Huntsville to Washington

What the Data Says About HSV to DCA

The Huntsville to Washington corridor (HSV → DCA) covers roughly 613 miles and is served by 11 carriers, based on Bureau of Transportation Statistics reporting. Across 6,260 flights in the dataset, this route posts a 76.9% on-time rate with an average delay of 85.9 minutes when flights run late. Over the most recent 24 months of BTS data, 2,731 flights were recorded on this pairing — 110 cancelled (4.0%) and 23 diverted (0.8%). Those baseline metrics tell you what to expect before you book.

Having 11 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,260 total flights analyzed, the 76.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 85.9-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, Feb 2024 posted the best performance on this corridor at 85% on-time, while Feb 2025 came in at 46% on-time — a 40-point gap between best and worst recent month. For travelers evaluating the HSV to DCA route, the combination of a 76.9% on-time rate, 85.9-minute average delay, 4.0% recent cancellation rate, and 11 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
