“To comply with the cleaning requirements at Shanghai Pudong International Airport (PVG) issued by the Chinese government on December 21, Flight 287 from Seattle to Shanghai returned to (Seattle) en route to (Shanghai),,” the spokesperson said in an email to AFP on Monday. .
“The new clean-up measures require significantly extended time on the ground and are not operationally viable for Delta,” he added, without giving details of the measures involved.
According to Chinese media reports, many passengers in the United States ended up with expired COVID tests and expired visas, prompting the Chinese Consulate in San Francisco to formally file a complaint with Delta.
Thousands of flights have been canceled in recent days by airlines around the world, with many pilots and crews falling ill or in quarantine due to the highly contagious Omicron variant of COVID-19.
Many authorities have also tightened restrictions, and Chinese authorities have been particularly on alert with the approach of the Beijing Olympics, which begin in less than 40 days.
