WHY DELAYODDS

About DelayOdds

Why we built an independent, route-level view of historical U.S. flight reliability.

Why this exists

“Are evening flights worse?” and “Which airline is more reliable on this route?” are simple questions buried inside a very large public dataset. DelayOdds turns those records into legible route reports without pretending historical statistics know tomorrow's weather.

Editorial principles

  • Show the sample beside the percentage.
  • Keep route direction explicit.
  • Publish the denominator and thresholds.
  • Withhold weak slices instead of manufacturing certainty.
  • Separate planning evidence from live operational advice.

Independent project

DelayOdds is independent. It is not affiliated with BTS, DOT, an airline, or an airport. Questions about a current trip belong with the airline or airport.
