Each bar is one completed day across every airport board that published cancellations that day. Tap a bar for that day's full ranking. The set of counted airports shifts as boards change behaviour, so read the rate alongside the raw count; a gap means we have no usable record for that day. The outlined bar is the day you are viewing. Showing the most recent 90 days; the full series is in the JSON feed.

A handful of other boards label routine schedule padding as cancelled, and do so to 15 to 27% of departures every day. Those airports are left out too.
