Washington to Atlanta

What the Data Says About DCA to ATL

The Washington to Atlanta corridor (DCA → ATL) covers roughly 547 miles and is served by 41 carriers, based on Bureau of Transportation Statistics reporting. Across 35,728 flights in the dataset, this route posts a 83.9% on-time rate with an average delay of 79.5 minutes when flights run late. Over the most recent 24 months of BTS data, 13,741 flights were recorded on this pairing — 302 cancelled (2.2%) and 27 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 41 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 35,728 total flights analyzed, the 83.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.5-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 Jul 2024 came in at 67% on-time — a 25-point gap between best and worst recent month. For travelers evaluating the DCA to ATL route, the combination of a 83.9% on-time rate, 79.5-minute average delay, 2.2% recent cancellation rate, and 41 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
