To my knowledge, Kulula and 1Time employ staff specifically to prevent such fraud.Obviously the odd one gets away with it, but I know that many are caught-literally hauled off the flight by company security on arrival at their chosen destination.This saves them millions in the long term. The syndicates will try their luck with any carrier.
Clearly SAA doesn't employ the same measures-after all, what's another 14 million to the esteemed National carrier.
Some airlines have to operate in the black-the playing fields are still not level for all........
