Understanding IndiGo's Current Operational Crisis
The December 2025 Disruptions Timeline
The new cancellations represent a continuation of IndiGo's severe operational challenges that began earlier in December 2025. The airline faced a compounding crisis when it canceled nearly 4,500 flights between December 1-9, creating what regulators and industry observers have called the most significant aviation disruption in India's recent history.[1]
Crisis Timeline:
· December 2-5: Peak disruption period with over 1,600 flights canceled on December 5 alone
· December 5: IndiGo initiated a "network reboot" strategy, temporarily canceling significant flights to decongest airports
· December 6-8: Operations began gradually normalizing, though disruptions continued
· December 9: DGCA ordered a 10% reduction in IndiGo's flight schedule
· December 10-25: Winter fog season begins, bringing additional operational challenges
· December 26 onwards: Continued cancellations (67 flights canceled on Thursday)
The scale of these disruptions has impacted every major airport in India, with the crisis occurring during India's peak wedding season, compounding passenger inconvenience and economic impact.[1]
Current Operational Capacity Restrictions
Flight Schedule Reductions:[1][2]
· Original Winter Allocation: 2,144 daily domestic flights
· Current Reduced Capacity: 1,930 daily domestic flights (10% reduction mandated by government)
· Grounding Impact: Effectively removing 214 flights from daily operations
This capacity restriction represents a significant reduction for India's largest airline, which operates over 60% of India's domestic market share. The reduction directly impacts passengers and may provide competitive advantages to other carriers like Air India, SpiceJet, and Vistara.

Root Causes: From Pilot Rest Rules to Weather Challenges
The Pilot Duty Time Limitation (FDTL) Rules Crisis
The initial crisis in early December stemmed from IndiGo's failure to implement new Flight Duty Time Limitation (FDTL) Phase II rules that took effect on November 1, 2025.[3][4]
The New Pilot Rest Regulations:[4][5]
The DGCA implemented stricter pilot fatigue management rules designed to protect both pilot safety and passenger security:
· Weekly Rest Increase: Extended from 36 hours to 48 hours (12-hour increase)
· Continuous Rest Requirement: Minimum 48 hours of continuous rest including two local nights
· Maximum Weekly Hours: No more than 168 hours between weekly rest periods
· Leave Calculation: Personal leave must be additional to (not counted as part of) required rest periods
· Night Flying Restrictions: Maximum 8-hour flight time and 10-hour flight duty for night operations
· Night Landing Limits: Reduced from 6 landings to 2 landings per night
IndiGo's Implementation Failure:
Despite advance notice and DGCA guidance to undertake "comprehensive manpower planning, roster restructuring, and implementation preparedness," IndiGo failed to adequately prepare crew schedules, leading to massive pilot unavailability.[6]
· Poor planning and insufficient staff for schedule changes
· Crew rostering system failures that didn't account for new rest requirements
· Inadequate pilot hiring or contract crew arrangements
· Underestimation of impact on crew availability
· Operational readiness deficiencies identified by regulators
Compounding Factors Beyond Pilot Rules
IndiGo itself identified multiple factors contributing to the crisis:[3]
1. Schedule Changes Linked to Winter Season: Adjusting flight networks for seasonal demand
2. Minor Technical Glitches: Aircraft maintenance and technical issues
3. Adverse Weather Conditions: Including fog, which becomes severe during winter
4. Increased System Congestion: Reduced capacity at major airports during peak periods
The "Unfortunate Confluence": IndiGo acknowledged in its official response to DGCA that a "compounding effect of multiple factors" and an "unfortunate and unforeseeable confluence" of circumstances created a perfect storm of operational challenges.[3]
Winter Fog Season: Navigating CAT-IIIB Technology Requirements
Winter Fog Season Framework (December 10 - February 10)
The DGCA has officially declared a winter fog season from December 10, 2025 to February 10, 2026, during which special operational procedures and equipment requirements apply to all airlines.[7][8][2]
Dense Fog Impact on Flight Operations:[8][7]
Dense fog in northern India, particularly around Delhi, creates a cascading effect on flight schedules across the entire network:
· Visibility Reduction: Fog reduces visibility to 50 meters or less at affected airports
· Capacity Degradation: Flight handling time increases from 1 minute per flight to 3+ minutes per flight
· Zero-Visibility Shutdowns: When visibility drops below CAT III requirements (below 75 meters), even equipped airports must halt operations
· Runway Limitations: Aircraft can land but cannot taxi on runways in sub-zero visibility conditions
· Alternate Diversions: Flights must be diverted to alternate airports when primary airports become unusable
CAT-IIIB Technology: Understanding Low Visibility Operations
What is CAT-IIIB?
CAT-IIIB (Category IIIB) refers to low-visibility landing operations using specialized Instrument Landing Systems (ILS). The requirement represents one of the highest levels of precision aviation technology:[7]
CAT-IIIB Specifications:
· Visibility Requirement: Can operate at visibility as low as 50 meters (compared to 200+ meters for standard operations)
· Technological Component: Specialized Instrument Landing System (ILS) that provides precise guidance during landing
· Pilot Certification: Requires specially trained pilots with specific flight hour minimums:
o Captain: Minimum 500 hours of flying experience
o First Officer: Minimum 300 hours of flying experience
· Aircraft Equipment: Aircraft must be equipped with CAT-IIIB-certified avionics and landing systems
· Ground Infrastructure: Airports must have ILS systems installed and maintained to CAT-IIIB standards
Current Infrastructure Limitations in India:[8][7]
Despite having modern aircraft, India's airport infrastructure lags behind:
· Only 6 Airports with Full CAT-IIIB: Delhi, Lucknow, Jaipur, Amritsar, Bengaluru, and Kolkata
· About 40 Airports Affected by Fog: Primarily in northern and northeastern regions
· Infrastructure Gap: Majority of aircraft are CAT-IIIB equipped, but airport systems need upgrading to facilitate operations
The Practical Limitation:[7]
Even CAT-IIIB-equipped airports face operational challenges during extreme fog:
· Zero-visibility scenarios (below 75 meters for landing, 125 meters for takeoff) require complete operational shutdown
· When visibility drops below these thresholds, airports cannot operate regardless of equipment capabilities
· During severe fog, Delhi's four runways experience severe capacity constraints, creating network-wide pile-ups

Affected Airports and Impact Zones
Airports Directly Affected by December 26 Cancellations:[2]
· Agartala (Northeast): Limited CAT-IIIB infrastructure
· Chandigarh (North): Vulnerable to winter fog patterns
· Dehradun (North): High altitude, prone to fog and weather disruptions
· Varanasi (Central): Regional hub affected by network congestion
· Bengaluru (South): Major hub with weather-related disruptions
Alternate Diversion Airports:
When primary airports are affected by dense fog, flights are diverted to:
· Jaipur
· Ahmedabad
· Lucknow
· Nagpur
· Bhopal
· Indore
These diversions create additional operational complexity, increased ground handling costs, and passenger inconvenience.
