- Allegiant, with a season-adjusted 75% chance of operating and arriving on time over 517 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.

- July (70% on time); the best was April (86%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
