Key takeaways
  • Anak Krakatau erupted from late Friday 4 September, sending ash columns as high as 50,000 feet over western Indonesia.
  • Soekarno-Hatta International Airport was suspended from the early hours of 6 September and remained closed until at least 17:30 local time.
  • Over 300 flight movements were affected, including 58 international services; Singapore was the most disrupted overseas destination.
  • Three additional airports, including Halim Perdanakusuma and Radin Inten II in Lampung, were also temporarily closed.
  • Passengers were advised to check directly with airlines and airports as recovery schedules remained subject to changing ash conditions.

Jakarta Airports Shut Down as Anak Krakatau Erupts

Volcanic ash from Anak Krakatau brought flight operations at Jakarta's Soekarno-Hatta International Airport to a standstill on Sunday, 6 September 2026. What began as a short-term suspension stretched through the afternoon, with the airport remaining closed until at least 17:30 local time as ash continued to drift across the region's airspace.

Anak Krakatau, the active volcanic island sitting in the Sunda Strait between Java and Sumatra, had been showing eruptive activity since late Friday, 4 September. Indonesia's National Disaster Management Agency, BNPB, reported rumbling and lava-fountain activity over that period.

Scale of the Disruption

The figures released by different agencies cover different time windows and should be read accordingly. Indonesia's civil aviation authorities recorded 209 affected flight movements and roughly 22,800 passengers in an earlier count. A later tally cited by Channel NewsAsia, sourced to the airport operator, put the total at 301 flight movements disrupted between 01:30 and 13:30, including 58 international services and 10 cargo flights.

International routes to and from Singapore, Hong Kong, Sydney, Seoul, Doha, Amsterdam and Kuala Lumpur were among those affected in the earlier reporting period. Singapore was the single most disrupted overseas destination. Singapore Airlines cancelled 19 services between Singapore and Jakarta scheduled for that Sunday, including some that had already been rescheduled once. The airline told customers who had booked directly that they could request alternative flights or refunds.

Soekarno-Hatta was not the only airport affected. BNPB confirmed temporary closures at Halim Perdanakusuma Airport in Jakarta, Radin Inten II Airport in Lampung and Budiarto Curug Airport, all due to volcanic ash.

How Far the Ash Spread

Indonesia's meteorological agency, BMKG, detected ash over Banten, Jakarta, West Java and Bengkulu. Monitored ash layers reached altitudes of 20,000 feet and 50,000 feet, triggering aviation weather warnings and notices to pilots across a wide swathe of western Indonesia.

Authorities urged all passengers to check directly with airlines and airports before travelling, noting that restrictions and recovery timelines remained subject to change depending on ash conditions.

Why It Matters for Hosts

For independent accommodation operators in Jakarta and the surrounding region, a volcanic ash closure of this scale means guests may arrive late, miss connections entirely, or need to extend their stays at short notice. Having a clear, written policy for late arrivals and flexible check-out, communicated proactively when disruptions are announced, reduces friction for both sides. Keeping an eye on BMKG and BNPB updates gives hosts an early signal to reach out to incoming guests before those guests start scrambling for information themselves. Building relationships with nearby transport providers who can assist with last-minute airport transfers or alternative routing is equally practical preparation for an event that, given the region's volcanic activity, is unlikely to be a once-in-a-generation occurrence.
