Not sure whether it was wise for the US3 to start playing political games by dragging in not just 3 airlines but two ultra-wealthy governments (UAE and Qatar) as well, who have much, much bigger lobbying budgets and actual geopolitical leverage than 3 mere public corporations and a US labor union
I mean, if your airline is being targeted by a PR campaigning alleging subsidies and government collusion anyway, why bother holding back in showing what it would look like if those accusations really were true!
