Awards to LIM and SCL on LA metal have decent availability. 4M (LAN Argentina) is unfindable by AA reps for awards - they see the flight but can't see the low level award LAN offers on the site.
I saw BA displaying AEP - BRC for a little but then those disappeared. BA also had some SCL - EZE awards but those too are gone. BA isn't even showing SCL - IPC now.
Quite painful. Anyone else have luck with domestic/intra-South America awards? Longhaul awards in Y and J seem quite open to everywhere but EZE.
Also note that you cannot do one-award on AA Miles to route USA - LIM/BOG - SCL/EZE. Ends up pricing as two awards.
