Singapore Airlines Pairs Up With AirAsia And More Airlines Across Asia As Indonesia Volcano Eruption Raises Travel Concerns

Eruption of Mount Anak Krakatau causes travel chaos in Indonesia as Singapore Airlines and AirAsia release travel alerts. Eruption of Mount Anak Krakatau in Indonesia has resulted in travel disruptions in the region as airlines like Singapore Airlines and AirAsia have issued travel alerts, canceled some of their flights and changed their flight schedule amid volcanic ash cloud that has raised safety issues in Southeast Asia airspace. The eruption has affected the flights at Jakarta’s Soekarno Hatta International Airport.

The volcanic event placed Singapore–Indonesia air connectivity under pressure on 6 September 2026, with airlines prioritising passenger safety while monitoring changing ash conditions. Singapore Airlines cancelled multiple Jakarta services, while AirAsia announced cancellations and schedule adjustments for flights operating to and from Jakarta.

Singapore Airlines Cancels Jakarta Flights As Volcanic Ash Creates Aviation Risk

Singapore Airlines became one of the first major international carriers to issue a detailed advisory after Mount Anak Krakatau’s eruption affected flight operations.

The airline cancelled multiple flights between Singapore Changi Airport and Jakarta Soekarno-Hatta International Airport on 6 September 2026 due to volcanic activity and the presence of ash clouds in the region.

The affected services included flights operating throughout the day, covering morning, afternoon and evening departures between the two major Southeast Asian aviation hubs.

The cancelled Singapore Airlines services included:

• SQ950 Singapore–Jakarta departing at 0620hrs
• SQ952 Singapore–Jakarta departing at 0740hrs
• SQ956 Singapore–Jakarta departing at 0905hrs
• SQ953 Jakarta–Singapore departing at 0805hrs
• SQ955 Jakarta–Singapore departing at 0925hrs
• SQ957 Jakarta–Singapore departing at 1100hrs
• SQ958 Singapore–Jakarta departing at 1235hrs
• SQ960 Singapore–Jakarta departing at 1510hrs
• SQ962 Singapore–Jakarta departing at 1615hrs
• SQ964 Singapore–Jakarta departing at 1720hrs
• SQ966 Singapore–Jakarta departing at 1830hrs
• SQ965 Jakarta–Singapore departing at 1920hrs
• SQ967 Jakarta–Singapore departing at 2015hrs

Additional adjusted services were also listed by the airline as the situation developed.

Singapore Airlines warned passengers that other flights between Singapore and Indonesia could also be affected because volcanic conditions remained unpredictable. Customers were advised to check updated flight information, maintain updated contact details and use official assistance channels for rebooking or refunds.

AirAsia Joins Travel Advisory As Jakarta Flights Face Cancellations And Rescheduling

AirAsia also issued a travel advisory after the continuing eruption of Mount Anak Krakatau generated extensive volcanic ash clouds over the region.

The airline confirmed that flights to and from Jakarta were cancelled or rescheduled due to the potential threat volcanic ash poses to aircraft operations. AirAsia stated that volcanic ash near flight paths can create significant safety risks, requiring airlines to make operational changes.

Affected AirAsia passengers were informed about their flight status and available recovery options. The airline advised travellers flying to or from affected destinations to check their latest schedules before arriving at the airport.

The disruption demonstrated the wider impact of volcanic activity on low-cost carriers, which operate large regional networks connecting major Southeast Asian cities.

Jakarta Airport Operations Disrupted As Volcanic Ash Spreads Across Indonesia

The eruption caused major disruption at Soekarno-Hatta International Airport, Indonesia’s busiest aviation gateway.

Authorities temporarily suspended flight operations after volcanic ash was detected around the airport’s airspace. The closure affected domestic and international services, creating delays and cancellations for thousands of travellers.

Airport operator Angkasa Pura reported that the disruption affected hundreds of flight movements, including international services connecting Jakarta with major destinations across Asia and beyond.

International routes affected included connections involving:

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

Singapore was among the most affected international markets because of the high frequency of daily flights between Jakarta and Changi Airport.

Volcanic Ash Clouds Create Serious Challenges For Aircraft Safety

The main reason airlines reacted quickly was the danger created by volcanic ash.

Unlike normal weather disruptions, volcanic ash can create direct risks to aircraft systems. Fine ash particles can enter jet engines, melt at high temperatures and potentially damage engine components.

Volcanic ash can also:

• Reduce visibility during flight operations
• Damage aircraft sensors and external surfaces
• Affect navigation systems
• Create unsafe conditions during take-off and landing

Authorities detected ash clouds reaching different altitudes, including around 20,000 feet over Java and up to 50,000 feet over parts of Sumatra, increasing concerns for aircraft operating in surrounding airspace.

More Asian Airlines Monitor Operations As Indonesia’s Aviation Network Feels Pressure

The impact was not limited to Singapore Airlines and AirAsia.

Other airlines operating through Jakarta were also affected as airport restrictions and volcanic ash assessments continued.

Carriers including Batik Air, Citilink and Garuda Indonesia faced operational adjustments linked to Jakarta airport disruption. International airlines operating Jakarta routes also monitored conditions before continuing normal schedules.

The disruption created a chain effect across airline networks because aircraft rotations, crew schedules and connecting flights depend on airport availability.

A delayed aircraft arriving into Jakarta can affect later departures to other destinations, creating wider operational challenges beyond the initial volcanic event.

Indonesia Monitors Mount Anak Krakatau As Authorities Focus On Safety

Mount Anak Krakatau is located in the Sunda Strait between Java and Sumatra and remains one of Indonesia’s most closely monitored volcanoes.

The volcano is the successor of the historic Krakatau volcano, whose 1883 eruption became one of the most powerful volcanic events recorded in history.

Authorities confirmed that the latest eruption caused ash movement across parts of western Indonesia, including areas around Jakarta, Banten, West Java and Lampung.

Although no major casualties were reported, authorities advised communities and visitors to remain cautious around the volcano area. Monitoring agencies continued assessing volcanic activity, ash movement and aviation conditions.

Travel Advice For Passengers Flying Between Singapore And Indonesia

Travellers affected by the Mount Anak Krakatau disruption were advised to:

• Check airline flight status before travelling
• Keep mobile numbers and booking information updated
• Follow airline notifications
• Contact airlines directly for rebooking options
• Allow extra time for possible schedule changes

Singapore Airlines advised customers who booked directly with the airline to use official assistance channels for rebooking or refund requests. Passengers who booked through travel agents or partner airlines were advised to contact those providers directly.

AirAsia similarly encouraged passengers to check updated flight information as the airline continued monitoring volcanic conditions.

Southeast Asia Aviation Faces Another Volcanic Challenge

The Mount Anak Krakatau eruption highlights the vulnerability of Southeast Asia’s aviation network to natural events.

With Singapore, Indonesia and Malaysia serving as major regional travel hubs, volcanic disruptions can quickly affect tourism, business travel and international connections.

For travellers, the latest incident reinforces the importance of checking real-time airline updates before departure, especially when travelling through destinations located near active volcanic zones.

Eruption of Mount Anak Krakatoa hampers flights in Indonesia with Singapore Airlines, Air Asia and other airlines issuing advisories.

With the airlines continuously watching the situation, the resumption of normal operations will hinge on the volcano and ash movement.
