Flights to Indonesia are resuming after an active volcano on the archipelagic nation erupted, sending plumes of ash more than 11 kilometres into the atmosphere. The Lewotobi Laki-Laki volcano on Flores erupted on Tuesday, throwing air travel in the region into chaos. Dozens of flights to the popular holiday island of Bali, which is about 800 kilometres west of Flores, were cancelled, including two from Perth, with more delayed. Denpasar’s Ngurah Rai International Airport has since released a statement confirming flights had resumed and conditions were expected to remain clear. Aviation expert Ellis Taylor told 9News Perth ash was “terrible” for plane engines to ingest. “It can actually turn into glass and cause the engines to seize,” he said. Taylor urged travellers with Bali plans to contact their airline before setting off to catch their flight.
