And again not a pissing contest but correcting errors only, ****su Tonka, movements aren't just arrivals. As it says in the notes section of the document you linked, ASA movement figures are calculated by adding Arrivals to Circuits and multiplying by 2, which accounts for departures and other flights. Joburg figures under their notes, while not doing it the same way, quote departures, arrivals, and all other flights, non scheduled, military etc (doesn't matter whether billed or not), and add them all together. End of the day, different counting system but pretty much same outcome.
