Qantas, Jetstar and Tiger Airways have all cancelled flights this morning, as strong winds carry ash particles from Puyehue Volcano in Chile across the southern hemisphere.

Air travel in South America also continues to be disrupted, with flights in and out of the Argentine and Uruguayan capitals cancelled.

Qantas said flights to and from New Zealand and Tasmania will remain suspended for the duration of today.

However, flights from Melbourne are expected to resume from 13:00.

Passengers in Australia have been warned to expect delays as airlines attempt to clear a massive backlog of flight cancellations.

As many as 60,000 travellers with Qantas are believed to have been affected since last night.

Jetstar cancelled 66 flights on Sunday, affecting 8,600 passengers, but was hoping to return to schedule today.

Tiger Airways is resuming operations from 17:00 today following a number of cancellations over night.

“Tiger Airways is working hard to minimise any inconvenience to passengers affected by the cancellations,” read a statement from the low-cost carrier.

South America

In South America, Copa and American Airlines both cancelled flights into the Uruguayan capital, Montevideo, yesterday as authorities tracked ash over the city.

Flights to and from Argentina’s capital, Buenos Aires, and other main cities were also cancelled.
