Buenos Aires Ezeiza Airport and Aeroparque in Argentina are still closed due to an ash cloud in South America. Flights to and from the airports have been cancelled after the airspace closed, although it has shifted away from other airports in the region. Flights in Australia and New Zealand were also cancelled at the weekend but have now resumed. However it is thought that it will take up to Wednesday for schedules to return to normal and there is a continued threat that the Chilean volcano will erupt again. TAM, LAN and Aerolineas Argentinas flights are said to be affected.
