I can't find any press releases or anything like that, but according to the schedules (at least on Travelocity) it would appear that KE is no longer taking on passengers in ANC in the off-season. I found a three-times weekly seasonal nonstop between ANC-ICN on a KE A330-300 (Sunday, Wednesday, Friday) operating late June through August, but no nonstop flights for the rest of the year. Searched through November.
Anyone know anything about this? It'd be a shame if KE is no longer taking on winter pax in ANC. However, CI still has the ANC-TPE flight year-round, and I would imagine that passenger numbers between Anchorage and Asia dwindle quite a bit in the winter, to the point where it would be difficult for two airlines to compete in the ANC-Asia market in the offseason.
