Miami to Philadelphia

What the Data Says About MIA to PHL

The Miami to Philadelphia corridor (MIA → PHL) covers roughly 1,013 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 16,851 flights in the dataset, this route posts a 76.5% on-time rate with an average delay of 83.0 minutes when flights run late. Over the most recent 24 months of BTS data, 6,270 flights were recorded on this pairing — 108 cancelled (1.7%) and 8 diverted (0.1%). 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 16,851 total flights analyzed, the 76.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 83.0-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, Feb 2025 posted the best performance on this corridor at 87% on-time, while Aug 2024 came in at 60% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the MIA to PHL route, the combination of a 76.5% on-time rate, 83.0-minute average delay, 1.7% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
