Washington to Savannah

What the Data Says About DCA to SAV

The Washington to Savannah corridor (DCA → SAV) covers roughly 519 miles and is served by 11 carriers, based on Bureau of Transportation Statistics reporting. Across 4,267 flights in the dataset, this route posts a 75.9% on-time rate with an average delay of 77.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,965 flights were recorded on this pairing — 72 cancelled (3.7%) and 7 diverted (0.4%). 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 4,267 total flights analyzed, the 75.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 77.6-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 Jul 2025 came in at 56% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the DCA to SAV route, the combination of a 75.9% on-time rate, 77.6-minute average delay, 3.7% recent cancellation rate, and 11 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
