Argentine government controls on the US$ exchange rate keeping it at an artificially low 4.60 pesos to 1 US$ has made travel to Argentina more expensive for Brazilians resulting in only 40 or so charter flights by GOL and TAM from Brazil to the Argentine ski resort of Bariloche, far fewer than the 140 flights originally planned. The slowing Brazilian economy and weaker Real are surely factors too.
Also, Aerolineas Argentinas has fewer flights from Sao Paulo to Bariloche plus Las Lenas, San Martin de los Andes and Ushuaia are also receiving fewer charter flights than expected this winter season.
Restrictions imposed by the Argentine government on purchases of US$ by Argentine citizens have also seen a reduced number of outbound charters.
