Jetstar, Virgin cancel Bali flights

Jetstar has joined Virgin in cancelling flights in and out of Bali as volcanic ash continues to cause havoc to travel plans.

Jetstar says forecasts indicate the ash cloud from Mount Raung is likely to cause delays over the next 24 hours.

"Jetstar has cancelled all flights in and out of Bali for the rest of the day," the airline said in a statement.

"We will have to cancel more services tomorrow if flying conditions do not improve overnight."

The volcano has disrupted flights since it began spewing the corrosive, silica-based ash last month.

Virgin will provide another update on Wednesday evening.
