Delta and United are looking to restart flights to China. The SARS-CoV-2 virus is largely under control there. It is home to several important business markets.

(For American, despite owning a stake in China Southern, the country has mostly been a place to light cash on fire.)
However they’re caught up in escalating tensions between the U.S. and China and the President’s re-election strategy.
