the PBI to BOS route, the combination of a 73.7% on-time rate, 84.4-minute average delay, 1.6% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
