Airline flights resumed to Bariloche on January 13 after four months with no service due to a combination of ashes in the atmosphere from the Puyehue Volcano in Chile and closure of the airport for maintenance work. The first landing was by an Aerolineas Argentinas 737-500 operating flight AR1682 from Buenos Aires - Aeroparque.
Full schedules of commercial flights to BRC ceased on June 4, 2011 when the long-dormant volcano erupted with large amounts of ash blowing into the sky. Since then, BRC only received five Aerolineas Argentinas flights for a short time in September and one or two other flights, such as by Andes Lineas Aereas, when the ash temporarily ceased.
Bariloche is an Argentine city located on the shores of Lake Nahuel Huapi in the internationally-famous Patagonia region, with a major ski resort nearby, Cerro Catedral. BRC receives many charter flights directly from Brazil in the winter season from June through September but the volcanic ash caused many of these to be cancelled or routed to Esquel (EQS), some four hours south of BRC, with pax taken to Bariloche by ground transfers.
