Both Buenos Aires Ezeiza International and Aeroparque downtown airports are returning to normal operations after an ash cloud from the erupted Chilean Puyehue volcano reached the Argentinean capital.
The airports remained closed most of Tuesday, 7 June.
An Ezeiza airport spokesman says that, after the authorities confirmed that the ash cloud over Buenos Aires disappeared by 16:00 local time, flight operations could be restarted, except to the Patagonian region.
Argentina's national airline Aerolineas Argentinas says that it expects regular operations on 8 June to all international destinations and for domestic routes to cities located in Northern and Central Argentina, although domestic flights might be subject to schedule changes. All southbound flights will remain cancelled although the airline says that it will reassess on Thursday, 9 June some destinations, such as Ushuahia, that remained isolated since the eruption on 4 June.
The online flight information system of airport operator Aeropuertos Argentina 2000 continues to show a number of flight cancellations and delays, which the airport source attributes to "aircraft rotation adjustments".
