There is an Aerochaco webpage with quite a timetable. It includes flights to Iguazu and Salta which are well connected in Resistencia, just an hour or two between. So it seems to be a good way to reach Salta from Iguazu. Web-site says that flights are operated by Macair Jet and tickets are electronically sold through RESIBER, Iberia's booking system. Macair Jet web-site sends you back to www.aerochaco.net and Iberia has no Salta nor Iguazu among destinations... Does anybody know if aerochaco or macair or somebody else really operates these flights (Resistencia to Iguazu and Salta) and where we can buy or book tickets?
