KUALA LUMPUR: AirAsia's core reservation and check-in system have been affected by a global information technology (IT) issue, the low-cost carrier said in a social media posting.

"You may experience slower check-ins and longer queues and we are doing our best to address this situation. We appreciate your patience and understanding during this time," it said on the X platform.

Its statement issued at 4.52 pm comes following global news reports over Microsoft's cloud services outage affecting airlines worldwide.

Meanwhile, Malaysia Airports Holdings Bhd (MAHB), posting on X, also said its network of airports in Malaysia remains unaffected by the global Microsoft outage.

"However, some of our airline partners are experiencing disruptions due to this issue," it said.

MAHB earlier said its services were not affected by the global IT outage which has resulted in major travel disruptions in Europe, the United States as well as Australian airports.

AirAsia then had said that while the airline was experiencing an in-house system outage, there were no flight cancellations.

Similarly, it is understood that Malaysia Airlines is not affected.

While there seems to be no cancellations as of now, flights to destinations that have been affected by the global outage could affect Malaysia Airlines' flight.

However, Firefly's booking and online check-in systems are impacted by this issue.

In Singapore, the check-in process for some airlines at Changi Airport is being managed manually, as the global IT system outage is affecting many organisations, including those in the republic.

The Federal Aviation Administration has grounded flights from several major the United States carriers including Delta, United and American Airlines. All of Spain's airports are similarly affected, and Berlin Airport has also suspended flights due to outages.

There have been news reports coming from all over the globe pertaining to travel disruptions.

The reports cited issues linked to global cybersecurity firm Crowdstrike.

CrowdStrike Holdings Inc is an American cybersecurity technology company based in Austin, Texas. It provides penetration workload and endpoint security, threat intelligence and cyberattack services.

According to news reports, there could be a programming mistake which has the capability to bring down the entire computer, and that if someone makes the wrong type of mistake, it can bring the whole system down.
