Our interactive dashboard is a source of statistics on causes of delay. We provide this operational flight-by-flight data sent to us from various operators in addition to the data we collect as Network Manager.

Our dashboard gives users access to our analysis tool which aims to provide more detailed information on all delay causes.

Fresh data is made available one week after the end of each calendar month.
