Some of the flights cancelled on June 9, eight days after a Chilean volcano started erupting , has still been held in abeyance due to ash cloud created by the volcanic eruption.

Qantas Airways Ltd. (QAN), Australia’s biggest carrier has extended its cancellation. Qantas’ Jetstar budget brand has stopped running 66 flights and Virgin Blue Holdings Ltd. will cancel three services to New Zealand today.

“We have weather conditions that impact on the movement of the ash plume and we believe that it’s simply not safe for us to be able to fly,” Wirth said in a televised media conference on Sky News Television.

“There’s too many uncertain facts and until we know exactly where the ash plume is, exactly what the density of it is, Qantas believes it is absolutely prudent to suspend services.”
