A major computer failure at OR Tambo International airport on Thursday morning led to some delays.
Airports Company South Africa (Acsa) spokesperson Solomon Makgale told the Mail & Guardian Online that some flights ”on one or two airlines” had been delayed because passengers had to be checked in manually.
He could not yet confirm which airlines had been affected, but said South African Airways flights went ahead as scheduled.
Earlier on Thursday, Makgale had advised travellers to get to the airport earlier than usual to avoid further delays, but by 8am, he said, queues in the terminal were back to normal.
Acsa could not yet confirm the cause of the computer failure.
