Qantas says it will resume flights to and from Bali, after grounding them due to a volcanic eruption near the Indonesian holiday spot that created a dangerous ash cloud.

“Our teams have been working through the night to closely monitor the evolving situation and assess when it’s safe to fly,” the airline said on Thursday morning.

“In good news, this morning conditions have improved allowing us to resume operations between Australia and Denpasar.”

Qantas will operate three flights from Australia on Thursday. They are two flights from Melbourne and Sydney that were delayed on Wednesday and one scheduled flight from Sydney.

Two of the flights will leave Denpasar later on Thursday, the other early on Friday (local time).

Qantas’s budget arm Jetstar will have six return flights to Denpasar from Australian airports. They are four scheduled services and two extra recovery flights.

“We will continue to monitor the changing conditions and volcanic activity and work on plans to operate more recovery flights using aircraft from across the group so that we can get customers on their way as quickly as possible,” an update on the Jetstar website says.

Qantas and Jetstar were contacting affected passengers directly.

Virgin, which cancelled 15 flights between Bali and Australia on Tuesday and Wednesday, is yet to provide any further details on Thursday.

“We are proactively reaching out to guests whose flights have been cancelled to offer an alternative flight option,” it said in an update on its website on Wednesday.

“We are also communicating to guests booked to travel to and from Bali between Thursday (November 14) and Saturday (November 16), encouraging them to stay updated on the latest flight information available via our website.”

All three airlines have cancelled multiple flights since late Tuesday amid safety concerns, leaving passengers stranded in Australia and Indonesia.

The emergency began on Sunday when Mount Lewotobi Laki-laki volcano erupted, spewing an ash column nine kilometres high.

The event in East Nusa Tenggara province, about 500 kilometres from Bali, killed nine people and prompted the evacuation of more than 15,000 people close to the crater.

Other airlines have also cancelled flights to and from Bali. They include airlines operating from Singapore, Hong Kong, Malaysia, India, South Korea, New Zealand and Qatar.
