Atlanta to Austin

What the Data Says About ATL to AUS

The Atlanta to Austin corridor (ATL → AUS) covers roughly 813 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 22,572 flights in the dataset, this route posts a 80.4% on-time rate with an average delay of 57.5 minutes when flights run late. Over the most recent 24 months of BTS data, 8,830 flights were recorded on this pairing — 84 cancelled (1.0%) and 14 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 15 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 22,572 total flights analyzed, the 80.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 57.5-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 89% on-time, while May 2024 came in at 57% on-time — a 32-point gap between best and worst recent month. For travelers evaluating the ATL to AUS route, the combination of a 80.4% on-time rate, 57.5-minute average delay, 1.0% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
