Anak Krakatau Ash Cloud Grounds Jakarta Flights, Strands Travelers
Ash from the ongoing eruption of Anak Krakatau has brought flight operations at Jakarta's Soekarno-Hatta International Airport to a near standstill, severing direct air connections between South Korea and Indonesia and leaving tourists, corporate travelers, and Indonesian residents in limbo.
What happened and when
The eruption began on September 4, 2026, and ash spread across the Jakarta metropolitan area within days. By September 7, local transport authorities reported that at least 209 flights, covering both domestic and international routes, had been directly or indirectly affected. Takeoffs and landings at Soekarno-Hatta were completely halted at the height of the disruption.
Four carriers operating the Seoul Incheon to Jakarta corridor, Korean Air, Asiana Airlines, T'way Air, and Garuda Indonesia, all grounded their services on September 6. Korean Air had already delayed its round-trip service on September 5 by approximately 13 hours and 20 minutes before ultimately canceling it, then canceled all subsequent departures the following day. Seoul Economic Daily, which first reported these details, noted that Asiana Airlines indicated irregular operations on its Jakarta route were expected to continue at least until 11:59 p.m. Korean time on September 7.
Refunds, rebooking, and what passengers need to know
Airlines have introduced emergency flexibility policies, though with important caveats. T'way Air announced it would fully waive refund and rebooking fees for flights confirmed as officially canceled. However, passengers who proactively cancel before an official cancellation announcement are still liable for standard fees, even if the flight is later canceled. Travelers who booked through third-party agencies must process any changes through those agencies rather than directly with the airline.
Korean Air and Asiana Airlines are applying their respective natural disaster policies to assist affected passengers with rebooking and schedule changes. South Korea's Ministry of Foreign Affairs also posted a travel advisory on September 6, urging Korean nationals in Indonesia to exercise heightened caution.
Ripple effects beyond the airport
The disruption reaches well beyond grounded planes. Jakarta functions as the primary gateway for onward domestic connections across the Indonesian archipelago, meaning passengers bound for regional destinations face compounding delays. Observers cited by Seoul Economic Daily noted that a prolonged closure could affect local accommodation, ground transportation, and business schedules across the city. The timeline for a return to normal operations remained unclear as of September 7, with ash continuing to spread.
Why it matters for hosts
Independent accommodation and hospitality operators in Jakarta and nearby destinations should prepare for an extended period of irregular arrivals and last-minute cancellations. Proactively communicating your cancellation and rescheduling policy to guests with upcoming bookings reduces disputes and builds goodwill during a situation outside anyone's control. If your property relies heavily on international arrivals, this is also a good moment to review your force-majeure clauses and ensure your listing reflects any temporary operational changes. Guests who do make it through will likely arrive exhausted after long delays, so a clear, calm check-in process will matter more than usual.
