LAN LANPASS - LAN South American routing with OW redemptions in mind. Help!

Hi,

Sorry if this has been asked before. And it is quite lengthy. I posted in BAEC section, but they suggested posting here as well.

I didn't get in on the bargain deals in BAEC prior to the changeover to Avios on Nov 15 because I cannot plan my vacation that far ahead. I'm still looking at booking in 5 months but planning it now.

I am having trouble with routing. Here are some proposed ideas below. Help appreciated with suggestions next to the routing:

Wife and I have 230k-ish (I think) miles to burn on this trip and it will be our last with Avios. If I could have booked this thing before Nov 15th trust me I would have.

I am currently looking at doing this:

MIA-GYE
GYE-GPS-GYE (does NOT show up in BAEC online booking)
GYE-EZE (does direct routing exist?)
EZE-SCL
SCL-IPC (again, it routes through LIM!? There is a direct flight correct?)
(possibly IPC-PPT-IPC but CANNOT find availability for this AT ALL)
IPC-LIM (again, cannot find on BAEC)
(possibly LIM-CUZ-LIM again based on timing)
LIM-MIA

Instead, i'm being forced to do:

MIA-GYE
GYE-GPS-GYE
GYE-LIM (Any ideas on making this a smoother journey that it is already?)
(LIM-CUZ-LIM)
LIM-IPC
IPC-SCL
SCL-EZE
EZE-LIM (Anywhere to go but back to LIM to get to MIA??)
LIM-MIA

After looking at this, I am warming to the second itinerary.

Any suggestions of how to get back to MIA instead of going EZE-LIM-MIA? Where could I route the EZE-MIA flight and not backtrack?

If I could figure that out I'd be happiest, definitely, but having a hard time finding a way back with EZE that doesn't hit up where I've been already.

Also any info on the IPC and PPT flights would be wonderful.

Thanks!

You can just take the daily 4M flight nonstop back to MIA

Hmm, I can only find routing through SCL....this may be another glitch in the system?
