Philadelphia to Miami

What the Data Says About PHL to MIA

The Philadelphia to Miami corridor (PHL → MIA) covers roughly 1,013 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 16,803 flights in the dataset, this route posts a 78.4% on-time rate with an average delay of 82.2 minutes when flights run late. Over the most recent 24 months of BTS data, 6,272 flights were recorded on this pairing — 103 cancelled (1.6%) and 21 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 16,803 total flights analyzed, the 78.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.2-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, Nov 2024 posted the best performance on this corridor at 91% on-time, while Jul 2025 came in at 60% on-time — a 31-point gap between best and worst recent month. For travelers evaluating the PHL to MIA route, the combination of a 78.4% on-time rate, 82.2-minute average delay, 1.6% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
