Strike disruption has forced South African Airlines to cancel all of its domestic and regional flights scheduled for Sunday 17 and Monday 18th November, although it will operate all of its scheduled international flights departing from Johannesburg’s Tambo airport on 17 November.

South African Airways has extended cancellation of all of its domestic and regional flights scheduled for 17 and 18 November as a result of ongoing industrial action.

But the carrier says that it intends to restart all of its scheduled international flights from Johannesburg airport on 17 November.

Services departing from South African’s international destinations London, New York, Washington, Munich, Frankfurt and Hong Kong are expected to operate from Monday 18 November. Flights from Sao Paulo will depart for South Africa on 17 November, while the first departure from Perth will not take place until 19 November.

SAA says it has tried to rebook passengers on flights by subsidiary Mango Airlines or partner carrier Airlink. Customers have been warned not to travel to their departure airports “unless in possession of a rebooked itinerary, as SAA will not be able to provide any assistance”, the airline says.

Unions representing cabin crews and maintenance workers launched two-day industrial action on 15 November over pay.

South African notes that it is currently under severe financial pressure, limiting its ability to increase its salary offers. “The strike is going to exacerbate rather than ameliorate our problem, and will result in a set of circumstances from which there may well be no recovery,” states acting chief executive Zuks Ramasia.
