Nashville to Austin

What the Data Says About BNA to AUS

The Nashville to Austin corridor (BNA → AUS) covers roughly 756 miles and is served by 15 carriers, based on Bureau of Transportation Statistics reporting. Across 13,885 flights in the dataset, this route posts a 82.2% on-time rate with an average delay of 61.3 minutes when flights run late. Over the most recent 24 months of BTS data, 6,092 flights were recorded on this pairing — 32 cancelled (0.5%) 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 13,885 total flights analyzed, the 82.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 61.3-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, Nov 2024 posted the best performance on this corridor at 92% on-time, while May 2024 came in at 69% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the BNA to AUS route, the combination of a 82.2% on-time rate, 61.3-minute average delay, 0.5% recent cancellation rate, and 15 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
