Charlotte to Philadelphia

What the Data Says About CLT to PHL

The Charlotte to Philadelphia corridor (CLT → PHL) covers roughly 449 miles and is served by 13 carriers, based on Bureau of Transportation Statistics reporting. Across 19,904 flights in the dataset, this route posts a 78.3% on-time rate with an average delay of 78.0 minutes when flights run late. Over the most recent 24 months of BTS data, 7,630 flights were recorded on this pairing — 146 cancelled (1.9%) and 11 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 13 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 19,904 total flights analyzed, the 78.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 78.0-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, Sep 2025 posted the best performance on this corridor at 81% on-time, while Jul 2024 came in at 55% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the CLT to PHL route, the combination of a 78.3% on-time rate, 78.0-minute average delay, 1.9% recent cancellation rate, and 13 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
