- Which airline is most on time from TRI to ATL?
- Delta, with a season-adjusted 83% chance of operating and arriving on time over 391 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.

- January (76% on time); the best was April (97%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
