Philadelphia to Dayton

What the Data Says About PHL to DAY

The Philadelphia to Dayton corridor (PHL → DAY) covers roughly 477 miles and is served by 2 carriers, based on Bureau of Transportation Statistics reporting. Across 1,539 flights in the dataset, this route posts a 79.4% on-time rate with an average delay of 84.8 minutes when flights run late. Over the most recent 24 months of BTS data, 792 flights were recorded on this pairing — 13 cancelled (1.6%) and 2 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 2 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,539 total flights analyzed, the 79.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.8-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 90% on-time, while Nov 2021 came in at 85% on-time — a 5-point gap between best and worst recent month. For travelers evaluating the PHL to DAY route, the combination of a 79.4% on-time rate, 84.8-minute average delay, 1.6% recent cancellation rate, and 2 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
