Delta Air Lines and United Airlines have asked to resume flights to China this month, even as Chinese carriers have continued US flights during the pandemic.
Trump’s administration on 22nd May accused the Chinese government of making it impossible for US airlines to resume service to China, they then ordered four Chinese carriers to file flight schedules with the US government.
China's "Five One" Flight Policy
China's government launched its "Five One" policy at the end of March, in a bid to curb the COVID-19 crisis; allowing one airline to serve one country from one Chinese city to one foreign city, with no more than one flight a week.
However, many foreign airlines are anxious to see more international routes allowed into China. The "Five One" policy has caused a shortage in terms of capacity and travellers flying to China from overseas are facing very steep airfares, in the current COVID-19 climate.
