'Stranded': Bali travel chaos after flights grounded due to ash cloud from deadly volcano

A volcano on a remote Indonesian island continues to spew towering columns of hot ash into the air, making it too dangerous for flights to land or depart from Bali's international airport.

Travellers have been stranded at Bali’s I Gusti Ngurah Rai airport since flight cancellations began at the weekend.

“The airline did not provide accommodation, leaving us stranded at this airport,” said Charlie Austin from Perth, Australia, who was on vacation in Bali with his family.

It is unclear when the ash cloud will clear and allow the airport to resume normal operations.

Mount Lewotobi Laki Laki volcano on the island of Flores in East Nusa Tenggara province has been shooting hot ash high into the air since it first erupted on 4 November, killing ten people so far and injuring dozens of others.

The 1,584-meter volcano shot up ash at least 17 times on Tuesday, with the largest column recorded at 9 kilometres high, the Center for Volcanology and Geological Disaster Mitigation said in a statement.

Bali flights: Are all departures and arrivals cancelled?

I Gusti Ngurah Rai airport's website currently shows most international departures for today (Wednesday) as either cancelled or delayed, while a few flights, to destinations such as Istanbul and Kuala Lumpur, do appear to be taking off as scheduled.

The advice to passengers is to contact your airline or check their website or social media channels before leaving for the airport.

Jetstar Bali flights: Australian airlines worst hit by cancellations

Australian airlines use Bali's international airport more than any others, since Bali is a very popular holiday destination with Australians.

Budget airline Jetstar has paused its flights to Bali until at least Thursday, it said on its website, saying it was “currently not safe” to operate the route.

They say they understand that some passengers may no longer wish to fly to Bali, in which case anyone with flights booked between 13 and 17 November have the option to postpone their flight by three weeks or get credit to use with the airline. For full details on your options, check their website.

Are passengers on Bali flights entitled to a refund or compensation?

Rules vary by country or region but EU airlines have to offer a refund or new flight if they cancel your flight. However if the cancellation is due to weather-related events, they sometimes claim this is an "act of God" to get out of paying passengers.

However for this volcano affecting Bali, some airlines have already said they will cover refunds or offer new flights so the chances are quite good.

Travel insurance is designed to cover unforeseen events, such as emergency medical expenses, lost or stolen belongings and last-minute cancellations.

In some cases, you can be reimbursed if your trip is cancelled due to extreme weather - but certain conditions usually apply.

Check your policy for a list of covered reasons for trip cancellation, as these vary by provider. Some may provide add-ons for weather-related circumstances.

Mount Lewotobi Laki Laki volcano: 9 kilometre high ash cloud

Authorities on Tuesday expanded the exclusion zone as the volcano erupted again to 9 kilometres high. Volcanic materials, including smoldering rocks, lava, and hot, thumb-size fragments of gravel and ash, have been thrown up to 8 kilometres from the crater since Friday.

About 6,500 people were evacuated in January after Mount Lewotobi Laki Laki began erupting, spewing thick clouds and forcing the government to close the island’s Fransiskus Xaverius Seda Airport. No casualties or major damage were reported, but the airport has remained closed because of seismic activity.

Lewotobi Laki Laki is one of a pair of stratovolcanoes in the East Flores district of East Nusa Tenggara province, known locally as the husband-and-wife mountains. 'Laki laki' means man, while its mate is Lewotobi Perempuan, or woman. It’s one of the 120 active volcanoes in Indonesia, an archipelago of 280 million people.

The country is prone to earthquakes, landslides and volcanic activity because it sits along the 'Ring of Fire', a horseshoe-shaped series of seismic fault lines around the Pacific Ocean.
