India's Directorate General of Civil Aviation (DGCA) ordered IndiGo, the country's largest airline with over 60% market share, to reduce its flight schedule by 5% following a severe scheduling crisis in December 2025 that resulted in thousands of flight cancellations and left lakhs of passengers stranded or severely delayed. The crisis was triggered by a combination of pilot shortages, aircraft maintenance issues, and overambitious scheduling that outpaced IndiGo's operational capacity. DGCA's intervention came after sustained passenger complaints and media reports of chaos at major airports including Delhi, Mumbai, and Bengaluru. The regulator's order was subsequently enhanced to a 10% reduction by the Ministry of Civil Aviation as IndiGo's operational situation did not stabilise. The crisis exposed systemic issues in India's fast-growing civil aviation sector — including inadequate pilot training pipelines, lack of redundancy in crew scheduling, and the risks of rapid fleet expansion without commensurate infrastructure. DGCA later levied a penalty of ₹22.20 crore on IndiGo for the disruptions, requiring sweeping operational reforms. The episode reignited debates about consumer protection in aviation, DGCA's enforcement capacity, and the adequacy of existing regulations requiring airlines to compensate passengers for cancellations. India's aviation sector, which handled 152 million domestic passengers in 2024-25, is among the world's fastest-growing markets and requires strengthened regulatory oversight to match its scale.
