i'm trying to book a one-way coach saver award, MIA-EZE. lan arg (4M) shows availability in coach (YS+) on the KVS tool, amadeus-oneworld. but when i call AA to book it, they tell me it's only available in biz. i called 4M who tells me the seats in coach are available to OW members. KVS uses qantas to show availability, so if it's available to qantas, it should be available to AA, right? why can't AA see them? are they blocking them? any clues?
