Header filters filter all the data of a dashboard: it only shows the flights that match the characteristics you choose.
How do I use them?
Predefined filters sit at the top of the dashboard, for example Airport and Airline.
Click Show more to see the full list of predefined filters (for example scheduled date and time, flight number, aircraft model, or delay code).
Click Add filter for more specific ones. You can search them by name.
The time filter
Every filter accepts flexible conditions, especially the time filter. You can choose:
In the past: a period counting back from today, for example the last 30 days.
Between: a fixed range between two dates, for example 01 Sep to 30 Sep.
More: add conditions to make the filter more flexible.
Compare to: the period you compare against, for example the previous period.
For the steps, see How do I change the date range in Analytics?
