Mount Anak Krakatau erupted late Friday, sending volcanic ash across Jakarta and forcing eight Indonesian airports to shut down. Nearly 3,000 flights were disrupted and more than 340,000 passengers were left stranded for two days. Jakarta’s Soekarno-Hatta International Airport, the busiest hub, did not resume operations until 00:30 Tuesday. The closure affects Australian travellers and airlines operating regional routes.
How the eruption unfolded
Anak Krakatau, located in the Sunda Strait between Java and Sumatra, began erupting late Friday with lava fountains and ash clouds. Volcanic ash reached 20,000 feet on the Java side and 50,000 feet on the Sumatra side. The volcano remained seismically active throughout the weekend, forcing authorities to extend airport closures repeatedly.
Scale of flight disruptions
Nearly 3,000 flights were disrupted across the eight affected airports, with 964 flights cancelled at Jakarta’s main airport alone. More than 340,000 passengers were stranded. Singapore Airlines, Malaysia Airlines, AirAsia and Lion Air Group cancelled flights to and from Jakarta. At the initial closure, the airport suspended operations until 11:59 p.m. Sunday, but extended the suspension several times before reopening Tuesday at 00:30.
Passenger chaos and alternative transport
Snaking queues formed at departure halls as stranded passengers sought refunds and flight updates. One passenger, Finna, spent the night on two intercity trains to reach Jakarta on Monday rather than wait at the airport. Passengers reported poor communication from airlines, with some not notified of cancellations until arriving at the terminal. Conservation worker Jo Shaw’s team cancelled plans to camp at Java’s Ujung Kulon National Park after authorities raised the volcano alert level.
Travel insurance and claims
Travel Insurance Direct and AllClear Travel advised customers that policies purchased before the eruption may cover losses, but those bought after the event became known will not. Affected travellers must retain all documentation of expenses and contact airlines first to change arrangements. Australian travellers are urged to check the DFAT Smart Traveller website for the latest advice.
Final Thoughts
The two-day airport closure disrupted regional aviation and stranded hundreds of thousands of passengers. Australian travellers should verify travel insurance coverage and monitor official alerts before booking to or through Indonesia.
