We have an on again/off again relationship with PVG layovers - currently off. The way I read this article they are claiming the virus spread from a canister which wouldn’t necessarily require a crew layover. The union seems to be fighting when conditions get too bad, and with our LOA there is a mechanism to get out of China flying. I think the biggest issue is it is tough to make an informed decision because conditions change so rapidly. The most recent battle appears to be getting Hong Kong layovers either fixed or suspended.
