I watched an Air China 744 fly over San Diego that was operating CCA27 Montego Bay-Honolulu. Any one know why?, airchina.com didn’t seem to know.

Air China operates flights for government officials. Looking at the other flight listed for CCA27 (flightaware.com/live/flight/CCA2 … /LICJ/MROC), I would say this is a government flight.
Do some research to see if you can find any governmental meetings involving the Chinese government around these dates.
