About PPT - I know that it is SWP, but why I can't have flight SCL-PPT-SCL (LA 833/834)?
About dates - Is it apply minimum stay rule (10 days for all classes)?</font>
You can't go back to SCL after traveling to PPT because you would then be making two transitions between IATA Area 1 (Americas) and IATA Area 3(Asia/SWP). Only one is allowed. I suggest you give up on PPT anyway. It is tremendously overpriced. You will find DPS a much nicer place to spend some time in the sun if that is what you are looking for.
The 10 day minimum stay rule is for the entire trip, not each region. It looks like your dates are fine.
