Volcanic activity cancels Singapore to Jakarta flights, stranding passengers

Disruption overview

Flights from Singapore to Jakarta were canceled on 7 September 2026 as volcanic activity across Indonesia, including activity at Anak Krakatau, continued to disrupt air travel. For passengers already in transit, the disruption meant being stranded in Singapore, facing limited seats on later flights, or accepting longer reroutes to other Indonesian cities. One traveler, Dina Indrasafitri, had already flown from Sydney and only learned at about 6:00 am that her onward Monday flight would not operate. Because the cancellations were caused by a natural disaster outside the airline's control, compensation under EC 261 is unlikely, but airlines should still offer rebooking or refunds and provide care while you wait.

Disruption details

Passengers traveling from Singapore to Jakarta faced cancellations on Monday, 7 September 2026, as heightened volcanic activity in Indonesia continued to disrupt air travel. For people already mid-journey, that meant being stranded in transit, watching plans unravel, and trying to work out whether to wait, reroute, or turn back.

One of those passengers was Dina Indrasafitri, an Indonesian student at Western Sydney University. She left Sydney on Sunday, 6 September 2026, for the semester break and arrived in Singapore at about 9:00 pm local time. She was due to continue to Jakarta on Monday afternoon, but at around 6:00 am on 7 September she received notice that her onward flight had been canceled.

The cancellations are tied to a broader run of eruptions across Indonesia's volcanic arc, including activity at Anak Krakatau. Airlines have been adjusting schedules in response to aviation advisories, and the disruption is still affecting travel on routes into Indonesia.

For passengers, this wasn't just a timetable change. Once in Singapore, Dina and other travelers were offered free rebooking or rerouting to other Indonesian cities. But later flights to Jakarta were already close to full, and the alternative routes on offer would have added much longer travel times.

That kind of knock-on effect can spread quickly. When carriers waive change fees and allow itinerary changes during a natural event, seats on the remaining services can disappear fast. In this case, the pressure appears to have extended beyond Jakarta to other major Indonesian gateways as stranded passengers searched for any workable route.

Dina also said there had been no warning in Sydney that her onward journey might be at risk, even though aviation advisories had been issued in the days before departure. For travelers, late information can make an already difficult situation harder, especially when the cancellation only becomes clear after the first part of the trip is complete.

The disruption has also left her weighing a difficult decision. With a new academic term approaching in Australia, she is considering whether to give up the holiday altogether and return to Sydney instead of waiting for a seat to Jakarta.

If your flight is canceled in this kind of situation, your airline should still help with the basics:

• Offer rerouting or a refund.

• Provide food and refreshments during longer waits.

• Arrange accommodation and transportation if you're stranded overnight.

• Give practical communication support if the delay stretches on.

Because these cancellations were caused by volcanic activity, compensation under EC 261 is unlikely. When a disruption is caused by circumstances outside the airline's control, airlines generally don't have to pay compensation, even if the impact on passengers is severe.

Although compensation is unlikely here, that doesn't mean you're without support. Your airline should still provide care and assistance, along with rebooking or refund options if your journey can't go ahead as planned.
