Stranded passengers at Adelaide Airport have been told Qantas and Jetstar flights have been cancelled for the entire day.
The public address to passengers advised them to go home because check in would be closed for the rest of the day.
Virgin Blue and regional and international airlines are still flying in and out, because airlines are making different decisions on how to deal with ash from Chile's Puyehue volcano in the local airspace.
Cancellations in and out of Adelaide today left hundreds dtranded due to ash plume.
As Virgin customers checked in smoothly next to growing queues at the Qantas and Jetstar counter space, some Qantas passengers were quietly seething.
Julie Taylor was "furious" about not getting any information about her cancelled flight to Melbourne.
"It absolutely ridiculous, they spend all the booking time trying to get your contact information and then they don't tell you anything," she told AAP.
"Everything I know so far I have heard from word of mouth and on the news."
Qantas spokesman Tom Woodward says the airline regrets the inconvenience and understands passengers' frustration but it won't apologise for putting safety first.
TASSIE TOURISM HIT
Tasmanian businesses, meanwhile, are starting to feel the impact of a third day of cancelled flights.
Jetstar and Tiger Airways are yet to resume services to the state.
The CEO of the Tasmanian Chamber of Commerce and Industry Robert Wallace says businesses trying to send fresh produce interstate and overseas are having to resort to ferry services and chartered flights.
Tourism Council boss Luke Martin says it's lucky it's the middle of winter and cancelled hotel bookings are largely being offset by tourists having to extend their stays.
And Australia Post's warning that some mail deliveries could be affected in coming days.
