Air India Express has faced widespread disruptions with over 90 flights canceled due to an unexpected sick call from 300 senior cabin crew members. The cancellations stem from grievances over revised job conditions and alleged unfair treatment post-merger with Tata Group, including claims of demotions, changes to compensation, and suppression of dissent. Air India Express has confirmed the cancellations and is working to resolve the situation, offering refunds or rescheduling options to affected passengers. The incident highlights the challenges faced by airlines during mergers, as cabin crew express dissatisfaction with perceived unfair employment practices. This disruption follows similar issues at Vistara, another Tata Group airline, where pilots have raised concerns over roster management and salary changes.
