Flights out of Buenos Aires have been canceled once again due to ash from Chile's Puyehue volcano.

Flights to and from Jorge Newbery Metropolitan Airport and Ezeiza International Airport were suspended on Sunday, reported La Nacion.

The volcano erupted in June after sitting dormant for half a century and severely disrupted air travel in the southern hemisphere. Flights to the Argentine city of Bariloche only resumed last month.

The ash poses a significant threat because if it us sucked into engines, it can be transformed into molten glass by the high temperatures and potentially cause an engine to fail, reports the Telegraph.
