Hi, i always search for Star alliance award tickets at UA site, and found a few available flights (X)economy from Air Canada, Avianca, and Copa airlines ( MIA-GRU, 2/21(Wed) ).
However, when I search directly in Asiana site to purchase it, Air Canada and Copa flights are not showing. I even tried to called Asiana's call center and they said it's not showing for them as well.
Anyone knows why this happens? Thought (X) fare was shared thru all star alliance airlines. Is there any qty blocked to each airline? Or should I wait a few dates for Asiana to update?
