The Brussels airport indicated that the attack resulted in only manual check-in and boarding being feasible, significantly impacting flight schedules.

“On Friday night, 19 September, there was a cyberattack on the service provider for the check-in and boarding systems affecting several European airports, including Brussels Airport,” the airport disclosed in a statement.

However, they’ve deployed backup iPads to counters just in case and are advising customers to check in online beforehand.

Qantas say there’s no impact in Australia.

Virgin Australia has also told 9News its not currently affected by the Collins Aerospace outage.

All affected airports have advised travellers to check their flight status and apologised for any inconvenience.

Formed in 2018, Collins is a US aviation and defense technology company and a subsidiary of RTX Corp., which was formerly Raytheon Technologies.

Collins provides the technology enabling passengers to self-check-in, print boarding passes and bag tags, and handle their own luggage at kiosks.

Collins acknowledged a “cyber-related disruption” to its MUSE (Multi-User System Environment) software at “select airports,” but assured that manual check-in operations remained an option.

“We are actively working to resolve the issue and restore full functionality to our customers as quickly as possible,” it said in a statement.

“The impact is limited to electronic customer check-in and baggage drop and can be mitigated with manual check-in operations.”

The impact was felt only at some airports: the Roissy, Orly and Le Bourget airports in the Paris area reported no disruptions.
