SAA has temporarily suspended flights between Johannesburg and Abuja, effective since May 25.
SAA spokesperson Tlali Tlali said the suspension of services was due to unspecified operational reasons.
He could not confirm when flights would resume.
Uzair Desai, GM of Corporate Traveller, said that passengers could be re-accommodated on flights to Lagos, fly to Abuja via Addis Ababa, or even cancel their flights and request a refund.
