The cancellations follow an announcement by the South African Cabin Crew Association (SACCA) and the National Union of Metalworkers of South Africa (NUMSA) that their members will embark on strike from Friday morning, the airline said.
They’re unhappy with SAA’s restructuring plans which it announced this week in a bid to keep it afloat.
The airline said that more than 900 jobs could be lost in the process.
The flight cancellations were meant to minimise the impact of disruptions for its customers,’’ the airline said in a statement.
Flights operated by South African Airways partner airlines SA Express, Mango, SA Airlink will not be affected, according to the airline.
During labour negotiations with unions, South African Airways had offered employees a 5.9 per cent salary increase, subject to the availability of funds from lenders, while employees demand an eight per cent increase, SAA spokesman, Tlali Tlali, said.
SAA has long faced financial difficulties.
In June, its board of directors announced the national carrier needs an additional four billion Rand ($268 million) in immediate funds to survive the current financial year.
