AUS to BNA questions

What time of day is best to fly AUS to BNA?
Before 9 AM: 91% of flights arrived on time, against 63% for departures after 9 PM. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
Which airline is most on time from AUS to BNA?
Southwest, with a season-adjusted 77% chance of operating and arriving on time over 2,017 flights. The adjustment compares each airline with what the route did in the months it flew, so a carrier that skipped a stormy month gets no free credit.
What is the worst month for delays on AUS to BNA?
May (69% on time); the best was February (86%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
