Jakarta’s Skies Clear: Flights Resume After Volcanic Ash Halt

When the sky over Jakarta turned gray on Sunday, it wasn’t a typical smog episode—it was volcanic ash, puffed up by the restless Anak Krakatau volcano just off the coast of Java. The ash plume forced the nation’s busiest airports to shut their doors, leaving travelers stranded and airlines scrambling.

By the first light of Tuesday, September 8, 2026, the situation had eased enough for the Transport Ministry to pull the plug on the closure. Soekarno‑Hatta International, Halim Perdanakusuma, and even Bandung’s Husein Sastranegara Airport threw open their gates just after midnight, while a handful of smaller fields followed suit a few hours later.

Minister Dudy Purwagandhi explained the cautionary approach in a statement: “Wind direction can change in a heartbeat. We needed to be sure the ash had cleared before letting planes take off again.” His team ran tests at every runway, taxiway and aircraft‑parking spot. The good news? No detectable ash lingered on the surfaces, but a thorough cleaning was still ordered to erase any lingering grit that could damage engines.

While the main hubs were back online, three airports—most notably Radin Inten II in Lampung, perched on Sumatra’s southern tip—remained closed until mid‑morning. The decision reflected the volatile nature of the ash cloud, which can linger in low‑lying areas even after the main plume disperses.

The eruption itself was a show of raw power: lava fountains, thunderous booms and ash columns that shot sky‑high. Although the dramatic activity died down by Sunday night, the volcano stayed on alert, with minor eruptions logged at 5:08 a.m. and 5:34 a.m. on Tuesday. The height of those ash columns wasn’t measured, but officials said they were far less threatening than the earlier bursts.

In total, the shutdown scrambled nearly 2,961 scheduled flights—about 622 of them international. Passengers at Bali’s Ngurah Rai airport, for example, watched hours of delays roll by, some taking shelter in the terminal while crews re‑routed planes.

Now, with the skies clearing, airlines are slowly re‑establishing their timetables. “We’re working with the airports to prioritize urgent cargo and passenger flights,” Purwagandhi added, hinting that the full schedule might not be back for a couple of days.

For travelers, the lesson is clear: keep an eye on volcanic activity reports when heading to Indonesia’s islands. Nature’s mood swings can ground even the most sophisticated air networks, but the resilience of Indonesia’s aviation sector shows it can bounce back—sometimes within the same night.
