Flight XML3 FlightInfoStatus - How to determine flight has been delayed


I am trying to find whether a flight is delayed or not. Should I use ‘arrival_delay’ or perform diff between actual_arrival_time.epoch and filed_arrival_time.epoch to get the delay time?


After departure and while enroute, you may use the estimatedarrivaltime to compute how far behind the “filed_departuretime + filed_ete” anticipated arrival will be. After arrival, you may compute how far the actualarrivaltime was behind the “filed_departuretime + filed_ete”.
