Atlanta to Dallas

What the Data Says About ATL to DAL

The Atlanta to Dallas corridor (ATL → DAL) covers roughly 721 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 19,678 flights in the dataset, this route posts a 82.5% on-time rate with an average delay of 62.0 minutes when flights run late. Over the most recent 24 months of BTS data, 7,021 flights were recorded on this pairing — 76 cancelled (1.1%) and 30 diverted (0.4%). 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 19,678 total flights analyzed, the 82.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 62.0-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 91% on-time, while Jun 2025 came in at 66% on-time — a 24-point gap between best and worst recent month. For travelers evaluating the ATL to DAL route, the combination of a 82.5% on-time rate, 62.0-minute average delay, 1.1% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
