Current Status: Are Jakarta Airports Closed Today?
As of Monday morning, September 7, 2026, publicly available information indicates that both of Jakarta’s main airports, Soekarno-Hatta International Airport (CGK) and Halim Perdanakusuma International Airport (HLP), remain temporarily closed due to volcanic ash from Anak Krakatau.
Indonesia’s transport authorities have extended aerodrome closure notices into September 7 for eight airports affected by ash dispersal, including Soekarno-Hatta and Halim in the Greater Jakarta area. A notice to airmen (NOTAM) referenced as A3368/26 updates earlier restrictions and keeps Soekarno-Hatta closed while conditions are reassessed. Similar NOTAMs apply to Halim and several regional airports linked to the same ash event.
Regional meteorological and aviation bulletins describe a persistent volcanic ash cloud over parts of western Java and southern Sumatra, affecting airspace used by flights into and out of Jakarta. Airspace management and airport operations data suggest that any reopening will depend on sustained improvement in ash concentrations and wind patterns over the capital region.
Travelers should therefore expect that scheduled passenger operations at both Jakarta airports on September 7 are heavily disrupted, with large numbers of cancellations and rolling delays even for flights that may eventually operate once restrictions start to ease.
How Anak Krakatau Triggered the Shutdown
The disruption follows a significant escalation in activity at Anak Krakatau, the volcanic island located in the Sunda Strait between Java and Sumatra. Monitoring reports show that the volcano entered a more active phase in late July 2026, with continued eruptions, and then produced an especially ash-rich episode in early September.
On Sunday, September 6, international news coverage reported a strong eruption that sent ash thousands of meters into the atmosphere, drifting toward the densely trafficked air corridors around Jakarta. Aviation advisories and satellite-based ash detection products indicated that ash plumes spread across western Java and the southern approaches to the capital’s airspace.
In response to the deteriorating conditions, Indonesia’s air navigation service provider issued NOTAMs temporarily closing Soekarno-Hatta and several other airports on September 6. Initial closures were time-limited but were then extended as updated observations continued to show volcanic ash within key approach and departure paths.
By the evening of September 6, cumulative impacts were already significant. International wire reports estimated that more than two thousand flights across multiple airports had been canceled or heavily delayed over the weekend, with hundreds of thousands of passengers affected as the new week began.
Airlines Cancel and Reroute as Ash Cloud Persists
Major Indonesian and regional airlines have reacted by canceling, rerouting, or rescheduling services to and from Jakarta and other affected airports. A public update from Lion Group on September 7 states that multiple flights using Soekarno-Hatta and Halim are canceled until at least 6:00 p.m. local time, explicitly citing the continued closure of both airports due to Anak Krakatau ash.
Low cost and full service carriers in the region are also adjusting their operations. AirAsia, for example, has published notices explaining that the Anak Krakatau ash cloud is affecting routes that traverse western Indonesian airspace, leading to cancellations and delays on selected services. Some airlines are rerouting aircraft to alternative airports that remain open or adjusting flight paths to avoid contaminated airspace.
International connections are particularly affected where Jakarta acts as a hub or transit point. Travelers on long haul itineraries to or from Europe, the Middle East, and North Asia are experiencing missed connections and enforced overnight stays as airlines wait for clearer guidance on when Jakarta’s airports can safely reopen.
Given the dynamic nature of ash dispersion, airlines are updating schedules frequently throughout the day. Industry statements emphasize that safety margins for volcanic ash are conservative, so even marginal improvements in visibility or local air quality may not translate immediately into restored flight operations.
What Travelers Flying Via Jakarta Should Expect
For passengers booked to travel through Jakarta on September 7 and in the days that follow, disruption is likely to remain substantial. Revised government statements on the morning of September 7 extend the closure of eight airports affected by Anak Krakatau ash at least into the evening, and later updates on the same day prolong some closures until 23:59 local time.
These measures apply to a cluster of airports around the Sunda Strait, including Soekarno-Hatta, Halim Perdanakusuma, Radin Inten II in Lampung, Budiarto in Banten, and several smaller facilities. The broad geographic scope of the restrictions indicates that decision makers are still observing elevated ash risk in the wider region, not only directly above the volcano.
Travelers already in transit are being rebooked on later flights where possible, though limited spare capacity and continued uncertainty over reopening times mean that some passengers are facing multi-day delays. Airlines are encouraging customers to monitor their booking status through official websites and apps, rather than relying on static timetables that may not reflect the latest NOTAM-driven operational changes.
Those with imminent departures to Jakarta from overseas hubs should be prepared for last minute cancellations, rerouting through alternative Southeast Asian airports, or involuntary itinerary changes that bypass Jakarta altogether. Flexible ticket policies and change fee waivers are being applied by some carriers, but the exact options vary by airline and fare type.
Outlook for the Coming Days
Forecasts from Indonesia’s meteorological agency indicate that Anak Krakatau remains under close observation, with 24 hour monitoring of both eruptive activity and ash transport. Volcanic ash advisories and aviation weather messages are being updated regularly as new plume heights, wind data, and dispersion models become available.
Transport authorities have stated in public briefings that closed airports will only reopen once ash is confirmed to have moved away from critical flight paths and once on the ground inspections confirm that runway and aircraft operations can be conducted safely. Historical contingency plans for volcanic events in Indonesia show that reopening can be relatively rapid once ash concentrations fall, but the timing depends entirely on the volcano’s behavior and prevailing winds.
For now, publicly accessible government notices indicate that closures at the main Jakarta airports are in effect through at least late on September 7, with extension or partial lifting possible at short notice. Travelers with flights beyond that time window should follow updates from airlines and official aviation channels closely, as the situation can change within hours.
In practical terms, anyone planning to depart from or arrive in Jakarta this week should treat their itinerary as tentative. Until Anak Krakatau’s ash output subsides and sustained improvement is confirmed by monitoring agencies, Jakarta’s role as Indonesia’s primary aviation hub will remain under significant strain.
