Ranked by cancelled departures on each airport's own board that day. Orange marks a cancellation rate at least double what that airport usually runs over the past fortnight.

Thu 6 Aug: 955 cancelled of 58,858 tracked (1.6%) across 222 airports

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.

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.
