The Directorate General of Civil Aviation (DGCA) on December 9, 2025, directed IndiGo, India's largest airline with over 60% domestic market share, to reduce its flight operations by 5% across sectors. The order came after IndiGo's failure to operate its winter schedule efficiently, caused by inability to adjust to new flight crew time limitations mandated by DGCA.

The crisis, which started on December 2, led to nearly 4,500 flight cancellations over ten days. The Ministry of Civil Aviation later doubled the curtailment to 10% due to IndiGo's continued inability to restore normal operations. IndiGo had cancelled 951 flights in November alone. The airline was asked to submit a revised schedule by 5 PM on December 10.
