West Palm Beach/Palm Beach to Philadelphia

What the Data Says About PBI to PHL

The West Palm Beach/Palm Beach to Philadelphia corridor (PBI → PHL) covers roughly 951 miles and is served by 21 carriers, based on Bureau of Transportation Statistics reporting. Across 8,297 flights in the dataset, this route posts a 77.8% on-time rate with an average delay of 105.2 minutes when flights run late. Over the most recent 24 months of BTS data, 3,270 flights were recorded on this pairing — 68 cancelled (2.1%) and 6 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 21 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 8,297 total flights analyzed, the 77.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 105.2-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 87% on-time, while Aug 2024 came in at 50% on-time — a 37-point gap between best and worst recent month. For travelers evaluating the PBI to PHL route, the combination of a 77.8% on-time rate, 105.2-minute average delay, 2.1% recent cancellation rate, and 21 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
