The Australian Competition and Consumer Commission (ACCC) has begun proceedings against Japan Airlines (JAL) and Air New Zealand (ANZ) for alleged price fixing in the air cargo industry.
The two carriers bring the total number of airlines investigated by the ACCC to 15.
JAL and ANZ allegedly entered into arrangements with other international air cargo carriers "that had the purpose or effect of fixing the price of a fuel surcharge and a security surcharge that were applied to air cargo carried by them and other airlines", says the ACCC.
"The ACCC alleges that arrangements or understandings were reached in Singapore, Hong Kong and Japan for fuel surcharges applied to cargo originating in those countries," it adds.
JAL and ANZ had also allegedly concluded similar arrangements for a security surcharge applied to cargo originating in Singapore and Hong Kong, says the ACCC.
A hearing has been set for 10 June in Sydney's Federal Court, it adds.
The ACCC had previously begun proceedings against Singapore Airlines Cargo, Cathay Pacific Airways, Emirates, Garuda Indonesia, Thai Airways International, Korean Air, Malaysian Airlines and its cargo subsidiary MASkargo.
In previous cases, six airlines were ordered to pay A$41 million ($36 million) in penalties after they were taken to court by the ACCC.
