Fuel Levy

Dear SAA,<br> <br> Presently the fuel prices have come down more than 70% from its peak. Why do you still keep charging the fuel levy? In fact the prices of oil are now lower than when the transportation industry instituted the fuel levy. This has become a source of silent income to you and the flying public is being gouged royally! Additionally you charge a higher fuel levy to fly business class than economy for the same route. Does a business class flyer consume more fuel? What is your justification for continuing to charge this outdated levy and the differential structure between different classes?<br> <br> Your response would be appreciated
