US airlines say China has blocked more than a dozen recent and future flights from entering the country, which has been tightening already-strict COVID-19 travel restrictions.
China ordered the cancellations after some passengers tested positive for COVID-19 on flights that arrived in China in late December, according to industry officials.
American Airlines said Tuesday that six of its flights from Dallas-Fort Worth to Shanghai in late January and early February have been cancelled.
United Airlines said it was forced to cancel six flights from San Francisco to Shanghai later this month. Delta Air Lines said it cancelled one flight last week and another this Friday to Shanghai.
Airlines for America, which represents the largest US passenger and cargo carriers, said it was discussing the matter with US and Chinese government officials to find ways to minimise the impact on travellers.
The Biden administration had no immediate comment.
The blocking of flights is the latest development in a dispute between the two countries over international flights and rules designed to prevent the spread of the coronavirus.
China has been ratcheting up travel restrictions after recent outbreaks of COVID-19 as it prepares to host the Winter Olympics in early February. China limits capacity on inbound flights currently to 75 per cent and requires passengers to be tested before departure and after arriving in the country.
If passengers test positive, the airline that carried them can be forced to cancel two to four flights, depending on the number of positive cases.
Last month, Delta said new requirements for cleaning planes between flights caused a plane bound for Shanghai to return to Seattle. The airline said the new rules extended the time planes would need to sit on the ground in Shanghai, and weren’t workable. The Chinese consulate in San Francisco lodged a protest over Delta’s decision.
In 2020, the Trump administration backed down from a threat to block four Chinese airlines after China agreed to let United and Delta resume limited operations that were shuttered earlier in the pandemic.
Last August, the US Transportation Department limited the number of passengers on four Chinese airlines’ flights to the US after China imposed similar limits on United Airlines. The US said China was putting an unreasonable burden on US airlines for travellers who test positive after arriving in China.
