Ash cloud movements continue to disrupt airline service in Chile and Argentina, as LAN and Aerolineas Argentinas are partially re-launcing operations to southern regions in Chile and Argentina.
The Puyehue volcano in Southern Chile erupted on 3 June causing the prolonged closure of Argentina's southern region to commercial air transportation. Ash particles travelled as far as Australia and New Zealand, disrupting flights from Chile and Argentina to those countries.
While LAN confirmed that it has relaunched flights to Concepción, Temuco, Valdivia, Puerto Montt, Balmaceda and Punta Arenas on 23 June, the airline said that its Argentinean domestic operations to Bariloche, Neuquen and Comodoro Rivadavia remain cancelled.
An Aerolineas Argentinas source at Buenos Aires' Ezeiza airport said that the carrier is operating certain Airbus A340-operated relief flights to destinations in the country's far south, particularly Ushuaia. "We are unable to predict exact schedules as the aircraft may be routed over the Atlantic or over the Pacific", he said.
On late 23 June, Aerolineas announced the relaunch of a limited number of scheduled fights to Rio Gallegos, El Calafate and Ushuaia starting 24 June, although all flights are "subject to recommendations from the National Meteorological Service and ANAC (CAA)".
