Bad Weather Hits IndiGo: 67 Flights Cancelled Across India

On Thursday, IndiGo cancelled 67 flights from several Indian airports as forecasted bad weather disrupted operations. Only four of the cancellations were due to operational reasons, while the remaining 63 flights were grounded due to adverse weather conditions affecting airports including Agartala, Chandigarh, Dehradun, Varanasi and Bengaluru, among others.

The disruptions come as India’s civil aviation regulator, the Directorate General of Civil Aviation (DGCA), has officially declared the period between December 10 and February 10 as the winter “fog window”, a stretch when low visibility and fog routinely challenge flight schedules. Under DGCA’s CAT-IIIB fog operation norms, airlines are required to roster pilots trained for low-visibility approaches and deploy aircraft equipped with Category-III landing systems capable of operating in dense fog, DGCA sources said.

According to experts, Category-III technology allows aircraft to land when runway visual range (RVR) conditions fall significantly, with CAT-III-A enabling landings with RVR as low as 200 metres, and CAT-III-B permitting operations below 50 metres.

IndiGo’s schedule continues to be monitored by the DGCA following mass cancellations earlier this month, including a single day of roughly 1,600 flight cancellations tied to new pilot rest norms, which led the government to trim its winter flying programme. Under the revised directive, the airline’s domestic daily flight limit was reduced from about 2,144 to 1,930 services, DGCA officials said.
