Will your flight be late?
Tell us the flight. Pick the day you’re flying and we’ll give you the odds; they get sharper as the weather forecast, the FAA and your plane’s earlier flights come into focus.
Typical odds Too early for a weather forecast — these are typical odds for departures at these airports on a Sunday in October, from the weather this date has had in past years. They’ll switch to forecast-based odds about 3 days before departure.
Schedule: a typical Sunday (the flights of Jul 26, 2026, re-dated). Real flights replace these once the FAA publishes them, usually about a day ahead.

“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: a typical Sunday (the flights of Jul 26, 2026, re-dated). Real flights replace these once the FAA publishes them, usually about a day ahead.
