Passengers at Copenhagen (Københavns) and Billund Airports are experiencing IT problems, leading to the necessity of manual check-ins. Julie Pi Boll, press officer at Copenhagen Airport, has stated that operations are currently normal, but some airlines are struggling with IT system difficulties, thus prolonging the check-in process.
At 11:30, TV 2 reported that the situation remains the same, with delays due to issues in several destination airports. Passengers are advised to stay updated on their flight departures.
Similar problems are also being faced at Billund Airport, where senior manager of the press department, Dan Prangsgaard, confirms that IT systems of several airlines are affected. Passengers there are also compelled to undergo a time-consuming manual check-in, even though operations are generally functioning satisfactorily.
The error in the IT systems is due to a failed update of the antivirus program CrowdStrike, impacting computers worldwide. Microsoft computers have been affected since Friday morning Danish time. Airlines such as SAS, Lufthansa, and Air France have also reported issues; SAS particularly mentioned difficulties with online flight ticket booking, according to the Norwegian news agency NTB.
The technical challenges have not only hit the aviation sector. In Denmark, the Capital Region Preparedness (Hovedstadens Beredskab) has had problems receiving automatic ABA alarms, which are usually sent to the alarm center in case of a fire. DSB (Danish State Railways) has also been affected, as both their website and app were temporarily down. However, by 11:30, DSB announced that their website was back up and running.
The Center for Cyber Security (CFCS) has declared on the social media platform X that they are aware of the issue, likely stemming from an error in an update of the security program Crowdstrike Falcon. CFCS is closely monitoring the situation.
