South Africa has suspended the air operator certificate for Comair as a precautionary measure for 24 hours, effectively grounding its fleet and affecting passengers using low-cost airline Kulula as well as British Airways flights, the transport ministry said on Saturday.
Comair has since 1996 serviced local and regional routes from South Africa under the British Airways livery as part of a license agreement.
"The regulator took this decision independently, in line with its mandate to oversee aviation safety," Transport Minister Fikile Mbalula said in a statement.
