I'll let you know. Part of the difficulty with this routing, as I'm sure you guessed, is figuring out how to include IPC on an itinerary that starts in SCL. This was the best I could come up with. But I'll let you all know once it's ticketed (presumably in a couple of weeks). My current biggest problem is that my EZE-MIA flight is on LAN Argentina (holding two seats in D). The AA EZE-MIA and AA EZE-JFK flights have no A or D availability yet. And, because this is my first international flight, I can't make ANY changes (even to carrier) once I ticket this should D on the AA flights open up later closer to departure (and after June) (at least, that's how it was explained to me). This is a real pain, because it will mean I won't make Platinum (via a challenge) until way into my trip (my only other AA legs are MIA-EZE-DFW-OGG//HNL-NRT (codeshare)).

On Iguazu over Niagra, we will ultimately visit both Iguazu and Victoria Falls on this trip, so Niagra would complete the trifecta.
