Comair
Comair, which runs Kulula and British Airways flights in South Africa, has grounded its flights with immediate effect because of a funding crisis - its also suspended ticket sales.
Comair is tweeting on its official twitter handle that it regrets to advise that its flights have been voluntarily suspended from today (Wednesday 1 June) pending securing funding to resume operations.
Comair's message to travellers is that if their flight has been cancelled, they must not make their way to the airport unless they have made alternative arrangements.
"Our heartfelt apologies for the inconvenience," tweeted Comair without giving any indication as to when operations might resume
