Historical odds, not a guarantee. Built from the US DOT Bureau of Transportation Statistics on-time reports (Jun 2025 to May 2026), FAA ground stop and delay program advisories, and 20 years of airport weather observations. Covers US airlines that report to the DOT; schedules are flights operated recently, so confirm times when you book. ATIS Alerts is not affiliated with any airline.

Finding the most reliable connections from ILM to LGA…

ILM to LGA questions

What time of day is best to fly ILM to LGA?
Before 9 AM: 90% of flights arrived on time, against 61% for departures noon to 3 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 ILM to LGA?
Republic, with a season-adjusted 72% chance of operating and arriving on time over 1,019 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.
What is the worst month for delays on ILM to LGA?
July (76% on time); the best was September (89%), averaged over Jun 2023 to May 2026.
Is this a prediction for my flight?
No. These are historical odds from the US DOT on-time reports, FAA advisories and airport weather records. Check your flight status and the FAA delay board on the day you fly.
