Volcanic Ash Cloud Grounds Flights at Indonesia's Main Airport 2026

Volcanic ash from Anak Krakatoa forced the suspension of operations at Indonesia's main international airport, Soekarno-Hatta, grounding flights and affecting thousands of passengers.

The Anak Krakatoa volcano, located in the Sunda Strait between Java and Sumatra, erupted on Saturday, producing lava and booming sounds heard up to 700 kilometers away. Two more eruptions on Sunday prompted authorities to extend the shutdown until at least 1:30 PM local time.

Impact on Flights and Passengers

More than 22,000 passengers and 209 flights were disrupted, with major routes to Singapore, Doha, Sydney, and Kuala Lumpur affected. At least 16 domestic flights to Bali were also canceled, according to local airport authorities.

The transport ministry confirmed that a paper test showed positive results for volcanic ash spread in the airport area, necessitating the closure to ensure safety.

Why Volcanic Ash Is Dangerous for Aircraft

Volcanic ash can severely damage jet engines by baking onto hot internal parts, wearing out turbine blades quickly, and clogging fuel and air systems. It can also impair pilots' visibility by damaging windscreens.

How Airlines and Passengers Are Responding

Airlines are working to rebook passengers on alternative flights, but the uncertainty of the volcano's activity complicates scheduling. Passengers are advised to check with their airlines for updates and consider flexible travel options.

Authorities continue to monitor Anak Krakatoa's activity and will reopen the airport only when it is safe for operations.

Key Takeaways for Travelers

• Check flight status regularly before heading to the airport.
• Contact your airline for rebooking or refund options.
• Consider travel insurance that covers natural disasters.
• Stay updated on volcanic activity warnings from official sources.
