redeeming asiana flights on asiana website
 

are there any airlines you can redeem on OZ, that doesnt pass on YQ?
didnt manage to check all, but seems like all the ones i see so far do
perhaps, except EY?

also, am i right you need to call up to book any award flights that doesnt go via ICN? because the computer search system appear to only allow international flights that go through ICN
