South African Airways has made this announcement:
South African Airways (SAA) has taken note of a decision by the South African Civil Aviation Authority (SACAA) to indefinitely ground all Comair flights in South Africa.
As a result, demand for seats across all domestic airlines has been extremely high given that 40% of normal seat capacity has been removed from the market.
SAA has not increased fares because of Comair’s temporary grounding. The airline has deployed bigger aircraft on some Durban and Cape Town flights and will continue to do so until the current situation stabilizes.
