New Delhi: At least 200 flights were affected because of dense fog in the national capital on Saturday which led to chaos at Delhi’s Indira Gandhi International Airport (IGIA).

Passengers who were stuck at the airport for nearly nine hours complained of not being informed about the resuming of services. The Central Industrial Security Force (CISF) personnel also said that due to the flight cancellations and delays the airport looked like a “bus adda”.

“There are days when at least five to six flights are delayed, and we face a lot of problems while managing the passengers,” said the official.

“However, on Friday, it became very difficult to manage the passengers as many flights got diverted or delayed, and that resulted into a very crowded airport terminal,” added the official

The airport operator, Delhi International Airport Limited spokesperson, said, “Dense fog on Friday led to low visibility around the airport terminals, and because of that CAT III B has been activated since 5 am. Though departures took place till 5.30 am and the arrivals till 6 am, flight operations were affected.”

Flight operations were hit between 5.30 AM and 1 PM yesterday.”Around 97 per cent of these 450 flights were either departing or arriving beyond their scheduled time due to dense fog that remained till around 10.20am. Rest were either diverted or cancelled,” the official said.

Departures were largely put on hold between 5.30 AM and 10.20 AM. Arrivals were happening only intermittently between 6 AM and 7.20 AM, another official said.

The India Meteorological Department has said that dense fog is very likely over Delhi, Punjab, Haryana and Chandigarh in the morning. “Cold wave conditions at a few places very likely over Punjab and at isolated pockets over Haryana, Chandigarh and Delhi, West Uttar Pradesh, East Madhya Pradesh and interior Odisha,” the weather office said.
