Dayton to Atlanta

What the Data Says About DAY to ATL

The Dayton to Atlanta corridor (DAY → ATL) covers roughly 432 miles and is served by 6 carriers, based on Bureau of Transportation Statistics reporting. Across 7,551 flights in the dataset, this route posts a 91.9% on-time rate with an average delay of 95.5 minutes when flights run late. Over the most recent 24 months of BTS data, 2,725 flights were recorded on this pairing — 28 cancelled (1.0%) and 3 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 6 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 7,551 total flights analyzed, the 91.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 95.5-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 100% on-time, while Jan 2025 came in at 79% on-time — a 21-point gap between best and worst recent month. For travelers evaluating the DAY to ATL route, the combination of a 91.9% on-time rate, 95.5-minute average delay, 1.0% recent cancellation rate, and 6 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
