Security staff stopped work twice on Friday. Screening stayed open, but lines moved slow.
The first walkout ran from 6 to 10 in the morning. The second ran from 5 to 9 at night.
The walkouts hit domestic and international terminals. Screening ran at reduced capacity.
Hundreds of Certis screeners stopped work. Certis runs security checks at Sydney Airport.
The Transport Workers Union speaks for the screeners. Talks on Thursday did not settle the dispute.
The union wants more full-time jobs. It wants fairer rosters and stable hours.
The union says Certis planned to cut minimum hours by six per week. Certis says it made a fresh offer.
Certis staff also walked off in late September. That round involved a reported 400 staff.
