Planning air travel between Paraguay and Colombia

I am traveling to Paraguay and Colombia this October (order and exact dates are still flexible at this time).
Being a resident of the United States, I am accostomed to US-centric travel (i.e., flying to/from the US). However, I have very little experience planning travel that is 100% outside the US.
What resources can I use to compare and book flights between Colombia (most likely Bogotá or Medellin) and Paraguay (Asunción)?
Best Answer
My favorite site for starting to compare flights, all flights, is still hipmunk.com.
Air travel within Latin America is, sadly, overpriced and underserviced. You're not likely to find a good deal on a flight to Paraguay, from anywhere, which is not a popular destination on the continent.
I'm not sure what the current visa situation is for Americans flying to Brazil, but if it's acceptable, you could consider including Foz de Iguacu in your searches.
