China appears to have their coronavirus outbreak largely under control. However they’re now encouraging – even subsidizing – a return of international flights. I’ve worried that they would bring back infected passengers.
Naturally they’ve thought through this problem, and with the current low volume of international flying they are examining each passenger entering the country. Even at the current low volume of international travel to China, though, that’s backing up arriving flights by several hours in some cases. And that can cause unruly passengers.
