India's civil aviation regulator DGCA escalated its action against IndiGo on December 5, 2025, doubling the mandated flight schedule reduction from 5% to 10% (approximately 220-230 daily flights) after IndiGo reported 951 flight cancellations in November 2025 alone — its worst monthly figure. The escalation came as IndiGo continued struggling with compliance of new Flight Crew Time Limitation (FCTL) regulations issued by DGCA in line with ICAO safety standards. Since December 2, the crisis had caused approximately 4,500 cancellations in ten days, stranding thousands of passengers. The episode highlighted systemic issues: rapid fleet expansion without proportional crew recruitment and training, inadequate rostering software, and failure to build buffer in crew scheduling. IndiGo holds 60%+ of India's domestic aviation market (approximately 2,200 daily flights), meaning its disruptions have disproportionate consumer impact. The crisis reignited debate around Air Passenger Rights legislation in India — unlike the EU's EC 261/2004, India lacks automatic, legally-mandated compensation for airline-caused cancellations.
