Beleaguered national airline South African Airways (SAA) announced on Tuesday it was cancelling 10 domestic and one international flight in an effort to streamline services and save cash.

The cash-strapped airline was last month placed under a state-approved business rescue plan to avoid its total collapse following a costly week-long strike by thousands of its workers.

SAA said in was dropping 10 domestic flights between Johannesburg, Cape Town and Durban, while canning its direct route between Johannesburg and Munich.

Passengers on cancelled domestic flights will be accommodated on its budget sister airline, Mango, while international travelers would be re-routed via its flights between Johannesburg and Frankfurt, and London Heathrow.

"These decisions are in line with SAA's usual policy of reviewing flights and consolidating services with low demand," it said in a statement.

"Furthermore, during the current process of business rescue, these cancellations represent a responsible strategy to conserve cash and optimise the airline's position ahead of any further capital investment."
