Air Traffic and Navigation Services ATNS says flight delays and diversions are expected at three of South Africas international airports, as it undertakes maintenance on key flight procedures.
These include Chief Dawid Stuurman International Airport in Gqeberha, Polokwane International Airport in Limpopo, and Kruger Mpumalanga International Airport.
ATNS spokesperson Mphilo Dlamini says the delays form part of a safety compliance programme approved by the Civil Aviation Authority CAA.
