Am i correct to assume (for the reciprocity fee) that your first port of entry into Argentina (at MDZ) is what is relevant, even if that entry point is just a connection? And the final destination (AEP) is not the relevant part.

Answering the following question would most likely help me understand the situation:
So SCL-AEP direct would incur a fee. But SCL-MDZ (no stop)-AEP would not incur a fee,? And SCL-MDZ(stop)-AEP would also not incur a fee?

Appreciate the patience.
