Anak Krakatau Eruption Disrupts Jakarta Flights; Indonesia AirAsia Delays, Cancels Services

JAKARTA - Indonesia AirAsia has decided to postpone a number of flights to and from Jakarta following the eruption of Mount Anak Krakatau which is still ongoing in the Sunda Strait, Sunday, September 6, 2026. The delay was carried out because the spread of volcanic ash from the Anak Krakatau Mountain eruption activity is estimated to have an impact on the surrounding airspace and potentially endanger flight safety. Acting President Director of Indonesia AirAsia, Capt. Achmad Sadikin Abdurachman said the airline also made a number of operational adjustments to other flights whose routes could potentially be affected by the spread of volcanic ash. "In connection with this condition, a number of AirAsia flights from and to Jakarta have been canceled or rescheduled. AirAsia has also made a number of operational adjustments to other flights whose flight routes are potentially affected by the spread of volcanic ash," said Achmad in a written statement, Sunday, September 6. Achmad said AirAsia had informed all affected passengers of the change in flight status and the options available to continue their journey. "AirAsia continues to work to help passengers continue their journey safely through the next available flight," he said. Furthermore, Achmad said, the condition of volcanic ash and the activity of Mount Anak Krakatau is still developing. Therefore, passengers traveling to and from the affected areas are asked to check the latest flight status before departure. "AirAsia continues to monitor the development of Mount Anak Krakatau activities and the related airspace conditions, and will provide the latest information on flight operations if there are further changes," said Achmad. Passengers can check flight status through AirAsia's official channel before heading to the airport. The latest information can also be obtained through AirAsia's official account on X @airasia and Instagram @flyairasia, as well as customer service through AskBo.
