Dallas to Atlanta

What the Data Says About DAL to ATL

The Dallas to Atlanta corridor (DAL → ATL) covers roughly 721 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 19,618 flights in the dataset, this route posts a 82% on-time rate with an average delay of 75.2 minutes when flights run late. Over the most recent 24 months of BTS data, 7,040 flights were recorded on this pairing — 91 cancelled (1.3%) and 18 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 19,618 total flights analyzed, the 82% on-time figure is statistically meaningful rather than a small-sample fluke. The 75.2-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 88% on-time, while Jun 2025 came in at 67% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the DAL to ATL route, the combination of a 82% on-time rate, 75.2-minute average delay, 1.3% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
