The Ministry of Civil Aviation ordered IndiGo, India's largest airline with over 60% domestic market share, to cut its services by 10% after it cancelled nearly 4,500 flights in early December 2025. The crisis began on December 2 when IndiGo failed to adjust to new DGCA flight crew time limitations.

IndiGo vacated 717 flight slots from its domestic winter schedule. DGCA imposed a penalty of ₹22.20 crore on the airline, gave a temporary exemption from new rules till February 2026, placed caps on airfares, and ordered completion of all pending refunds. The disruption affected hundreds of thousands of passengers nationwide.
