I am planning a trip in November to Chile and Argentina. I am having some difficulty booking the Santiago, Chile to Bariloche, Argentina. This appears to be because the flight to Bariloche is to a different airport (AEP) than the arrival from Chile (EZE). Is there a way to do this? Additionally once I could not do the above itinerary I was trying to book the AEP to BRC part of the trip from 11/22 to 11/27 and the BA website shows no availability. Is there a way to find out if there are no award seats left or if there is just a problem with BA seeing the LAN availability? Several threads here seem to indicate that BA and LAN reservation systems don't like each other. When I called BA, the agent seemed to indicate that even availability online was not accurate. I haven't finished the booking for different dates bc I really wanted the 22nd to the 27th dates. Any thoughts are appreciated.
