The passenger air transportation demand between China and the United States were significantly decreased due to the COVID-19 pandemic starting in late January. The US air carriers (American, Delta, and United) then announced to suspend their flights to China in early February, while Chinese air carriers (Air China, China Eastern, China Southern, Xiamen Airlines) continued to maintain limited passenger services between two countries. In Mid-February, there are only 20 passenger flights, operated by four Chinese air carriers scheduled per week, compared to 325 weekly flight before the pandemic. In March, as the pandemic hit the US and the essential travel demand from the US to China had relatively increased, weekly commercial flights operated by 4 Chinese airlines between two countries increased to 34, plus other private charter flights utilized by Chinese citizens in the US.
