The airline has cancelled all flights from Australia to Denpasar on Friday.
A decision will be made by midday on Friday on whether flights will be able to leave Denpasar.
Earlier today, Jetstar and Virgin have confirmed all flights scheduled for the afternoon and evening between Australia and Bali are cancelled because of a volcanic ash cloud over Denpasar airport.
Flights between Australian cities and Bali have been grounded since Wednesday evening because of volcanic eruptions from Mt Raung.
A Jetstar spokesman said the airline might put on additional services in the coming days.
The spokesman said the airline regrets the disruption and has options for passengers who wish to amend their travel plans.
Virgin has asked travellers to call 13 67 89 to change their flight plans.
Both airlines have said they would continue to monitor flying conditions.
