Category: Transport

Traffic on a given flight with the same flight number subdivided by airport pairs in accordance with point of embarkation and point of disembarkation on that flight.
For passengers, freight or mail where the airport of embarkation is not known the aircraft origin should be deemed to be the point of embarkation; similarly if the airport of disembarkation is not known the aircraft destination should be deemed to be the point of disembarkation.
