Just after a few hours, the Mount Agung volcano gushed a 2500 metre column of ash and smoke, the Indonesian tourist island of Bali closed its global airport.
According to The Star, the airport was shut on Friday (June 29) and will remain close until 7pm local time.
It's far from the first time Agung has interrupted travel plans for WA holiday-makers, with a November eruption past year causing chaos to flight schedules.
The eruption sent an ash column of 2,500 metres (8,200 ft) into the air and a reddish flame was visible in Mount Agung's crater, Sutopo Purwo Nugroho, a spokesman for the agency said in the statement.
The major reason for cancelling the flights during a volcanic eruption is that it can damage engines, clog fuel and can even hamper visibility.
The budget airline said in a statement that the Ngurah Rai International Airport was closed today, from 3 am to 7 pm (same time as in Malaysia).
A volcanic ash cloud from Mount Agung has stopped flights in and out of the Indonesian island of Bali, disrupting the holiday plans of thousands.
"The airport could be closed again if the eruption affects flight safety".
Tourists on the island were subjected to hours of travel misery as hundreds of flights were grounded and Bali's worldwide airport was temporarily shut.
AirAsia's Flight QZ509, scheduled to leave Singapore at 9.05pm to Denpasar was also cancelled.
Among the airlines serving the resort island, Garuda Indonesia, Sriwijaya and Indonesia Air Asia said they were working to help stranded passengers.
Eruptions lasted for nearly a year, with the volcano falling silent again until September 2017 when several hundred earthquakes struck locally.
Indonesia, an archipelago of more than 250 million people, sits on the Pacific "Ring of Fire" and is prone to earthquakes and volcanic eruptions.
The alert level was sitting on a three, with a 4km exclusion zone around the mountain and tremors being experienced at the site throughout the afternoon.
