An official statement from the entity warned of possible delays and the need for airlines to activate contingency plans.

The impact was noticeable in various terminals, with longer lines, slower processes, and passengers forced to adapt to new instructions.

Travelers can print boarding passes and baggage tags at self-service kiosks, but assisted check-in is limited.

Malaysia Airports Holdings Bhd urges passengers to check in online whenever possible and follow the instructions of staff in the terminals.

The failure was caused by a global problem in Microsoft systems, originating from a faulty antivirus update that caused widespread disruptions.

Airlines, airports, banks, hospitals, and media outlets in various countries reported disruptions as a result.

According to Microsoft, the cause has been identified and corrected, and the affected applications are gradually being restored.
