Key takeaways
  • Soekarno-Hatta and four other airports around Jakarta and West Java reopened just after midnight Tuesday following a two-day ash-related closure.
  • The shutdown disrupted nearly 3,000 flights, including 622 international services, affecting approximately 341,000 passengers.
  • Authorities kept some airports closed beyond the initial reopening to allow thorough inspection and cleaning of runways and aircraft, even where ash tests came back clear.
  • Anak Krakatau's main eruption phase ended Sunday but the island remained volcanically active as of Tuesday morning.
  • Indonesia's Transportation Minister cited highly dynamic wind conditions as the key reason for a conservative, phased reopening approach.

Jakarta's Airports Back Online After Anak Krakatau Eruption

Flights in and out of Jakarta resumed in the early hours of Tuesday after volcanic ash from Anak Krakatau forced a two-day shutdown that grounded close to 3,000 services and left around 341,000 passengers stranded or rerouted. The reopening brought relief to one of Southeast Asia's busiest aviation corridors, though authorities stressed the situation remained dynamic.

Which Airports Closed and When They Reopened

According to DT Next, which first reported the details, Transportation Minister Dudy Purwagandhi confirmed that Soekarno-Hatta International Airport and Halim Perdanakusuma Airport in Jakarta, Husein Sastranegara Airport in Bandung, and two smaller airports in Banten province all reopened just after midnight on Tuesday. Atung Bungsu Airport in Pagar Alam, South Sumatra, had already returned to normal operations on Monday morning.

Three airports remained closed until at least 10 am local time, including Radin Inten II Airport in Lampung at the southern tip of Sumatra, even as conditions at some facilities were improving.

Why the Extended Closure Was Necessary

Purwagandhi explained the cautious timeline in a statement: wind direction was described as highly dynamic, and officials wanted certainty that ash had fully cleared the airspace around Anak Krakatau before resuming full operations. Notably, tests at several airports showed no detectable ash on surfaces, yet the extended window was used to inspect and clean runways, taxiways, and aircraft that could have been exposed. It is a reminder that volcanic disruptions carry an engineering and safety tail that outlasts the eruption itself.

The continuous eruption, which included lava fountains and audible booms, ended on Sunday. By Tuesday morning the volcanic island remained active, keeping authorities on alert.

Scale of the Disruption

The two-day closure affected 2,961 flights in total, of which 622 were international services. For context, that is a significant share of the weekly international capacity connecting Jakarta to destinations across Asia, Australia, the Middle East, and Europe. Travelers with onward connections, group tours, and time-sensitive business travel bore the brunt of the cancellations and delays.

Why It Matters for Hosts

Independent accommodation and experience operators in Jakarta, Bandung, and the wider West Java region should treat this event as a practical prompt to review their cancellation and rebooking policies for force-majeure situations. When nearly 341,000 passengers face sudden itinerary changes, properties that communicate quickly, offer flexible date adjustments, and maintain clear emergency contact details are far better positioned to retain bookings and guest goodwill than those that default to rigid no-refund stances. It is also worth establishing a simple monitoring routine: Indonesia's Geological Agency (Badan Geologi) publishes volcanic activity updates, and a brief daily check during periods of elevated activity can give hosts a meaningful head start before guests start calling. Keeping a short, pre-written guest communication template ready for disruption scenarios can save hours of reactive work when the next closure happens.
