Volcanic ash from the Chilean Puyehue volcano continues ground air travel in parts of Argentina and Uruguay more than a week after the initial eruption, with some ash reaching as far as Australia and New Zealand.
On 13 June Buenos Aires' Ezeiza and Aeroparque airports were forced to close down again as new ash clouds reached the region. Uruguay's capital Montevideo is also suffering massive flight cancellations, although a Montevideo airport source says that the airport "is not closed to operations".
The online flight information of Ezeiza, Aeroparque and Montevideo's Carrasco International airport are showing that all flights were cancelled on Monday morning.
All airports in Southern Argentina also remain closed, although Aerolineas Argentinas has flown some Airbus A340 relief flights to Ushuaia, South America's southernmost city, which is currently linked with Buenos Aires through a combined ferry and 2.500km long road connection.
Over the weekend, portions of the ash cloud reached Australia and New Zealand, causing some minor disruptions and rescheduling of local flights.
