SINGAPORE AIRLINES has rerouted its freighter, adding a Nairobi, Kenya stop. The airline’s freighter service, operated on Sundays, now flies Singapore - Johannesburg - Nairobi - Brussels - Johannesburg - Singapore. It’s all to do with yields and available capacity, says cargo sales manager Jean-Pierre Cano. With relatively poor cargo availability out of Johannesburg, and higher yields out of Nairobi, the adjustment made logical sense, he told FTW.
