Dense Fog Disrupts Delhi Airport Flights

Dense fog has severely disrupted flight operations at India — Indira Gandhi International Airport and other airports across Northern India since mid-December 2025. This has led to hundreds of flight cancellations and delays, impacting major airlines like IndiGo, India, and SpiceJet. Authorities such as the India — Airports Authority of India, India — Ministry of Education (India), and Malaysia — Malaysian Meteorological Department have issued advisories and implemented low-visibility procedures (CAT III) to manage the situation. The persistent fog, combined with poor air quality in India — Delhi, has caused significant inconvenience to passengers and financial losses for airlines, with IndiGo alone cancelling over 100 flights on multiple occasions. The India — Directorate General of Civil Aviation (India) has declared a 'fog window' from December 10 to February 10, highlighting the recurring nature of this winter challenge.
