I'm only just starting to look into the Asiana program, but one ways...? Under the notes section of
this page it says:
"You can not use a reward ticket to make a one-way trip. Only round trips are permitted."
Am I missing something...?
Oh, here's what I missed... From
this page:
One Way redemptions are permitted at 50% of the roundtrip pricing.
Asiana redemption system is tricky in this respect, as you have just found out.
Simply put, flying Asiana with mileage, you can do one-way at half the cost. Flying Star Alliance partners, no one-way for you.
