Dont understand the issue.
South Africa's economy is booming with some of the richest people in the country now black, and massive businesses now in the hands of black people.
To my simple mind all they have to do is launch a few wholly black owned airlines, employ all and only black crews and personnel, and set and maintain only the highest standards of service and efficiency (and price of course) and shut down those intransigent ones like Comair through fair competition and exceptional service levels.
After all South Africa has its national airline as a shining example of what its black population and business people are capable of, they can surely do that also with any similar private venture.
My humble advice is to stop bickering and get on with the job!
