LGA to CHS questions
- What time of day is best to fly LGA to CHS?
- Before 9 AM: 83% of flights arrived on time, against 64% for departures 6 to 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 LGA to CHS?
- Republic, with a season-adjusted 69% chance of operating and arriving on time over 1,011 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 (69% on time); the best was March (84%), averaged over Jun 2023 to May 2026.
- Is this a prediction for my flight?
