The airport on Indonesia's holiday island of Bali reopened on Friday,29 June, after ash from a volcano forced a brief closure and the cancellation of more than 300 flights.
Mount Agung in northeastern Bali has been rumbling to life intermittently since late 2017 and it began belching smoke and ash again on Thursday.
Agung towers over eastern Bali to a height of just over 3,000 metres (9,800 feet). Its last major eruption in 1963 killed more than 1,000 people and razed several villages.
It was shooting a column of ash more than 2,500 metres (8,200 feet) into the sky on Friday, and officials said operations at Indonesia's second-busiest airport would be reviewed every few hours.
Earlier, authorities were forced to cancel 115 international flights and 203 domestic ones, affecting nearly 27,000 travellers.
"We’re monitoring the eruption. The airport could be closed again if the eruption affects flight safety." - Israwadi, a spokesman for airport operator Angkasa Pura
Airlines avoid flying through volcanic ash as it can damage aircraft engines, clog fuel and cooling systems and hamper visibility.
Sutopo Purwo Nugroho of the disaster mitigation agency said activity was going on deep under the volcano.
“Micro tremors are still being detected... indicating that magma is moving towards the surface,” Nugroho said in a statement.
Operations at Bali Airport Disrupted in December
Operations at Bali's airport were disrupted for more than week in early December, stranding thousands of visitors before winds changed to blow the smoke away and the volcano calmed down.
Hundreds of villagers living near the volcano evacuated their homes as it began erupting on Thursday, and moved into three evacuation centres.
Anxious passengers thronged Bali's airport, waiting for news about their flights.
Among the airlines serving the resort island, Garuda Indonesia, Sriwijaya and Indonesia Air Asia said they were working to help stranded passengers.
Virgin Australia, Qantas and Jet Star were monitoring the situation in consultation with Australia's Bureau of Meteorology's Volcanic Ash Advisory Centre.
