There is nothing
about it. I have seen screenshots of the emails. Many pilots have been reporting Cabin Crew for going out and about during layovers. Standard responses are interesting. If anyone gets ahold of them that'll be it for closed loop. It'll be full lockdown.
Also red tail flying is Air China operations. Wet lease. Been happening for years but was put on hold for a while. They have been back at it for a while. But that's what close ties with China bring.
