Jakarta's Main Airport Halted by Volcanic Ash
Volcanic ash from an ongoing eruption of Mount Anak Krakatau forced Indonesia's Soekarno-Hatta International Airport to suspend all flight operations on Sunday, September 6, 2026, extending a halt that had originally been scheduled to end at 5:30 am through to at least 9:30 am local time. By the time the suspension was lifted, 209 flights had been affected, including a significant number of international services.
What Happened and Where the Ash Reached
Mount Anak Krakatau, situated roughly midway between Java and Sumatra in the Sunda Strait, began erupting late on Friday. Volcanic ash was detected at the airport early Sunday morning. Indonesia's meteorological agency, BMKG, reported ash columns reaching 6,000 metres on the Java side of the volcano and a plume of up to 15,000 metres on the Sumatra side, with ashfall recorded across parts of Banten province.
The disruption spread well beyond Jakarta's airspace. International routes to and from Singapore, Kuala Lumpur, Guangzhou, Hong Kong, and Doha were among those delayed or cancelled, according to the airport's own website. Singapore Airlines confirmed it cancelled two Jakarta flights on Saturday. A third flight originally scheduled for Saturday night was pushed to Sunday afternoon, and a Sunday morning departure from Jakarta to Singapore was delayed until 3:50 pm. The carrier noted that the situation remained fluid and that further flights between Singapore and Indonesia could be affected.
On the Ground in Banten and Beyond
The eruption's impact was felt well outside the airport perimeter. Several schools cancelled activities on Saturday, and local media outlet Kompas reported that residents and students experienced eye irritation from ashfall. Fishermen suspended trips due to the eruption. Indonesia's disaster mitigation agency, BNPB, advised the public to wear masks and eye protection, limit outdoor activity, cover water sources, and drive carefully given reduced visibility.
BNPB spokesperson Berton Panjaitan confirmed there was no imminent tsunami risk, a reassurance that carries particular weight given the volcano's history. A 2018 eruption triggered a tsunami that killed hundreds and injured hundreds more across Java and Sumatra. Anak Krakatau itself emerged from the caldera left by the catastrophic 1883 Krakatoa eruption, which killed more than 36,000 people.
Indonesia sits on the Pacific Ring of Fire, making seismic and volcanic activity a recurring feature of the landscape rather than an exceptional event.
Why It Matters for Hosts
For independent accommodation operators in Jakarta and the wider Banten and West Java region, this disruption is a reminder that volcanic events can eliminate an entire day's arrivals with little warning. Hosts should maintain a clear, up-to-date cancellation and rebooking policy that explicitly covers force-majeure events such as volcanic eruptions and airport closures. Communicating proactively with incoming guests via direct messaging as soon as a suspension is announced, rather than waiting for guests to ask, builds trust and reduces no-show confusion. Keeping a list of alternative transport options into the city, such as overland routes from Bandung or Surabaya for guests rerouting, is a practical addition to any guest information pack.
