New Delhi: Flight operations at Indira Gandhi International Airport and several other airports in north India were disrupted on Monday as dense fog sharply reduced visibility, leading to widespread delays and cancellations. Airport authorities said at least 40 flights were cancelled, while a few others were diverted due to adverse weather conditions.
The Airports Authority of India (AAI) issued an advisory urging passengers to confirm the status of their flights with airlines before travelling to the airport, warning that poor visibility could result in prolonged waiting times. Officials said air traffic control teams were working in close coordination with airlines and ground staff to manage operations safely and minimise inconvenience to travellers.

Airlines also issued advisories warning of possible disruptions. IndiGo, the country’s largest carrier, said low visibility caused by fog over Delhi was impacting flight schedules and that teams were closely monitoring weather conditions. The airline cautioned that some flights could be cancelled in the interest of safety and advised travellers to check flight status updates before leaving for the airport.
Air India also alerted passengers about operational challenges caused by dense fog in the capital and parts of northern India. The national carrier urged travellers to stay informed by checking flight details on its official website before commencing their journey.
The Ministry of Civil Aviation also appealed to passengers to remain alert and plan accordingly, advising them to allow additional time for travel. In a public message, the ministry said dense fog conditions were affecting visibility at Delhi and other northern airports, and stressed that safety considerations remained the top priority during flight operations.
Authorities said flight movements would continue to depend on weather conditions, and further disruptions could not be ruled out if visibility levels failed to improve. Passengers have been advised to regularly check official airport platforms and airline updates for the latest information.
