From your FAQ, you suggest the calculation of arrival delay of a flight using the following formula:
How late the arrival was = (actualarrivaltime - (filed_departuretime + filed_ete)).
I’m using that formula on FlightInfoStatus, the problem is that the results seems inaccurate!
Do you suggest to use the arrival_delay value instead to obtain the desired result?
Consulting that value, seems for correct than the computed one.
