Cargo flights are presumably still permitted.

The cabin crew unions have been complaining, because crew on layovers in SIN have been told to stay in their hotel rooms the entire time they are there.

The same unions have also demanded, and KLM has agreed, that all dead-heading crew must travel in in WBC, even if that means off-loading pax. This is in order to comply with social distancing rules, which rules apparently do not apply to pax traveling in coach. Or else the unions couldn't care less.
