Airlines have cancelled further flights departing the island of Bali this morning, citing forecasts of deteriorating flying conditions due to a risk of volcanic ash from the erupting Mount Agung volcano.
A Bali airport spokesman said the airport was still operating normally, but airlines such as Jetstar and Virgin Australia had opted to cancel some flights.
"Bali flying conditions expected to be clear throughout the day, but forecast for tonight has deteriorated so several flights have been cancelled," Australian budget airline Jetstar said.
The erupting volcano had closed the airport for much of this week, stranding thousands of visitors, before winds changed and flights resumed.
Twenty flights were cancelled last night due to concerns over ash.
Some airlines including Malaysia's AirAsia have said they would only operate out of Bali during the day, as the ash could impair visibility at night and wind conditions in the area were unpredictable.
Airlines avoid flying through volcanic ash as it can damage aircraft engines, clogging fuel and cooling systems, hampering pilot visibility and even causing engine failure.
There are also concerns over changing weather conditions with a tropical cyclone south of Java island impacting weather and wind in the area, including for Bali, the Indonesian Meteorological, Climatological and Geophysics agency said.
With some airlines continuing to fly normally this morning, there was frustration among passengers.
Several foreign consulates have set up booths in the international departures area to assist stranded passengers.
