Eruption grounds Jakarta air traffic for most of Sunday
Ash from an ongoing eruption of Anak Krakatau forced the suspension of flight operations at Soekarno-Hatta International Airport on Sunday, 7 September 2026, leaving hundreds of services cancelled or delayed and tens of thousands of passengers scrambling to rebook. The disruption was one of the most significant aviation shutdowns Jakarta has seen from a volcanic event in recent years.
Indonesia's National Disaster Management Agency, BNPB, reported that the volcano had been erupting continuously since approximately 23:07 local time on Friday, 4 September, with activity including lava fountains and audible booming. Ash climbed to flight level 480, roughly 14.6 kilometres above sea level, according to satellite data and information from the Darwin Volcanic Ash Advisory Centre, before drifting mainly west to southwest toward the Java coast.
A closure that kept expanding
Transport ministry information placed the initial airport closure at 01:30 on Sunday. A subsequent BNPB update cited a closure window of 02:08 to 09:30, but the suspension did not hold to that schedule. Channel NewsAsia, which first reported the extended timeline, noted that the closure was pushed out in stages until 17:30. The same outlet, citing an airport advisory, tallied 301 affected flights between 01:30 and 13:30 alone: 233 domestic services, 58 international flights, and 10 cargo operations. An earlier official figure put the total disruption at 209 flight movements and around 22,800 passengers.
International routes to and from Singapore, Kuala Lumpur, Hong Kong, Sydney, Seoul, Doha, and Amsterdam were among those hit. Domestic services to Lampung, Denpasar, and Surabaya also faced cancellations or diversions. Channel NewsAsia reported that Singapore Airlines cancelled 19 Singapore-Jakarta flights on Sunday; the carrier confirmed cancellations and schedule changes tied to the eruption and said eligible customers who had booked directly could seek rebooking or refunds.
Soekarno-Hatta was not the only affected airport. BNPB confirmed that Halim Perdanakusuma in Jakarta, Radin Inten II in Lampung, and Budiarto Airport in Curug were also temporarily closed because of ash. Anak Krakatau sits in the Sunda Strait between Java and Sumatra, placing it within reach of airports on both islands when winds carry ash westward.
At the time of BNPB's update, no deaths or building damage had been reported.
What travelers should do now
Passengers with upcoming Jakarta flights should check directly with their airline and with airport operators before heading to the terminal. Ash dispersion depends on wind patterns and eruption intensity, both of which can shift quickly. Aviation authorities have indicated that operating conditions could change at short notice, so real-time advisories from airlines and Indonesia's transport ministry remain the most reliable source of current status.
Why it matters for hosts
Independent accommodation operators in Jakarta, Lampung, and Bali should prepare for a surge in last-minute booking changes whenever Anak Krakatau is active. Guests stranded by cancellations may need urgent extensions; guests who cannot arrive may request waivers on cancellation fees. Having a clear, publicly visible force-majeure or disruption policy, and being reachable by phone or messaging app during a closure event, can turn a stressful situation into a loyalty-building moment. It is also worth monitoring BNPB alerts directly so you can proactively contact incoming guests before they contact you.
