Washington to Huntsville

What the Data Says About DCA to HSV

The Washington to Huntsville corridor (DCA → HSV) covers roughly 613 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 6,263 flights in the dataset, this route posts a 78.6% on-time rate with an average delay of 73.1 minutes when flights run late. Over the most recent 24 months of BTS data, 2,731 flights were recorded on this pairing — 112 cancelled (4.1%) and 5 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 6,263 total flights analyzed, the 78.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 73.1-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 2024 posted the best performance on this corridor at 92% on-time, while Feb 2025 came in at 52% on-time — a 40-point gap between best and worst recent month. For travelers evaluating the DCA to HSV route, the combination of a 78.6% on-time rate, 73.1-minute average delay, 4.1% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
