Dense fog continued to blanket the national capital on Tuesday, triggering widespread flight disruptions at Indira Gandhi International (IGI) Airport.

As of around 9.30 am, at least 118 flights were cancelled at Delhi airport, while over 200 flights were delayed and another 118 were diverted, officials said.

AAI Issues Advisory

According to the India Meteorological Department (IMD), visibility at IGI Airport dropped to 350 metres at 9.30 am, indicating dense fog conditions. The adverse weather also affected train services, further compounding travel disruptions across the national capital.

In response, the Airports Authority of India (AAI) issued an advisory cautioning passengers about possible delays at select airports in northern India due to reduced visibility. In a post on X, the AAI urged travellers to stay in contact with their respective airlines for the latest updates and to allow additional time for airport formalities. The authority also said assistance teams had been deployed at affected airports to support stranded passengers.

IndiGo, in a travel advisory issued late Monday night, warned that early-morning fog could sharply reduce visibility at airports including Delhi, Amritsar, Chandigarh, Jammu, Kolkata, Ranchi, Guwahati and Hindon, potentially impacting flight operations.

Fog-related disruptions were also reported on Monday, when 128 flights were cancelled at Delhi airport and more than 200 were delayed before noon. Airlines have advised passengers to closely monitor flight status as foggy conditions are expected to persist.
