IndiGo, India's largest carrier, issued a travel advisory on Saturday alerting passengers to potential flight disruptions stemming from anticipated dense early-morning fog across Delhi and various regions of northern India on Sunday. The airline specified that reduced visibility during these crucial early hours could significantly impact flight operations, potentially leading to delays, diversions, or schedule changes. Safety remains the paramount concern for the carrier during these seasonal weather events.

The airline confirmed that its operations teams are actively monitoring weather conditions minute-by-minute to mitigate inconvenience. IndiGo advised all affected travelers to check the latest flight status before proceeding to the airport and provided options for rebooking or requesting refunds via its Plan B system for passengers whose flights are impacted.

This advisory follows significant disruptions already experienced at major hubs. On Saturday, Indira Gandhi International Airport (DEL) reported that 66 arrival and departure flights were canceled due to low visibility caused by dense fog. Delhi Airport confirmed that low-visibility procedures (LVP) were in effect but stated that all flight operations were functioning normally despite the conditions, advising passengers to contact their specific airlines for the most current updates. Furthermore, Srinagar Airport reported four flight cancellations, three of which were linked to adverse weather conditions in Delhi and Amritsar.
