Under the new rules, if five or more passengers test positive for Covid-19 after arriving in China on a flight, the airline company will be banned from running those flights for two weeks, it said.
A four-week suspension will be served if 10 or more passengers test positive for the virus, it said. Airlines will be allowed to resume flying one flight per week on the route once the suspension ends.
Previously, airlines had to serve a one-week suspension if five or more passengers on a flight tested positive for Covid-19. The tightened restrictions are implemented with immediate effect.
On Tuesday, the Civil Aviation Administration of China issued one-week suspension notices to Ethiopian Airlines, the Russian airline Pegas Fly, and Swiss International Air Lines after five or more passengers who traveled on their flights tested positive for Covid-19.
