just a quick question: i am looking to book NRT-ICN-NRT for June next year... Any experience when the booking will open? The farthest that I can see is March 2015.

Sorry, am a bit inexperienced with Asiana booking (though I flew OZ a few times)

PS: I can book it via ANA (OZ codeshare since they don't fly NRT ICN anymore), but normally it's much more expensive and from my experience, earns smaller number of miles
