Dayton to Philadelphia

What the Data Says About DAY to PHL

The Dayton to Philadelphia corridor (DAY → PHL) covers roughly 477 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,510 flights in the dataset, this route posts a 90.7% on-time rate with an average delay of 86.1 minutes when flights run late. Over the most recent 24 months of BTS data, 793 flights were recorded on this pairing — 9 cancelled (1.1%) and 1 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,510 total flights analyzed, the 90.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 86.1-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, Jan 2023 posted the best performance on this corridor at 92% on-time, while Nov 2021 came in at 91% on-time — a 2-point gap between best and worst recent month. For travelers evaluating the DAY to PHL route, the combination of a 90.7% on-time rate, 86.1-minute average delay, 1.1% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
