Domestic carrier IndiGo cancelled 67 flights on Thursday across several airports as widespread fog and poor visibility disrupted operations nationwide. According to the airline’s website, only four flights were grounded due to operational reasons while the remaining cancellations were triggered by forecasted bad weather at airports such as Agartala, Chandigarh, Dehradun, Varanasi and Bengaluru. The disruptions come during the DGCA’s officially declared fog window that runs from December 10 to February 10.
