Agreed, QR would likely use VA as weapon to bully QF out of OW before eventually admitting VA into OW, even with just a 20% stake. Since QR is 100% owned by an autocratic state with unlimited oil wealth, they can deploy whatever it takes to bully our national carrier out of the alliance and solidify its oryxworld agenda. Would certainly be odd as Virgin Atlantic is a SkyTeam member while Virgin Australia would be a member of oneworld.
Although QF has veto powers in OW. And QF leaving OW would be a significant blow to QF’s commercial image (since they’re a founding member whereas QR only barged in in 2013), and hence harmful to Australia’s image in the global economy as well. I know Qantas deeply regrets not vetoing QR’s application for OW in 2012 because they were a very small boutique airline at the time that didn’t even fly to Australia, but they’re making the same mistake even now with staying silent on QR’s sidekick Oman Air’s application.
