LGA to ORD questions

What time of day is best to fly LGA to ORD?
Before 9 AM: 85% of flights arrived on time, against 51% 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 ORD?
Delta, with a season-adjusted 65% chance of operating and arriving on time over 2,289 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 LGA to ORD?
October (56% on time); the best was February (80%), from one year of data, so one bad storm season can move a month.
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.
