December 8, 2025, marked a turning point in the IndiGo flight disruption crisis as cancellations began to taper off following the DGCA's emergency exemption granted on December 5, 2025. The crisis, which began on December 2, had led to nearly 4,500 flight cancellations over ten days, with the worst day — December 5 — seeing approximately 1,600 cancellations. IndiGo, which holds over 60% of India's domestic aviation market share, had failed to adequately plan for the second phase of new Flight Duty Time Limitation (FDTL) rules, which came into force on November 1, 2025. These rules increased mandatory weekly rest for pilots from 36 to 48 hours and restricted night landings to just two per week per pilot — dramatically increasing crew requirements. On December 5, the DGCA granted IndiGo a temporary exemption until February 10, 2026, modifying the definition of 'night' from midnight–6 AM to midnight–5 AM, allowing up to six night landings per week, and withdrawing the clause barring substitution of weekly rest with leave. By December 8, operations were stabilising, though stranded passengers continued to seek refunds and compensation. The crisis exposed systemic weaknesses in Indian aviation — inadequate crew planning by airlines, the tension between safety regulations and operational demands, and the need for stronger DGCA oversight and penalty mechanisms. The Ministry of Civil Aviation announced an inquiry into IndiGo's scheduling failures.
IndiGo Flight Disruption Eases on December 8; DGCA FDTL Exemption Takes Effect as Cancellations Taper from Peak of 1,600

Mains angle
Q: What systemic weaknesses in Indian civil aviation did the IndiGo December 2025 crisis expose?
Answer (50 words):
IndiGo's 60% domestic market share amplified disruption as nearly 4,500 flights were cancelled in ten days. New FDTL rules increasing pilot weekly rest from 36 to 48 hours strained crew scheduling amid rapid fleet expansion without proportional recruitment. DGCA granted temporary exemptions until February 2026 while the Ministry announced an inquiry.

Frequently asked questions
What are Flight Duty Time Limitations (FDTL) rules and why did DGCA revise them in November 2025?
FDTL rules regulate the maximum hours a pilot can fly and the minimum rest they must receive to prevent fatigue-related accidents. DGCA revised the rules effective November 1, 2025 to strengthen safety standards — increasing mandatory weekly rest from 36 to 48 hours and imposing stricter limits on night landings (defined as landings between 00:00 and 05:00 hours).
What was the scale of the IndiGo flight disruption crisis in December 2025 and what triggered it?
The crisis began December 2, 2025 and caused approximately 4,500 cancellations over ten days. The worst single day was December 5 with around 1,600 cancellations. The trigger was IndiGo's failure to plan adequately for the second phase of new FDTL rules, leaving insufficient crew availability to operate its full schedule of approximately 2,200–2,300 daily flights.
What emergency exemption did DGCA grant to IndiGo on December 5, 2025 and why was it controversial?
DGCA granted IndiGo a temporary exemption modifying the definition of 'night' (adjusting the restricted window) and permitting up to six night landings per week instead of the previous limit. This was controversial because pilot unions argued it undermined the safety objectives that the new FDTL rules were designed to achieve, effectively suspending protections under public pressure rather than addressing root scheduling failures.
What does the IndiGo crisis reveal about the relationship between airline deregulation and aviation safety in India?
The crisis revealed a structural tension: rapid market deregulation allowed IndiGo to capture 60%+ market share and grow its fleet aggressively, but crew training and rostering systems did not scale proportionally. It demonstrated that aviation safety regulation (FDTL) must be backed by proactive compliance monitoring — and that when a single airline dominates 60% of a market, its operational failure has systemic consequences for millions of passengers.
What regulatory action did the Ministry of Civil Aviation announce following the IndiGo FDTL crisis?
The Ministry of Civil Aviation announced an inquiry into IndiGo's scheduling failures, examining whether the airline had violated the new FDTL rules and failed to maintain adequate crew buffers. DGCA also ordered IndiGo to reduce its winter flight schedule — first by 5% (approximately 110–115 daily flights), later doubled to 10% — as a corrective measure.
