India’s winter fog has once again thrown air travel into disarray, with dense visibility conditions forcing IndiGo to cancel and delay multiple flights across major airports. As thick fog blankets large parts of north and central India, airline operations remain under sustained pressure, affecting key domestic routes and disrupting travel plans during the peak winter season.

According to airline updates, IndiGo cancelled several flights on Friday morning, citing widespread fog and poor visibility at multiple airports. Unlike isolated disruptions, the current wave of cancellations reflects a prolonged weather challenge, with repeated route suspensions and knock-on delays across the network.

Which airports have been affected?

Bad weather conditions have significantly impacted operations at Varanasi’s Lal Bahadur Shastri International Airport and Chandigarh International Airport, two hubs particularly vulnerable to winter fog. IndiGo confirmed multiple cancellations scheduled for December 26, as forecasted low visibility continues to affect early-morning and late-night departures.

Flights impacted due to poor weather conditions include:

6E 714 | Bengaluru–Varanasi

6E 6044 | Varanasi–Chennai

6E 499 | Varanasi–Bengaluru

6E 401 | Chennai–Varanasi

At Chandigarh Airport, several services were also called off due to forecasted bad weather:

6E 146 | Chandigarh–Lucknow

6E 5261 | Chandigarh–Mumbai

6E 867 | Chandigarh–Hyderabad

6E 242 | Pune–Chandigarh

6E 627 | Chandigarh–Kolkata

These cancellations add to a growing list of disrupted routes connecting cities such as Varanasi, Bengaluru, Chennai, Mumbai, Hyderabad and Kolkata—underscoring how fog-related issues are affecting both business and leisure travellers.

Fog window officially in effect

India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), has already declared December 10, 2025, to February 10, 2026, as the official fog window for the winter schedule. During this period, airports across northern India routinely face reduced visibility, especially during early morning hours.

Civil Aviation Minister Rammohan Naidu recently reviewed winter preparedness with key stakeholders, including the DGCA, Airports Authority of India (AAI), airport operators, airlines and CISF. Despite precautionary measures such as low-visibility procedures and enhanced coordination, persistent fog continues to challenge flight operations.

Earlier this month, IndiGo had cancelled hundreds of flights nationwide, triggering widespread passenger inconvenience and highlighting the scale of disruption winter weather can cause to India’s aviation system.

Impact on passengers and travel planning

The ongoing India flight cancellations have affected a broad spectrum of travellers—from daily commuters and holidaymakers to international passengers transiting through major hubs. Data from recent disruptions shows:

• Repeated cancellations on the same routes over consecutive days.
• Impact across both domestic and international services.
• Delays affecting early-morning, late-night and peak-hour flights.

For passengers, this trend underlines the importance of closely tracking airline advisories, checking real-time flight status and allowing buffer time when planning journeys. Travellers flying through fog-prone airports are also advised to remain flexible with itineraries and stay alert for last-minute schedule changes.

As winter fog continues to tighten its grip, airlines and airports remain on high alert. With the fog window extending well into February, disruptions are expected to persist, making advance planning and constant updates essential for anyone flying over the coming weeks.
