Earlier quoted context omitted.
Given that many foreign airlines are at least in part government owned, this could be problematic. Do we really want Air China to come in and drastically undercut US based carriers in order to drive them out of business?
Sure? If the Chinese government (or more realistically Qatar or UAE etc) wants to subsidize US business and tourism by making it cheaper to fly within the US it seems like a good thing for the US. As we've seen, anytime an airline raises prices it is pretty easy for another carrier (or even a brand new carrier) to come in and replace them. So it isn't like a hypothetical foreign government owned carrier could somehow…
1) China comes in and undercuts US prices.
2) US carriers are unable to compete with a business subsidized by one of the largest economies in the world, and China Air forms a monopoly as it drives competitors out of business.
3) China Air folds, leaving the US with no means of air travel at all.
I’m pretty sure China could outlast any airline in the US in a price war, given how thin the margins that US carriers already operate on are. They don’t have to care about making profits—their only goal is to damage the US economy, as on the world stage it’s a zero-sum game. Any damage to the US is a benefit to China.
So yeah, let them. And what effect do you think it will have on the economy when there are literally zero air carriers left in the United States?
