The Commercial Aviation Association of South Africa (CAASA) has requested Airports Company South Africa (ACSA) to keep Durban International Airport in operation after it announced its intentions to close it.

ACSA said it wants to close the airport and sell the land, citing competition concerns after the new King Shaka Airport at La Mercy opens in 2010.

CAASA also said a complaint would be lodged against ACSA with The Competition Commission if it makes no efforts keep the airport in operation.

Last month, ACSA rejected a purchase offer for the airport by Comair, an airline group.
