Singapore Airlines and AirAsia Cancel Jakarta Flights After Mount Anak Krakatau Eruption 2026

Volcanic activity at Mount Anak Krakatau has paralyzed key air corridors between Singapore and Indonesia, forcing major carriers to scrap dozens of flights to ensure passenger safety.

The eruption of Mount Anak Krakatau on 6 September 2026 has triggered immediate operational shutdowns across Southeast Asian airspace. Volcanic ash clouds, which pose a lethal threat to jet engines, have forced Singapore Airlines and AirAsia to issue urgent travel advisories and cancel numerous services to and from Jakarta’s Soekarno-Hatta International Airport.

Singapore Airlines Suspends Key Jakarta Rotations

Singapore Airlines acted swiftly to mitigate aviation risks, canceling a significant portion of its daily frequency between Singapore Changi Airport and Jakarta. The disruption spanned the entire operational day, impacting morning, afternoon, and evening departures.

The following specific services were canceled on 6 September 2026:

Flight Number	Route	Scheduled Departure
SQ950	Singapore $\rightarrow$ Jakarta	0620hrs
SQ952	Singapore $\rightarrow$ Jakarta	0740hrs
SQ956	Singapore $\rightarrow$ Jakarta	0905hrs
SQ953	Jakarta $\rightarrow$ Singapore	0805hrs
SQ955	Jakarta $\rightarrow$ Singapore	0925hrs
SQ957	Jakarta $\rightarrow$ Singapore	1100hrs
SQ958	Singapore $\rightarrow$ Jakarta	1235hrs
SQ960	Singapore $\rightarrow$ Jakarta	1510hrs
SQ962	Singapore $\rightarrow$ Jakarta	1615hrs
SQ964	Singapore $\rightarrow$ Jakarta	1720hrs
SQ966	Singapore $\rightarrow$ Jakarta	1830hrs
SQ965	Jakarta $\rightarrow$ Singapore	1920hrs
SQ967	Jakarta $\rightarrow$ Singapore	2015hrs

The carrier warned that additional flights may be adjusted as volcanic conditions remain volatile. Passengers are urged to maintain updated contact details for rebooking and refund notifications.

AirAsia and Regional Carriers Face Network Pressure

AirAsia has mirrored these precautions, implementing widespread cancellations and rescheduling for its Jakarta operations. As a low-cost carrier with a dense regional network, AirAsia's disruptions highlight how volcanic events create a "domino effect" across Southeast Asian connectivity.

Beyond the two major carriers, other airlines including Garuda Indonesia, Batik Air, and Citilink have been forced to adjust their schedules. Because aircraft rotations and crew assignments are tightly linked, a single delay at Jakarta airport often disrupts subsequent flights to entirely different destinations.

Soekarno-Hatta International Airport Operations

Jakarta’s primary gateway, Soekarno-Hatta International Airport, experienced temporary suspension of all flight operations after ash was detected in the immediate airspace. Airport operator Angkasa Pura confirmed that hundreds of movements were affected.

While the Singapore corridor saw the highest volume of cancellations, the disruption extended to several global hubs, including:

• Kuala Lumpur
• Hong Kong
• Sydney
• Seoul
• Doha
• Amsterdam

The Technical Danger of Volcanic Ash

The rapid response from aviation authorities is driven by the specific physical properties of volcanic ash. Unlike organic clouds or fog, volcanic ash consists of jagged particles of rock and glass.

When these particles enter a jet engine, they can melt at high temperatures and solidify on the turbine blades, potentially leading to total engine failure. Furthermore, ash clouds:

• Obscure pilot visibility during critical flight phases.
• Damage sensitive aircraft sensors and external fuselage surfaces.
• Interfere with navigation systems.
• Create hazardous conditions for take-off and landing.

Monitoring agencies detected ash clouds at varying altitudes, reaching 20,000 feet over Java and peaking at 50,000 feet over portions of Sumatra.

Regional Impact and Safety Monitoring

Mount Anak Krakatau, situated in the Sunda Strait between Java and Sumatra, is a high-risk zone. It is the successor to the historic Krakatau volcano, known for its catastrophic 1883 eruption.

Current ash movement has been tracked across Banten, West Java, Lampung, and the Jakarta metropolitan area. While no casualties have been reported, authorities continue to monitor the volcano's activity to determine when it is safe to resume full flight schedules.

Passenger Guidance for Affected Travelers

Travelers operating within the Indonesia-Singapore corridor are advised to take the following steps:

• Verify Status: Check real-time flight status via airline apps before departing for the airport.
• Update Profiles: Ensure mobile numbers and email addresses are current in booking records.
• Booking Channels: Those who booked via third-party agents should contact the agent directly for refunds, while direct bookings should use official airline channels.
• Buffer Time: Allow significant extra time for travel due to anticipated schedule volatility.

The resumption of normal air traffic in the region remains entirely dependent on the stabilization of Mount Anak Krakatau and the dissipation of ash clouds.

Key Takeaways

• Major Cancellations: Singapore Airlines and AirAsia have canceled numerous flights to/from Jakarta on 6 September 2026.
• Hub Disruption: Soekarno-Hatta International Airport saw temporary closures affecting routes to Singapore, Seoul, Sydney, and Amsterdam.
• Aviation Risk: Volcanic ash at altitudes up to 50,000 feet poses a critical threat to jet engine integrity and visibility.
• Network Effect: Delays in Jakarta are creating operational bottlenecks for regional carriers like Garuda Indonesia and Batik Air.

FAQ

Why can't planes fly through volcanic ash? Volcanic ash is composed of glass and rock particles that can melt inside jet engines, causing them to fail. It also damages sensors and reduces visibility.

Which airlines are most affected? Singapore Airlines and AirAsia have issued the most detailed advisories, though Garuda Indonesia, Batik Air, and Citilink are also experiencing disruptions.

How do I get a refund for my canceled Jakarta flight? Passengers who booked directly should use the airline's official assistance channels. Those who used travel agents must contact their provider for rebooking or refunds.
