SAA cans flights to Zimbabwe
South African Airways on Monday night cancelled its Johannesburg to Harare flight after pilots complained that runway lighting at Harare International Airport was poor.
SAA runs two flights to Harare daily. The airline has steadily filled the void left by Air Zimbabwe, which reportedly has "operational problems".
The cancellation was met with an immediate response from the Civil Aviation Authority of Zimbabwe.
"We did not want it to get to this and so we have written to SAA because we want to improve the situation. These lights are adjustable," said CEO of the authority David Chawota.
Chawota said SAA was the only carrier that had complained and withdrawn its service.
The beleaguered Air Zimbabwe faces an international ban on its flights landing abroad if it fails to adhere to international safety requirements by the end of next month.
