Thick fog has forced cancellations and delays at Perth Airport overnight, adding to the confusion caused by Friday’s eruption of Sangeang Api volcano.
Four Tigerair domestic flights have been cancelled and 10 international flights delayed because of the thick fog which blanketed the city.
A Perth Airport spokeswoman said skies cleared and normal scheduling resumed about 5.30am, but the effects were still being felt.
Delayed flights this morning include a 7.10am Cathay Pacific flight to Hong Kong, a 7.20am Garuda Indonesia flight to Denpasar, an 8.10am Jet Asia flight to Singapore and a 9.15am Thai Airways flight to Bangkok.
Meanwhile, Jetstar has cancelled five flights between Perth and Bali today as ash from the volcano on the Indonesian island of Sumbawa continues to spread
Other airlines are continuing to fly to Bali.
It is not clear whether Jetstar will cancel its 1.35pm service to Denpasar.
Flights to and from Darwin resumed yesterday but doubts remained over flights to Denpasar airport as the south-westerly ash cloud moved towards Bali.
Jetstar cancelled the 8.15pm flight JQ122 from Perth to Denpasar and the return flight today, flight JQ121, was also cancelled.
All flights to and from Bali and Adelaide, Melbourne and Sydney last night and today were also cancelled by the airline.
But Virgin and Air Asia flights were still scheduled to fly to Denpasar last night.
Darwin was cut off to all air services on Saturday as ash plumes billowed from the volcano.
It erupted continuously from Friday afternoon.
The major plume affecting Australian aviation swept south-east over the west side of the Northern Territory and as far south as Alice Springs.
The volcano sent ash 20km into the sky and the cloud drifted south over northern Australia.
All flights through Darwin were cancelled on Saturday and Virgin Australia cancelled its Saturday night flights to and from Bali.
