Philadelphia to West Palm Beach/Palm Beach

What the Data Says About PHL to PBI

The Philadelphia to West Palm Beach/Palm Beach corridor (PHL → PBI) covers roughly 951 miles and is served by 22 carriers, based on Bureau of Transportation Statistics reporting. Across 8,282 flights in the dataset, this route posts a 75.9% on-time rate with an average delay of 78.4 minutes when flights run late. Over the most recent 24 months of BTS data, 3,272 flights were recorded on this pairing — 66 cancelled (2.0%) and 9 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 22 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,282 total flights analyzed, the 75.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.4-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, Sep 2025 posted the best performance on this corridor at 88% on-time, while Jun 2025 came in at 56% on-time — a 33-point gap between best and worst recent month. For travelers evaluating the PHL to PBI route, the combination of a 75.9% on-time rate, 78.4-minute average delay, 2.0% recent cancellation rate, and 22 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
