Bali ash snarls flights

Volcanic ash from Mount Lewotobi Laki-Laki disrupted flights to and from Bali on April 12, forcing airlines to cancel, delay or reroute service. (thetraveler.org) Reports published April 12 tied the ash event to about 46 cancellations and roughly 600 delays across airports including Jakarta, Bali, Shanghai, Bangkok, Narita, Yancheng and Mumbai. Airlines changed routes to avoid contaminated airspace around eastern Indonesia. (travelandtourworld.com) Mount Lewotobi Laki-Laki sits on Flores, east of Bali, and it has stayed active into 2026 with repeated ash emissions in late March and early April. The Smithsonian Institution’s Global Volcanism Program logged continuing activity during March 26 to April 1, including ash plumes and daily emissions. (volcano.si.edu) Ash matters to aviation because it can sandblast cockpit windows, clog sensors and melt inside jet engines. Australia’s Bureau of Meteorology says volcanic ash advisories are issued for flight planning, and Darwin is the advisory center covering this region. (bom.gov.au) On April 12, a Darwin Volcanic Ash Advisory reported ash from Lewotobi observed to flight level 070, or about 7,000 feet, moving northwest. That direction matters because winds, not just the eruption itself, determine whether Bali routes are affected. (volcanodiscovery.com) By April 13, the Bureau of Meteorology page showed no current volcanic ash advisories from Darwin in the previous 24 hours. That does not erase the April 12 disruption, but it suggests the immediate ash warning had eased by Monday. (bom.gov.au) Bali is used to this kind of stop-start disruption because the island’s main airport can be open while ash farther east still scrambles approach paths and regional feeder routes. The Traveler reported that shifting wind directions and ash corridors were driving the latest round of schedule changes. (thetraveler.org) This is not the first time Lewotobi has hit Bali-bound travel. In June 2025, Bali airport said 24 arrivals and departures were canceled after a larger Lewotobi eruption, showing how a volcano on Flores can ripple across Indonesia’s tourism hub. (en.antaranews.com) For travelers, the practical issue is timing: ash clouds can shift faster than airport operations on the ground. On April 13, the ash warning had eased, but airlines and airports were still left to work through the cancellations, delays and rebookings triggered a day earlier. (bom.gov.au)
