• Airlines worldwide have complied with an EAD issued by EASA.
• Operators must replace or modify affected ELAC B L104 computers.
• Limited ferry flights are permitted to reposition aircraft for maintenance.
• Most aircraft can return to service quickly, while some may require more time and spares.

This development may indicate airlines' preparedness for addressing emerging technical issues. The swift compliance suggests that operators may be prioritizing operational resilience in the face of potential disruptions. However, the varying impact on different airlines may suggest that some carriers may face more significant challenges in the short term.
