There was widespread air travel disruption across Indonesia and parts of Southeast Asia, due to continued volcanic activity of Mount Anak Krakatau. This caused volcanic ash to enter airspace. As a safety measure Soekarno-Hatta International Airport in Jakarta was closed. This forced AirAsia to cancel over 100 flights planned for 6 and 7 September 2026.

The disruption affected domestic connections between Jakarta and popular Indonesian destinations, including Bali, Labuan Bajo, Silangit and Bandar Lampung. International routes linking the Indonesian capital with Malaysia, Cambodia and Brunei were also interrupted.

Passengers travelling through Jakarta were advised to check their flight status before leaving for the airport, as volcanic activity and shifting wind conditions could continue to influence airline operations.

Volcanic ash forces major safety response around Jakarta

Mount Anak Krakatau’s continuing eruption produced extensive volcanic ash clouds over the Sunda Strait. Depending on their altitude and direction, these clouds can spread into airspace used by commercial aircraft arriving at or departing from Jakarta.

Volcanic ash represents a serious aviation hazard. Unlike normal clouds, ash contains small particles of rock, minerals and volcanic glass. These materials can damage aircraft windscreens, reduce visibility and affect navigation equipment.

Ash can also enter jet engines, where extreme temperatures may cause it to melt. The material can then accumulate inside the engine, restricting airflow and potentially causing a loss of power. Airlines therefore avoid operating through confirmed or suspected volcanic ash clouds, even when conditions appear manageable from the ground.

The temporary closure of Jakarta’s principal international airport was introduced as a precaution while aviation and volcanic authorities assessed the developing situation.

Jakarta airport closure affects domestic and international services

The operational restrictions at Soekarno-Hatta International Airport had consequences far beyond Jakarta. As Indonesia’s leading aviation gateway, the airport supports a dense network of domestic and international routes.

AirAsia cancelled or rescheduled all affected services operating to and from Jakarta. Additional adjustments were made to selected flights whose planned paths could have brought them close to the volcanic ash.

The disruption reached several important tourism and business markets. Services between Jakarta and Denpasar Bali represented a large share of the cancellations. Flights connecting the capital with Kuala Lumpur, Penang, Johor Bahru, Kuching, Kota Kinabalu and Kota Bharu were also affected.

Other interrupted routes included links with Phnom Penh, Brunei, Labuan Bajo, Silangit and Bandar Lampung.

The scale of the cancellation programme demonstrated how disruption at one major hub can quickly spread across a regional airline network. Aircraft and crews scheduled to arrive in Jakarta may be required for later services, meaning one cancellation can affect several subsequent departures.

What options are available to affected AirAsia passengers?

Passengers whose flights were cancelled or significantly disrupted were notified through the contact details attached to their reservations. AirAsia introduced four service-recovery choices to help travellers rearrange their journeys.

Full refund

Affected passengers can request a full refund. The money will be returned through the original payment method used to purchase the booking.

Processing times may differ depending on the bank, card provider or payment platform involved.

AirAsia credit account

Passengers can choose to receive the value of their affected booking as credit in their AirAsia member account.

The credit remains valid for 730 days from its issuance date, providing travellers with additional time to arrange another journey within the airline’s network.

One-time flight change

Eligible passengers can move their journey to another date without paying a flight-change fee.

The replacement service must operate on the same route and depart within 30 days of the original travel date. This option remains subject to seat availability.

Rerouting within Indonesia

Passengers may also request a new itinerary to one of the selected Indonesian destinations served by AirAsia.

The alternative journey must take place within 30 days of the original booking and is subject to available seats.

Travellers should review the conditions attached to each option before selecting one. Once a refund, credit or replacement booking has been processed, changing to another recovery choice may not always be possible.

Bali and Kuala Lumpur routes face extensive interruption

The Jakarta–Bali corridor experienced some of the most significant disruption. Multiple services in both directions were cancelled across the two affected days, including flights QZ802, QZ803, QZ806, QZ807, QZ808, QZ809, QZ814, QZ815, QZ818, QZ819, QZ820 and QZ821.

These cancellations affected one of Indonesia’s most important domestic tourism links. Jakarta acts as a principal entry point for international passengers continuing to Bali, while the route also serves business travellers, residents and tourists moving between the two cities.

Connections between Jakarta and Kuala Lumpur were similarly affected. Several Indonesia AirAsia and AirAsia Malaysia services were withdrawn, limiting one of the busiest international links in the carriers’ regional networks.

The consequences were also felt on routes that did not directly connect with Jakarta. Flights between Kuala Lumpur and Palembang were included in the 7 September cancellation programme, illustrating how aircraft positioning and wider airspace considerations influenced operations elsewhere.

Travellers urged to check updates before reaching airports

Passengers with upcoming AirAsia bookings should verify their departure status through the airline’s official digital channels before travelling to an airport. Flight information displayed when a passenger first receives a disruption alert may change if volcanic activity intensifies or airspace restrictions are revised.

Customers should also ensure that the telephone number and email address included in their reservation remain accurate. Airlines normally use these details to distribute cancellation notices, rebooking instructions and operational updates.

Travellers with connecting flights, hotel reservations or pre-booked transfers should contact the relevant providers as soon as possible. Travel insurance policies may cover some additional costs, although coverage will depend on the policy wording and the circumstances surrounding the volcanic eruption.

Passengers who booked through a travel agent may need to process refunds or itinerary changes through that agency rather than directly with the airline.

Resumption depends on volcanic and airspace assessments

A return to normal service will depend on the direction, density and altitude of the volcanic ash cloud, along with official assessments of airport and regional airspace conditions.

An airport reopening does not necessarily mean that every cancelled flight can operate immediately. Airlines must reposition aircraft, restore crew schedules and accommodate passengers displaced by earlier cancellations. Seat availability on the first services after reopening may therefore remain limited.

AirAsia is continuing to monitor Anak Krakatau and the surrounding airspace. Further travel advisories are expected as conditions develop and normal operations are gradually restored.

For affected passengers, safety remains the central reason behind the disruption. Volcanic ash can be difficult to detect visually and may travel far beyond the eruption site. Cancelling or rescheduling services allows aircraft to remain outside hazardous areas until aviation authorities determine that flights can resume safely.
