Norwflyer: It is quite usual for airlines not to make available discount class fares (like alliance fares) on routes at times when demand is expected to be very high. I have no inside information, but I imagine that no airline is selling low fares for travel to or from South Africa at around the time of the rugby world cup. Things may change closer to the event, as demand and availability become more clear, but that is not much help if you want to plan ahead. oneworld4u
