After a spate of "pilot error" crashes, and the founding of SkyTeam, Delta has sent tens of employees/crew over to Korean Air and China Airlines to institute a CRM program in both airlines. It seems to have worked as neither has had major "pilot error" incident since its inception.
Asiana was seen as a private airline and not a flag carrier like KE. They didn't face the same pressures to hire out of the Air Force like Korean. Asiana could look to United or Lufthansa for guidance on proper CRM.
I find it interesting that the major Chinese airlines haven't had a hull loss since the merger of airlines into Air China, China Southern, and China Eastern.
