I was checking the SAS timetable and flightindex this morning and found that all the flights southward and westward were odd: example: SK-501 CPH-LHR and that all flights northward and eastward were even flight numbers example: SK-734 CPH-SVO and SK 735 SVO-CPH, this kind of system is maybe valid for other airlines too.
Has anyone ever thought about this before?
Another example is LOT: all outbound flights from Poland have odd flight numbers, example: LO 631 WAW-SOF, and all returning flights to Poland have even flight numbers, example: LO 632 SOF-WAW.
Can anyone give me an approach why the airlines have systems like this?
