The CKYH Alliance (COSCON, KLine, Yang Ming, and Hanjin Shipping) will restructure five of their current Asia-U.S. East Coast loops as of May 2012. AWE-6 is scheduled to resume from middle of May 2012 replacing AWE-5 which was suspended during winter season. The Alliance partners believe these changes will enhance service network between Asia to U.S. East Coast while offering customers competitive sailing frequency, transit time and service coverage so as to fulfill their needs.
