More news on this day
Jakarta’s Soekarno-Hatta International Airport has extended a sweeping suspension of flights as ash from Indonesia’s Anak Krakatau volcano continues to drift over western Java and southern Sumatra, forcing widespread cancellations and stranding tens of thousands of travelers across the region.

Flight suspensions in Jakarta stretch into a second day
The extended halt at Soekarno-Hatta, one of Southeast Asia’s busiest hubs, follows a series of rolling closures that began on Sunday, September 6, after Anak Krakatau sent dense ash clouds tens of thousands of feet into the atmosphere. Publicly available flight notices and local media reports indicate that airport operations were initially paused in the early hours of Sunday and then repeatedly prolonged as the ash plume spread and intensified over Jakarta’s airspace.
By Monday, September 7, Jakarta-based coverage reported that Soekarno-Hatta and at least three other airports had lengthened their shutdowns into the evening, affecting both domestic and international services. Singapore, Kuala Lumpur and other regional gateways have reported diversions or delays on routes linking them with the Indonesian capital as carriers reassess flight paths around the ash cloud.
Notices to airmen (NOTAMs) cited in Indonesian transportation updates extend the closure window for Soekarno-Hatta until at least mid-morning Monday local time, with subsequent revisions pushing some restrictions later into the day. The evolving advisories underscore how quickly volcanic ash conditions can change and how cautiously aviation authorities are moving in response.
Eight airports affected as ash drifts across western Indonesia
The disruption is not limited to Jakarta. According to information published by Indonesia’s Transportation Ministry and summarized by national media, a total of eight airports have faced temporary closures or severe restrictions because of Anak Krakatau’s ash. Alongside Soekarno-Hatta, the list includes Jakarta’s Halim Perdanakusuma Airport, Radin Inten II in Lampung, Husein Sastranegara in Bandung, and several smaller facilities in Banten, South Sumatra and Lampung provinces.
Government communiqués and state news agency coverage describe a cascading series of extension decisions on Sunday, pushing the shutdowns first to late afternoon, then to midnight, and later into Monday morning. Monitoring by the Transportation Ministry suggests that more than 1,500 flights have been delayed or canceled since the eruption intensified, with around 170,000 passengers affected across the eight airports.
Meteorological and volcanology bulletins cited in domestic reports note that ash heights have reached up to around 20,000 feet on the Java side of Anak Krakatau and as high as roughly 50,000 feet on the Sumatra side. That spread has pushed ash into air corridors used by dense networks of short- and medium-haul flights, from island-hopping domestic services to regional routes toward Singapore, Malaysia and Australia.
Safety-first approach shapes Indonesia’s aviation response
Transportation Ministry statements emphasize that reopening decisions will depend on real-time assessments of ash concentration rather than on fixed timelines. Ministry releases and briefings reported by Indonesian outlets explain that aviation authorities are working with air navigation providers, airport operators and the national meteorological agency to track the ash plume’s direction, altitude and density before allowing flights to resume.
Recent monitoring reports indicate that upper-level winds have shifted the ash cloud at around 15,000 feet from a westward to an eastward path, affecting parts of Banten and West Java, including the skies above the Jakarta metropolitan area. This shifting pattern has led to repeated recalibration of closure windows and contingency routing for flights that can still operate safely in unaffected corridors.
Aviation experts consistently flag volcanic ash as a serious hazard because it can damage jet engines, abrade cockpit windows and interfere with critical sensors. In this event, Indonesia’s stepwise extensions of airport closures, reflected across a series of publicly posted notices, show a clear bias toward caution as long as satellite data and on-the-ground observations point to elevated ash concentrations near major flight paths.
Travelers face widespread delays, diversions and rebooking
For travelers, the prolonged suspensions at Jakarta’s main gateway have translated into crowded terminals, long rebooking queues and uncertain departure times. Local news images and social media posts from passengers describe overnight waits at Soekarno-Hatta’s terminals, with many travelers attempting to reschedule flights or reroute via still-open airports in other parts of Indonesia or neighboring countries.
Regional travel forums and airline advisories indicate that some carriers are diverting Jakarta-bound flights to alternative airports, such as Singapore or Surabaya, when operationally feasible. Others have chosen to cancel services outright while waiving change fees and offering flexible rebooking options as they await clearer timelines for resuming normal schedules from Soekarno-Hatta and Halim Perdanakusuma.
Travelers with upcoming itineraries to or from Jakarta are being urged, in airline and airport public channels, to monitor flight-status pages, mobile apps and official airport accounts rather than relying on printed tickets or previously issued schedules. With ash forecasts and closure times shifting throughout the day, same-day confirmation of departure and arrival times has become essential for anyone planning to pass through the Indonesian capital.
What the Anak Krakatau eruption means for near-term travel
Anak Krakatau, located in the Sunda Strait between Java and Sumatra, has shown elevated activity since late last week, according to volcanology updates and satellite imagery shared by regional and international monitoring platforms. The latest eruption phase has produced repeated ash emissions rather than a single explosive event, a pattern that can prolong aviation impacts as plumes are refreshed by new bursts.
Travel industry observers note that Jakarta’s connectivity plays an outsized role in Southeast Asian air travel, making any disruption at Soekarno-Hatta quickly felt across domestic and international networks. The current ash-related closure has already triggered cascading delays and aircraft rotations as airlines reposition fleets and crews, with knock-on effects likely to continue even after the immediate restrictions ease.
While there is no clear timeline yet in publicly available notices for a full return to normal operations, Indonesian transport updates indicate that authorities are reviewing conditions on an ongoing basis. Travelers transiting Indonesia in the coming days may face schedule changes at short notice, especially on routes touching western Java, southern Sumatra and nearby regional hubs that intersect with Anak Krakatau’s evolving ash plume.
