There were 10 cancellations of domestic flights and delays of international flights, a Sydney Airport spokesperson told Reuters at 8 a.m. local time (2200 GMT on Friday). While the fog had lifted by noon, delays of up to an hour for international and domestic flights continued, the airport spokesman said.
