I haven't noticed a thread on this topic. If all flights to/from China are cancelled for a significant period of time (as well as flights to HKG reduced), are all those planes and crews idled, or will they be redirected onto routes that could use some more capacity?

MOD EDIT: please use THIS thread to discuss widebodies showing up on unexpected UA routes.
