American Airlines and Qantas Airways are making a second attempt at gaining U.S. regulatory permission for a venture that would allow them to coordinate prices and schedules, threatening to cancel services if they are rejected.
The pair's application for a joint venture covering the United States, Australia and New Zealand was rejected in 2016 under the Obama administration amid opposition from rival carriers Hawaiian Airlines and JetBlue Airways.
The airlines have said they hope the new administration will look more favorably on an application as President Donald Trump has promised to boost U.S. industry through lighter regulation and a more hands-off approach to anti-trust enforcement.
"The proposed joint business will significantly improve service, stimulate demand and unlock more than $300 million annually in consumer benefits that are not achievable through any other form of cooperation," Qantas said in a statement on Tuesday.
The statement added that a rejection could result in Qantas reducing the frequency of, downgrading or even canceling its A380 service between Sydney and Dallas/Fort Worth, while American may further reduce services between Los Angeles and Sydney and Auckland.
American Airlines and Qantas currently rely on codeshare agreements to make those routes economically viable. If the venture is approved, the two could offer more flights, including to cities not currently served by either.
Regulators in Australia and New Zealand had approved the first application for the joint venture before it was rejected by the United States.
