Bali flight cancellations continue as volcano spews ash, with indications chaos could continue

Flights to and from Bali have been cancelled for a second day as an ash cloud impacts safety.

Jetstar has announced flights in and out of Denpasar Airport are cancelled until at least midday tomorrow.

"Impacted customers will be notified directly and will be provided with a range of options," it said.

In an indication that the airline expects ongoing disruption, customers booked between now and Sunday can now also rebook or cancel flights.

It says it is planning to put extra flights on using bigger planes at some point, with Aussies already on the holiday island stuck.

The havoc is a result of Indonesia's Mount Lewotobi Laki Laki volcano spewing towering columns of hot ash high into the air since a huge eruption last week.

Virgin Australia says as well as cancelling flights today, tomorrow's flights to and from the island are delayed.

It said it is contacting affected passengers.

It is also asking passengers due to travel between now and Saturday to keep an eye on the website.

They can also rebook for a later date within the next two weeks, or get a refund.

"The safety of our guests and crew is our highest priority," Virgin Australia said in a statement.

While some Qantas flights yesterday took off as scheduled, one departure last night was turned around.

Four Virgin Australia flights were cancelled yesterday - two of those into Denpasar and two departures from the airport.

Meteorologists are continuing to monitor the situation.

A spokeswoman from the Insurance Council of Australia said passengers should contact their travel insurance provider to see if they can make a claim.

"If travel insurance was purchased before travel and before the volcanic event occurred, the policy covers this kind of event, and there was a financial loss, then the customer will be able to make a claim, " a spokeswoman said.

"Any policy purchased after the eruption is unlikely to cover financial losses arising from the event."

Volcano erupted last week

Activity at the volcano on the remote island of Flores, in East Nusa Tenggara province, has increased since last Monday's initial eruption.

Last Thursday, authorities expanded the danger zone as the volcano erupted again.

Friday's activity saw the largest column of ash so far recorded at 10 kilometres high, Hadi Wijaya, the head of the Centre for Volcanology and Geological Disaster Mitigation, told a news conference.

Wijaya said volcanic materials, including smouldering rocks, lava, and hot, thumb-size fragments of gravel and ash, were thrown up to eight kilometres from the crater on Friday.

There were no casualties reported from the latest eruption as the 1584-metre volcano shot billowing columns of ash at least three times on Saturday, rising up to nine kilometres, the volcano monitoring agency said.
