NEW DELHI: Flight operations across several parts of the country were severely affected after dense fog reduced visibility, leaving passengers stranded and distressed at multiple airports. The aviation regulator, the Directorate General of Civil Aviation (DGCA), has announced the period from December 10 to February 10, 2026, as the official fog window for this season. At Delhi airport, visibility dropped sharply to around 125 metres, significantly impacting flight movements.
Sharing a passenger advisory on X, the Delhi Airport said that “flight operations are currently being conducted under CAT III conditions due to dense fog, which may result in delays or cancellations.” The airport authority also advised travellers to stay updated by checking their flight status with the respective airlines. Several inbound flights to Delhi were diverted owing to poor visibility, air traffic congestion and cascading delays, further adding to passenger inconvenience.
Airlines also issued advisories, warning of possible cancellations and delays. IndiGo posted an update on X stating, “Dense fog in Jammu continues to affect visibility, impacting flights operating to and from Jammu. As conditions evolve, some services may experience delays, and a few may need to be cancelled depending on clearance and operational feasibility.”
SpiceJet issued its last update around midnight, informing passengers about disruptions in Kolkata. “Due to bad weather (poor visibility) in Kolkata (CCU), all departures/arrivals and their consequential flights may be affected. Passengers are requested to keep a check on their flight status,” the airline said in a statement. Air India also cautioned passengers that routes across North India, including its primary hub in Delhi, were likely to be impacted due to dense fog-induced low visibility. The airline warned that this could have a cascading effect on flight schedules across its domestic network. The Airports Authority of India (AAI) issued a broader warning, highlighting possible disruptions and sharing helpline numbers of airlines for passenger assistance.
