The ash cloud crisis in Australia intensified today as airlines cancelled services to/from Sydney due to ash from the Puyehue-Cordon Caulle volcano in southern Chile. The plume will cause “major disruptions in the next 20 to 48 hours", according to Airservices Australia spokesperson, Matthew Wardell. Qantas and Virgin Australia cancelled all domestic Sydney services from 15:00 and 16:00 today, respectively, and further cancellations are now being announced for tomorrow, 22-Jun-2011.
