This is an error fare guys….Latam Airlines have round trip airfares travelling from Miami (MIA) to Asuncion (ASU), Buenos Aires (EZE), Santiago (SCL) and Sao Paulo (GRU) starting from $300. Flights make two stops and pretty long but it’s cheap!!
Travel availability:
September thru early December 2017
Use google flights to search for availability, then book it on Priceline or Orbitz. . Bundling hotel with airfare will save money.
I have two samples attached.
