Seven Airports Shut as Volcanic Ash Spreads Across Indonesian Airspace
An eruption of Mount Anak Krakatau on Saturday, September 6, 2026, sent a plume of volcanic ash across a wide stretch of Indonesian airspace, forcing authorities to close eight airports and cancel or delay hundreds of flights. By Monday morning, seven of those airports were still shut, leaving roughly 270,000 passengers stranded and more than 2,300 flights affected.
Soekarno-Hatta International Airport, Jakarta's main gateway, was among the airports that remained crowded on Monday as passengers lined up to seek refunds or rebook onto later departures. Many were told the earliest available slots were on Tuesday. The closure at Soekarno-Hatta and the other affected airports was extended to 6pm local time (1100 GMT) on Monday.
What Officials Have Said
Berton Panjaitan, spokesperson for Indonesia's National Disaster Mitigation Agency, confirmed the scale of the disruption in a statement to Anadolu Agency, which first reported these figures. He described the airport closures as a precautionary measure driven by aviation safety considerations rather than direct structural damage, and said the situation was being reviewed continuously based on how the ash cloud dispersed.
"The status of these airports is continuously reviewed based on volcanic ash dispersion and aviation safety," Panjaitan said, adding that operations would resume as soon as conditions permitted.
One airport, Atung Bungsu Airport in Pagar Alam, had already resumed normal operations by 9am Monday, suggesting that the ash cloud's reach was shifting rather than static.
The Volcano and Its Location
Mount Anak Krakatau sits in the Sunda Strait, approximately 150 kilometres from Jakarta. The volcano has a history of significant activity and is closely monitored by Indonesian geological authorities. Its position between Java and Sumatra means eruptions can affect flight corridors serving both islands simultaneously, which explains why the disruption spread well beyond the capital.
Traveler Guidance
Anyone with flights into or out of Jakarta or other affected Indonesian airports during this period should contact their airline directly before heading to the terminal. Long queues for rebooking were reported at Soekarno-Hatta on Monday morning, and many passengers were pushed to Tuesday departures at the earliest. Travelers connecting through Jakarta to onward domestic or international destinations should build in significant buffer time and monitor airline communications closely until ash dispersion data confirms airspace is clear.
For those already in Bali, the Jakarta Globe reported that stranded passengers were also waiting at I Gusti Ngurah Rai International Airport in Kuta, where some Jakarta-bound flights were cancelled.
Why It Matters for Hosts
Independent accommodation operators near any of the seven affected airports should prepare for a surge in walk-in or last-minute booking requests from stranded travelers who cannot reach their original destination. Keeping a small block of rooms unallocated during active volcanic events, and having a clear, visible policy for short-notice extensions, can turn a disruption into a loyalty-building moment. It is also worth proactively communicating with guests who have upcoming arrivals: a brief message acknowledging the situation and offering flexible check-in windows costs nothing and significantly reduces guest anxiety during uncertain travel conditions.
