I have searched, and verified what appears to be the equivalent of "saver" space on a couple of :AN Argentina flights (AEP-IGR-AEP). Availability appears to exist. But when I attempt to book as part of an award redemption using AA miles, the agents tell me there is no availability. (1) this may mean that what seems to be availability on Lan.com is not coextensive with what is available for AA award redemptions. (2) this may mean that the AAgents I have spoken with do not know what they are doing. And, yes, I have hung up and called again. Any thoughts from the assembled?
