Nashville to Philadelphia

What the Data Says About BNA to PHL

The Nashville to Philadelphia corridor (BNA → PHL) covers roughly 675 miles and is served by 47 carriers, based on Bureau of Transportation Statistics reporting. Across 14,717 flights in the dataset, this route posts a 81.1% on-time rate with an average delay of 79.3 minutes when flights run late. Over the most recent 24 months of BTS data, 5,488 flights were recorded on this pairing — 86 cancelled (1.6%) and 10 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 47 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 14,717 total flights analyzed, the 81.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.3-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 2024 posted the best performance on this corridor at 90% on-time, while May 2024 came in at 64% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the BNA to PHL route, the combination of a 81.1% on-time rate, 79.3-minute average delay, 1.6% recent cancellation rate, and 47 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
