Which airline is most on time from ORD to ELP?
Republic, with a season-adjusted 80% chance of operating and arriving on time over 126 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.

Is this a prediction for my flight?
