Austin to Nashville

What the Data Says About AUS to BNA

The Austin to Nashville corridor (AUS → BNA) covers roughly 756 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 13,841 flights in the dataset, this route posts a 81.4% on-time rate with an average delay of 63.4 minutes when flights run late. Over the most recent 24 months of BTS data, 6,082 flights were recorded on this pairing — 36 cancelled (0.6%) and 12 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 16 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 13,841 total flights analyzed, the 81.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.4-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, Jan 2025 posted the best performance on this corridor at 90% on-time, while May 2024 came in at 64% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the AUS to BNA route, the combination of a 81.4% on-time rate, 63.4-minute average delay, 0.6% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
