Mount Anak Krakatau Eruption: 2,300 Flights and 268,000 Passengers Affected

Flight activity at four airports remains disrupted by the spread of volcanic ash from Mount Anak Krakatau. Soekarno-Hatta Airport in Tangerang, Halim Perdanakusuma in Jakarta, Husein Sastranegara in Bandung and Radin Inten II in Lampung remained temporarily closed on Monday (7/9/2026).

The closure is expected to last until 18.00 WIB. Amid the situation, airport operators are preparing services for passengers whose journeys have been affected.

“Passenger handling will continue until the airports are declared reopened. Beyond the four airports affected by volcanic ash, the passenger handling regime (SRA) is also being applied at airports with flights bound for the affected airports, adjusted according to the needs of each airport,” said Arie Ahsanurrohim, Corporate Secretary Group Head of InJourney Airports, in a statement on Monday (7/9/2026).

The services cover basic needs whilst passengers await confirmation of their travel plans. Airport operators are also preparing operational support so that affected passengers do not entirely lose access to services whilst at the terminal.

“The closure of the four airports affected by volcanic ash from Mount Anak Krakatau — Soekarno-Hatta Airport in Tangerang, Halim Perdanakusuma Airport in Jakarta, Husein Sastranegara Airport in Bandung and Radin Inten II Airport in Lampung — has been declared a temporary closure, or Aerodrome Closed, on 7 September 2026, estimated until 18.00 WIB for the sake of flight safety, in accordance with the NOTAM issued by AirNav Indonesia,” said Arie.

The impact on flight operations has been considerable. Between 5 September and 7 September 2026 at 09.00 WIB, thousands of flights across the airport network managed by InJourney Airports were affected by the closure of the four airports.

“Between 5 September 2026 and 7 September 2026 at 09.00 WIB, across all airports managed by InJourney Airports, the number of flights affected by the temporary closure of the four airports reached 2,300 flights, with 268,539 passengers affected,” said Arie.

Soekarno-Hatta is among the points with the largest number of affected passengers. Indonesia’s largest airport also briefly provided alternative overland travel to assist passengers impacted by the disruption.

“As part of the SRA, Soekarno-Hatta Airport on 6 September 2026 provided free bus transport services to Yogyakarta, Solo, Semarang and Surabaya for affected passengers,” said Arie.

The flight situation may still change depending on the status of airport closures and volcanic ash conditions. Passengers with flights departing from or heading to the affected regions should confirm their travel status before setting out for the airport.

“Prospective passengers are urged to continually monitor flight status information from the airlines,” said Arie.
