Ranked by cancelled departures on each airport's own board so far today. Orange marks a cancellation rate at least double what that airport usually runs over the past fortnight.
Cancellations by day
6 Jul to 9 SeptToday so far: 326 cancelled, still counting
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 dashed bar is today, still counting.
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.
How many flights are cancelled today?
We read the departure boards at the airports we monitor and record every departure the airport itself marks as cancelled, counting each scheduled flight once. So far today that is 326 cancelled departures out of 49,057 tracked, a rate of 0.7%, with Istanbul (IST) worst at 25. Most airports sit near 1 to 2% on an ordinary day.
These figures come from the airport boards themselves and cover departures leaving each airport, so they will not match an airline's own global cancellation count or a national aviation figure. Airports whose boards omit cancellation status are listed above.
If your own flight is already showing a delay, the cancellation risk calculator covers what usually happens next: across 90 days of resolved flights, a posted delay of 70 minutes or more ends in cancellation about 1.9% of the time.
