As of 1 May 2010 there is a new King Shaka International airport in Durban. Some flights can be booked directly to Durban instead of going via Johannesburg O.R. Tambo International. This is helpful for visitors flying from an overseas country and also useful for Kwasizabantu Mission transport (since it is about 30 minutes closer for the average vehicle).
