If you are looking for delays for a current flight that has not taken off, then you would just compare the filed_departuretime against current time.

Hello @cbw

Our customer calculates delay like given below:

If flight has scheduled at 3:00PM and If its departure will be late than given time, Its considered as late. How can we tell them that a flight is delay based on your answer?

Above link do not reveal departure-delay information when flight is not departured. Here is API’s result of flightInfoEx:

{
"FlightInfoExResult":{
"next_offset":1,
"flights":[
{
"faFlightID":"AAL72-1621468680-schedule-0688",
"ident":"AAL72",
"aircrafttype":"B789",
"filed_ete":"13:30:00",
"filed_time":1621468680,
"filed_departuretime":1621641300,
"filed_airspeed_kts":472,
"filed_airspeed_mach":"",
"filed_altitude":0,
"route":"",
"actualdeparturetime":0,
"estimatedarrivaltime":1621690500,

"destination":"KLAX",
"originName":"Sydney",
"originCity":"Sydney, NSW",
"destinationName":"Los Angeles Intl",

}
]
}
}
