Award availability on Asiana

Anyone had any luck booking awards flight with Star Alliance partners on OZ?

This is a supposedly generous plan, only 80K miles for first class MSP-ORD-NRT-SHE flying UA and ANA. But I'm, having the devils own time getting anything to show up.

Tried booking an international mileage ticket on and they only show a handful of US cities for departures, and only South Korean airports for arrivals. I looked at ORD-ICN in all classes, and nothing showed up.
