Bali flights halted by ash

Volcanic ash from Mount Lewotobi has forced another round of flight cancellations around Bali, leaving travelers stranded as airlines reroute or scrub services into Ngurah Rai airport. (thetraveler.org) The renewed disruption was reported on April 12, 2026, after ash from the volcano on Flores drifted into air corridors used by Bali-bound flights. Coverage described cancellations, diversions and delays on both domestic and international routes over the previous two days. (thetraveler.org) Mount Lewotobi Laki-Laki sits in East Flores, several hundred kilometers east of Bali, but ash can spread far beyond the crater and threaten jet engines and cockpit visibility. Indonesia’s weather agency, Badan Meteorologi, Klimatologi, dan Geofisika, said in a previous Lewotobi episode that ash was tracked at up to 10,000 feet and moving with steady intensity. (antaranews.com) Bali’s airport has been through this before. On March 21, 2025, Ngurah Rai airport said seven international flights were canceled because of Lewotobi ash, most of them on Australia-Bali routes. (antaranews.com) The disruption grew much larger in June and July 2025. Indonesian and regional reports said Lewotobi sent ash as high as 10 kilometers on June 17 and 18 kilometers on July 7, with Bali airport recording 25 canceled flights in June and 24 more cancellations in July before some services recovered. (antaranews.com) (mediaindonesia.com) (antaranews.com) Airport managers and airlines usually do not wait for ash to settle over the runway before acting. During earlier Lewotobi disruptions, Bali airport said it used runway checks and “paper tests” to detect ash, while carriers offered refunds, rebooking or rerouting for affected passengers. (liputan6.com) (antaranews.com) The wider pressure point is Bali’s role as Indonesia’s busiest tourism gateway. Airport operator data has previously identified I Gusti Ngurah Rai as the busiest airport in its network, so even a short ash event can cascade into packed terminals, missed connections and aircraft out of position. (ppid.ap1.co.id) Officials have also had to plan around the possibility that air travel stops entirely in eastern Indonesia. During the July 2025 eruption, the Transportation Ministry said it was preparing emergency sea transport for travelers who could not fly because of Lewotobi. (antaranews.com) For passengers in Bali now, the practical reality is the same as in the earlier ash waves: flights can return in clusters once conditions clear, but schedules can change by the hour while airlines and airport staff wait for the ash to move out of the flight path.
