Which Indonesian airports are open
Anak Krakatau shut eight airports and every one of them is open again. The last two, in Lampung, reopened Tuesday morning. But an open airport is not a full timetable. Radin Inten II came back to ten flights on one route, its Kuala Lumpur service not yet resumed.
Ash closures move in hours, so check what is actually selling before you rebook.
What your airline owes you
Seven kinds of airline, seven different answers. All are flying to Jakarta again. What separates them now is what you can still claim: Qantas until Friday, AirAsia with no deadline, Cathay nothing. The government asked all of them for full refunds, firmer ground on an Indonesian carrier.
Every airport is open, but a seat on a cleared backlog is a different question. Check what is actually selling.
Where to stay if you are stuck in Jakarta
The cheapest beds tonight are not at the terminal. Two Tangerang rooms a few kilometres out undercut anything within walking distance of the gate, and central Jakarta starts higher without being closer. Pay the terminal premium for the short hop back, not the rate.
Nine rooms is a shortlist, not the market. Pick your own nights and area.
How long you can legally stay in Indonesia
Visa-free entry is the trap here. It is the one arrival type Indonesia will not extend, so a cancelled flight can tip you into overstay. Immigration can waive the charge after a disaster, but only if you ask for it.
Singapore and Kuala Lumpur are the nearest exits from Jakarta when your permit runs out before a long-haul seat opens.
Questions
Are flights to Jakarta cancelled?
Not any more, on any of the carriers on this page. Every one of them has resumed its Jakarta flying, and Emirates, the slowest to restart, had all four Dubai rotations operating again by Wednesday. What remains is the backlog behind it. Indonesia’s Transport Minister counted 2,961 flights disrupted through Monday evening, 2,339 domestic and 622 international, with about 341,000 passengers affected; that total covers cancellations, delays and diversions together and no newer figure has been published. Look your own flight up by its number on your airline’s flight status page, then use the airline table above for what you are owed if it still shows cancelled.
Is Jakarta airport open today?
Yes, and so is every other airport this eruption closed. Soekarno-Hatta reopened at 00:01 WIB on Tuesday 8 September with the first movements around 00:30, along with Halim Perdanakusuma and Husein Sastranegara in Bandung, and Budiarto and Pondok Cabe followed just after 03:00. The two Lampung fields, Radin Inten II and Taufik Kiemas, were the last to come back, mid-morning on the same day. Monday’s advertised reopening times were pushed back repeatedly before any of that happened, so treat any reopening time in this episode as provisional. AirNav Indonesia also says ash is still being detected in the airspace and all the second-wave airports remain under monitoring.
Will I get a refund if my flight was cancelled?
Almost certainly, and on an Indonesian airline it is close to settled. The Transport Minister said all airlines must let affected passengers reschedule or refund, and the civil aviation directorate put the figure at 100 percent, processable online. That reaches a carrier Indonesia licenses more firmly than a foreign one, whose terms are its own, so read your conditions of carriage as well as the ministry’s line.
Are Bali flights affected?
Not now. Bali’s I Gusti Ngurah Rai stayed open throughout, and the disruption there was second-hand: 108 flights were cancelled or retimed between Sunday morning and Monday midday, almost all of them on domestic routes to and from Jakarta, Halim and Bandung. Medan’s Kualanamu also kept operating normally while losing 49 flights. Both counts are now history. The general point still holds, though: if you are flying into Bali from outside Indonesia, your flight is far more likely to be affected by what happens at Jakarta than by conditions at Bali itself.
Why do airlines cancel for volcanic ash when the airport is open?
Ash is abrasive and melts inside a hot jet engine, so aircraft avoid it even where the runway is clear. Airlines plan around the ash cloud’s forecast track rather than the airport’s opening hours, and pilots are still being routed around marked polygons where ash is suspected, and AirNav Indonesia says ash remains detectable in the airspace even now the airports are open. There was also a queue on the ground: 178 aircraft were parked at Soekarno-Hatta through the closure and every one needed an airworthiness check for ash damage before it could carry passengers again. That queue is why Jakarta reopened on Tuesday but Emirates did not fly EK356 until Wednesday.
My flight out is cancelled and my visa is about to expire. What happens?
You are covered, but you have to go and ask. Immigration announced an emergency stay permit for this eruption on Monday, the Izin Tinggal Keadaan Terpaksa: valid up to 30 days, extendable, with the overstay charge set to zero rupiah instead of the usual IDR 1,000,000 a day under Article 78 of the immigration law. It covers visa-free arrivals, who otherwise have no extension available at all. Take your passport, your current permit and written confirmation from your airline or the airport that the flight was cancelled, to any of the nine immigration offices handling them: Soekarno-Hatta is the busiest, with Jakarta Pusat, Jakarta Utara, Jakarta Selatan, Depok, Tangerang, Bekasi, Ngurah Rai and Juanda alongside it. Your airline can lodge the request on your behalf. Nothing is applied automatically, so go before your date passes rather than after.
What about Mount Lewotobi on Flores?
That is a separate volcano, roughly 1,800 kilometres east, and it is also on Alert Level III with a five-kilometre exclusion zone. It fired nine eruptions in seven days in late August and affects the small Flores airports rather than Jakarta. We track it separately in our guide to Mount Lewotobi and Bali travel.

How this page was put together
- The airport list combines two authorities. The Jakarta-area reopening times are the Transport Minister’s own statement of 8 September 2026; the second-wave times are the NOTAM numbers published by AirNav Indonesia, which is the NOTAM authority. Every airport this eruption closed is now open. The ministry counted eight affected; AirNav’s own reopening notice names a ninth field it did not include, Salakanagara at Tanjung Lesung, and this page lists all nine rather than reconciling the two counts silently. The closure windows published on 7 September did not lapse as scheduled: they were extended through Monday. Soekarno-Hatta, Halim Perdanakusuma and Husein Sastranegara then reopened at 00:01 WIB on 8 September, with the first actual movements between 00:30 and 00:42; those are two different things and the board carries the NOTAM time. Budiarto followed at 03:01 and Pondok Cabe at 03:04, Taufik Kiemas at 09:31, Radin Inten II at 09:45 and Salakanagara at 09:50, with Atung Bungsu earlier, at 09:00 on 7 September. Radin Inten II is marked reduced rather than reopened because its own general manager put its first day at ten flights on a single route, with its international service still suspended. The reopening came with two conditions the ministry set: airlines must inspect their fleets, and crews must avoid the marked ash polygons. AirNav says ash is still detectable in the airspace and the second-wave airports remain under monitoring.
- There are no flight fares on this page, deliberately. During an ash closure the sellable inventory on a Jakarta route is neither stable nor representative, so a sampled “from” fare would read as a market price when it is an artefact of the disruption.
- Hotels come from one Wego search of Jakarta plus one eight-kilometre radius search around the Soekarno-Hatta coordinate, both re-sampled on 9 September 2026 for a one-night stay tonight, two adults, one room, in USD. Both searches were run filtered to four stars and a guest score of 8.0 or better, and a floor of at least 200 reviews was then applied on top. That returned 175 unique properties, of which 149 cleared all three. All nine hotels shown yesterday still clear the floor and were still available tonight, so the shortlist is unchanged and only the rates have moved. A card gets replaced when a property drops out, as one did on 8 September, not to churn the list.
- Distances are great-circle from the airport coordinate returned by the Wego places lookup, not driving distance and not a figure quoted from a feed. The zones follow a real gap in the data: nothing clearing the floor sits between 9.7 and 13.1 kilometres.
- Cathay Pacific has stopped publishing anything about this eruption. Its ticketing guideline, whose 5 September terms were publicly readable when this page first went up, now redirects to an agent login in full, and neither its public news pages nor the agent portal’s public index carries a Jakarta item at all. A reader can no longer check the waiver terms independently, which is why this page now sends them to a flight-status lookup rather than quoting terms they cannot verify and can no longer claim under.
- Every visa figure comes from the Directorate General of Immigration’s own pages rather than from a visa agency. The extension eligibility, the limits per arrival type and the three-working-day processing time are from its stay-permit page; the IDR 500,000 charge for a 30-day permit is from its published tariff. Visa exemption is treated as non-extendable because it is absent from that page’s own list of who may extend, which is written as an exhaustive list.
- The IDR 1,000,000 a day overstay charge is set by Article 78 of Law 6 of 2011 and its tariff regulation, not by the immigration fee page, so it is cited to the law. Past 60 days the law replaces the charge with deportation and a re-entry ban.
- The zero-rupiah overstay charge has now been announced for this eruption specifically, which was not true when this page first went up. The Director General of Immigration set it out on 7 September together with an emergency stay permit, the Izin Tinggal Keadaan Terpaksa, for travellers whose flights were cancelled or diverted. The underlying power sits in Article 52 of Ministerial Regulation 9 of 2020 and the Directorate General used the same mechanism for the June 2025 Lewotobi eruption. The permit terms here are taken from the Director General’s own statement as carried by Antara, the state news agency, because the Directorate General’s own press-release index still carries nothing on this eruption. That index has moved since this page first said so, but not onto this: re-checked on 9 September, its latest release was dated 4 September and concerned an unrelated enforcement operation. So the attribution stays with the statement rather than being upgraded to a published release that does not exist. The permit is granted on application and not automatically, and the page says so, because that distinction is what decides whether a reader is fined.
- The refund line is deliberately weaker than the headlines. The Transport Minister said “semua airlines” must facilitate a reschedule or a refund and the civil aviation directorate put it at 100 percent, but both were framed as a request and a public service rather than a decree, and neither cited a regulation. Indonesia’s own passenger-rights instrument, Ministerial Regulation 89 of 2015, is scoped by its title to scheduled carriers in Indonesia. So this page treats the figure as an entitlement on an airline Indonesia licenses and as a lever on one it does not, and points foreign carriers at their conditions of carriage instead. We did not find a decree binding foreign airlines and do not imply one.
- Flight and passenger totals for this episode come from different counting windows and must not be added together. The headline figures here are the Transport Minister’s own, carried by Antara: 2,961 flights disrupted through Monday evening, 2,339 domestic and 622 international, and about 341,000 passengers. They count cancellations, delays and diversions together, not cancellations alone, and they supersede the 1,558 flights and 170,000 passengers this page carried on 7 September. Re-checked on 9 September, no newer ministry figure had been published, so these stand rather than having been quietly refreshed. Separate and narrower counts are quoted where they belong rather than merged into the headline: 108 flights at Bali and 49 at Medan, and 86,760 passengers over 5 to 7 September in the immigration service’s own count. That immigration count is reported as 528 flights, but its own components, 254 arrivals and 266 departures, sum to 520; the discrepancy sits in the source, so this page records it rather than picking a side, and does not use the figure in a headline.
