Washington to Burlington

What the Data Says About DCA to BTV

The Washington to Burlington corridor (DCA → BTV) covers roughly 437 miles and is served by 19 carriers, based on Bureau of Transportation Statistics reporting. Across 5,775 flights in the dataset, this route posts a 80.7% on-time rate with an average delay of 75.9 minutes when flights run late. Over the most recent 24 months of BTS data, 2,723 flights were recorded on this pairing — 78 cancelled (2.9%) and 8 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 19 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,775 total flights analyzed, the 80.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.9-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, Sep 2024 posted the best performance on this corridor at 90% on-time, while Dec 2025 came in at 50% on-time — a 40-point gap between best and worst recent month. For travelers evaluating the DCA to BTV route, the combination of a 80.7% on-time rate, 75.9-minute average delay, 2.9% recent cancellation rate, and 19 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
