Philadelphia to Burlington

What the Data Says About PHL to BTV

The Philadelphia to Burlington corridor (PHL → BTV) covers roughly 335 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 3,899 flights in the dataset, this route posts a 81.1% on-time rate with an average delay of 84.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,932 flights were recorded on this pairing — 46 cancelled (2.4%) and 10 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 3,899 total flights analyzed, the 81.1% on-time figure is statistically meaningful rather than a small-sample fluke. The 84.9-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, Oct 2023 posted the best performance on this corridor at 93% on-time, while Aug 2024 came in at 62% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the PHL to BTV route, the combination of a 81.1% on-time rate, 84.9-minute average delay, 2.4% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
