Because the ash cloud from Chile's Puyehue-Cordon Caulle volcano passes over the south of Australia, the times of departure for flights from Australia to Vietnam by Vietnam Airlines on 22June2011 are to be changed. Time of departure for VN 780 from Melbourne to Ho Chi Minh City (Saigon) is to be changed from 10:35 A.M to 12:35 P.M (local time). The time of departure for VN 782 from Sydney to Ho Chi Minh City is changed from 10:15 A.M. to 14:15 (local time). Earlier, on 21June2011 Vietnam Airlines flights' times from Ho Chi Minh City to Melbourne and Sydney were also changed by ash from the volcano.
