Heavy fog enveloped the IGI airport this morning, disrupting the schedule of over a dozen flights.
About 13 domestic and international flights were delayed by upto two to three hours after fog descended on the airport on Christmas morning, an airport official said.
The fog started to descend on the airport in the wee hours forcing the airport authorities to implement Low Visibility Procedures (LVP).
The general visibility dropped to less than 50 metres while the runway visibility dropped to 100 metres on the main runway while it hovered between 500 to 125 metres on the new runway.
Some of the international flights arriving here early morning from Hong Kong, Zurich, Bangkok, Frankfurt and London were delayed by up to two to three hours.
Flights to Chandigarh, Amritsar, Goa, Patna, Kochi and other destinations were also delayed by up to two hours, causing inconvenience to the flyers, who had planned their Christmas holiday.
