Friday's strike by 3800 staff is part of an ongoing campaign of protected industrial action by baggage handlers and ground staff over pay and conditions.
The one hour stoppage was called to update members on negotiations with Qantas and recommend further action, the TWU said in a statement, accusing airline management of "a deliberate war of attrition".
But Qantas said the TWU was holding passengers to ransom and trying to maximise disruption and argues its claim for a 15 per cent pay increase over the next three years is unsustainable.
Qantas spokeswoman Oliva Wirth said Qantas engineers will also strike for one hour in Sydney on Tuesday afternoon and in Melbourne on Friday, causing expected delays for "several thousand" passengers.
Meanwhile, international air travellers will face delays at Australian airports this week and next as customs officers take industrial action amid a standoff over pay and conditions.
The protected action this week will affect passengers at international terminals on Tuesday at Sydney, Melbourne, Brisbane, Perth, Adelaide and Cairns.
Sydney's international airport will also be affected on Thursday and Saturday, along with Cairns airport.
The action comes after a stalemate in negotiations on a new enterprise agreement with Australian Customs and Border Protection. The previous agreement expired at the end of June.
