It will be my first time going to South America, and first time on LAN.

I am here to ask for help. Trying to book award tickets from LPB to IPC and then from IPC to PPT in early/ mid April 2016. I can't find anything on BA.com. I don't have any LANPASS miles yet, but am planning to get some SPG sign up bonus to transfer to LANPASS. I have plenty of AAdvantage/ Alaska/ UA miles but don't think they are useful.

The worst case scenario is to use TY/ UR points, but IPC to PPT is going to be over $1k per ticket...

Any tips would be appreciated. Thank you!
