“Above normal” (the red part of each bar) is how much worse the late-departure chance is than our estimate for the same flights on a normal day — today that’s the weather forecast; live FAA and airport conditions will join it. Every chart uses the same scale. Airports with too little flight data aren’t shown. Schedule: the flights that flew on Saturday, Oct 10, re-dated. Real flights replace these once airlines file their FAA flight plans, usually about a day ahead.
