- Which airline is most on time from JFK to FLL?
- Delta, with a season-adjusted 73% chance of operating and arriving on time over 1,614 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 (64% on time); the best was November (84%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
