Goes to show what!???
Rather go read the thread about world cup flights, surely all those extra flights and larger aircraft isn't just for people leaving the country, but infact the others coming in. How many people should really use Cathay Pacific to the World Cup...the Chinese...maybe the North Korean teams followers...? The Japanese followers might be using it, as they've got quite a large following contingent already...but they much more prefer SQ, MH and SA (with ANA codeshare).
Some airlines are flying specially for the world cup to SA, like Aerolinas Argentinas, TAM, LANChile, Gol, AeroMexico and several charter companies from Europe, while many of the usual carriers is adding flights and also using larger aircraft. Infact just last week AR increased the amount of flights for the tournament from 14 to 22 (all 747-400).
Ofcourse there is people also going out of the country, normal business practices around the world and in SA carries on, while also school holidays, so people take advantage of it to take annual leave, that's just beneficial for the airlines.
On pprune there is always more people that want to be pessimistic and just look for the bad things...just goes to show...
