BNA to SLC questions
- What time of day is best to fly BNA to SLC?
- Before 9 AM: 90% of flights arrived on time, against 78% for departures 9 AM to noon. Later flights inherit delays from earlier ones, so the first departures of the day usually run best.
- Which airline is most on time from BNA to SLC?
- Delta, with a season-adjusted 86% chance of operating and arriving on time over 934 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.

- June (77% on time); the best was November (91%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
