Hello and thanks in advance for helping,
I need to map the fleet of specific operators. To minimize requesting info from the same aircraft multiple times, I 'm using the tailnumber as unique identifier. Nevertheless, this field has a high percent of chance to not be available when using FlightXML2 FleetArrived/FleetScheduled or FlightXML3 FleetBoards. In the other hand, the faFlightID field is always available but I don’t know if the same aircraft may have multiples faFlightID. Moreover, is there a better field to look for to map each aircraft from given operator?
