South African Airways Rebuilding: After five years of anti-apartheid sanctions, South African Airways has returned to the United States, carrying business travelers and tourists. SAA resumed service over the weekend, and business is said to be booming. But so far, no American carrier is ready to offer reciprocal service into South Africa. SAA said that from this Saturday through January, every economy class seat has been taken on the twice-weekly flights. President Bush’s decision this summer to lift the anti-apartheid sanctions let SAA resume the flights. Anti-apartheid activists in the United States aren’t pleased to see SAA return.
