Dense Fog Triggers 148 Flight Cancellations at Delhi Airport

Severe weather caused major disruption at the Indira Gandhi International Airport (IGIA) in Delhi. Dense fog and extremely low visibility conditions crippled air traffic on Wednesday, December 31, 2025. At least 148 flights were cancelled. This included 78 arrivals and 70 departures. Additionally, over 150 flights faced significant delays. Two flights were also diverted from the national capital.

Operational Challenges and CAT III Protocols

Airport operator Delhi International Airport Ltd (DIAL) confirmed the widespread disruption. The airport handles about 1,300 flight movements daily. Operations were shifted to CAT III B protocols due to the poor visibility.

Category-III is an advanced navigation system. It allows aircraft to land in very foggy conditions. CAT-III B specifically permits landings with a Runway Visual Range (RVR) under 50 meters. Airlines must use CAT-III compliant aircraft. They must also roster pilots trained for these low-visibility operations.

DIAL issued a passenger advisory early in the morning. It warned travelers of potential delays and cancellations. Visibility was reported to be improving later in the day. However, some flight schedules remained affected.

Industry and Regulatory Response

Airlines quickly responded to the challenging conditions. Major carriers like IndiGo, Air India, and SpiceJet issued travel advisories. They urged passengers to check their flight status. Air India proactively cancelled some morning flights. It also activated its 'FogCare' initiative.

The Ministry of Civil Aviation (MoCA) and the Directorate General of Civil Aviation (DGCA) intervened. They instructed airlines to strictly follow passenger service norms. These rules cover timely information and assistance during delays. They also mandate rebooking or refunds for cancellations.

Aviation disruption in northern India is common during the winter fog season. The DGCA has a specific framework for these low-visibility procedures (LVP). Delhi is one of six Indian airports certified for CAT III operations. This preparedness is crucial for maintaining safety. It also helps minimize the economic impact on air travel. Stakeholders across the industry rely on clear, up-to-date information. This helps manage the flow of passengers and cargo effectively. For more commercial aviation news, visit flying.flights.

Key Details for Passengers

• Impact: 148 flights cancelled, over 150 flights delayed.
• Cause: Dense fog forced CAT III B operations.
• Airlines: IndiGo, Air India, and SpiceJet issued advisories.
• Regulatory Action: DGCA mandated strict adherence to passenger service norms.

This event highlights the operational risks of winter weather. It stresses the importance of advanced navigation systems. It also shows the need for robust passenger communication. The International Air Transport Association (IATA) stresses operational safety. This remains the top priority during low-visibility events.
