How to get the flight status from API?

Hello, I have investigated many end points like FlightInfoEx , AirlineFlightInfo and SearchBirdseyeInFlight

But I couldn’t find a clear call to get the flight status (i.e. delayed, cancelled, onAir) and specially delayed status.

in SearchBirdseyeInFlight, I know I can set the query to query only the onAir, Cancelled flights but it will require me to make multiple calls to know the status. Also there is no clue to get the “delayed” status

There’s no text based status in the listed endpoints that mirrors the website values. However, Most status values can be calculated from the times presented.

Several common calculations are listed here.
