'Chaos': Flights grounded as software outage affects millions

Frustrated travellers have been left facing delays around the country on Friday afternoon, with many reporting being stranded at airports and huge wait times due to the systems being down. In the US, entire airlines have grounded their fleets.

Cybersecurity software Crowdstrike caused computers around the world to shut down at around 2.30pm AEST, impacting airlines, banks, supermarkets, media outlets and more.

The issue stems from a “bluescreen error” as a result of the outage, with servers and devices getting stuck in “boot loops”.

Confused passengers have taken to social media to vent their frustrations about the outrage impacting their travel plans.

“The major tech outage is also hitting Sydney airport,” one wrote on X, formerly Twitter.

“Apparently @JetstarAirwways says it cannot check in or board passengers.

“There is also a complete ground stop, with @VirginAustralia telling passengers that there are ‘no flights in or out’ due to the outrage.”

“This is causing chaos at the airport,” another said.

“Melbourne is chaotic and passengers are unable to get checked in.”

“I’m at Brisbane airport and Virgin seems to be down,” one wrote.

“None of the screens at Sydney airport are working,” another shared.

A Virgin Australia spokeswoman told news.com.au that they were aware of the issue having an impact on flights.

"Virgin Australia operations are continuing following a large-scale IT outage impacting multiple airlines and other businesses, however some cancellations and delays are expected," she said.

"We are working to resolve any delays and get our guests on their way as quickly as possible."

News.com.au understands that Qantas and Jetstar are also experiencing impacts to their systems due to the outrage. 

Sydney Airport said in a statement on X, formerly Twitter, that there would be delays throughout the evening.

“A global technical outage has impacted some airline operations and terminal services,” a spokesperson said.

“Flights are currently arriving and departing however there may be some delays throughout the evening.

“We have activated our contingency plans and deployed additional staff to our terminals.

“If you're travelling today make sure you leave plenty of time to come to the airport and check with your airline regarding the status of your flight.”

Melbourne, Brisbane and Perth Perth airports also shared similar statements.

Passengers in other airports across the world have reported huge delays and chaotic scenes due to system outrages.

In the US, all flights from several major airlines have been grounded. Delta, United and American have all been ordered to ground flights by the Federal Aviation Administration.

Other US low cost carriers including Frontier have also been impacted.
