Cancellations by day
6 Jul to 21 SeptThu 17 Sept: 590 cancelled of 56,874 tracked (1.0%) across 219 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.
Airports missing from this count
Some airport boards remove cancelled flights instead of labelling them, so there is no cancellation figure to read at these airports. The busiest of them:
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.
