Volcanic ash from Anak Krakatau shut six Indonesian airports on Sunday, September 6, cancelling 209 scheduled flights at Jakarta's Soekarno-Hatta airport alone in a single morning. The closures mark a sharp escalation from Thursday night's eruption, which we covered in our Anak Krakatau eruption travel caution, and have stranded thousands of travellers across Java, Sumatra and Bali.
Operator InJourney Airports logged the 209 cancellations at Soekarno-Hatta between 1:30am and 9:30am Sunday local time: 160 domestic, 39 international and 10 cargo flights, according to Assistant Deputy for Communication and Legal Affairs Yudistiawan. The airport is under temporary closure after paper-test monitoring detected ash on the airfield.
Which airports are closed by the Krakatau ash?
Six facilities are shut for safety. Alongside Soekarno-Hatta in Tangerang, the list covers Radin Inten II in Lampung, Halim Perdanakusuma in Jakarta, Budiarto and Pondok Cabe in Tangerang, and Husein Sastranegara in Bandung, the last added after midday testing. Bali and Batam airports have also cancelled flights amid the spreading ash.
On Sunday afternoon Transportation Minister Dudy Purwagandhi announced a four-hour extension of the closures at a news conference starting around 1pm, keeping airports shut until about 5pm. Management says resumption will be gradual, depending on how the ash cloud evolves and on flight-safety assessments coordinated with airlines and AirNav Indonesia.
Can affected passengers get a full refund?
Yes. Indonesia's Transportation Ministry has guaranteed full refunds for every passenger whose flight was cancelled because ash affected airport operations, describing the measure as public service so travellers do not suffer financial losses from safety cancellations.
Directorate General of Air Transportation Lukman F. Laisa told ANTARA on Sunday that airlines must notify affected passengers electronically through their registered email addresses and telephone numbers, and that cancellations and refunds can be processed remotely the same way. Minister Purwagandhi separately urged airlines to inform travellers of cancellations promptly. Keep your booking contact details current and watch for the airline's electronic notice rather than queuing at a closed terminal.
What help is available at Jakarta airport?
Soekarno-Hatta has activated its service recovery plan: food and light refreshments for affected travellers, a support hub and command post in Terminal 1B coordinating ground operations, and terminal tenants keeping commercial services open 24 hours to cover basic needs. Passengers should stay in contact with their airline, monitor official airport announcements and use the Terminal 1B post while waiting for recovery updates.
On the ground, state railway operator KAI has added extra Semarang-Jakarta trains, giving stranded travellers a rail alternative while the skies clear. Indonesia has managed ash disruptions before, including the weather-modification operations over Kalimantan's fires that show how fast the authorities move when transport is at stake.
What should stranded travellers do now?
Do not go to a closed airport on speculation. Confirm your flight's status with the airline first, process the refund or rebooking electronically, and consider rail for Java journeys. Ash closures typically lift in stages as test readings clear, so a morning cancellation does not mean the whole week is lost. Travellers with Bali connections should check onward flights separately, since Bali cancellations are being handled airport by airport.

Do I get a refund for a Krakatau-cancelled flight?
Yes. Indonesia's Transportation Ministry guarantees full refunds for flights cancelled because volcanic ash affected operations. Airlines must notify you electronically and process the cancellation and refund remotely using your registered contacts.

Airports reopen only when ash tests clear, so a ticketed flight that operates has been safety-cleared. Travellers should monitor airline and airport announcements, keep plans flexible around Java and Bali, and read our original eruption caution for background on exclusion zones.
