Burlington to Philadelphia

What the Data Says About BTV to PHL

The Burlington to Philadelphia corridor (BTV → PHL) covers roughly 335 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 3,898 flights in the dataset, this route posts a 82.3% on-time rate with an average delay of 100.0 minutes when flights run late. Over the most recent 24 months of BTS data, 1,933 flights were recorded on this pairing — 59 cancelled (3.1%) and 3 diverted (0.2%). 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 3,898 total flights analyzed, the 82.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 100.0-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, Nov 2024 posted the best performance on this corridor at 89% on-time, while May 2025 came in at 65% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the BTV to PHL route, the combination of a 82.3% on-time rate, 100.0-minute average delay, 3.1% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
