New Delhi:The thick blanket of fog resulting in poor visibility in the winter-battered north India has affected the operation of over 500 flights, an official from the Delhi airport said on Monday.
"Over 500 flights have been delayed, 21 diverted, and five flights have been cancelled due to dense fog at Delhi Airport," the official said.
Private airlines IndiGo and Vistara on Monday issued a travel advisory for their passengers saying flights to and from the national capital have been impacted due to bad weather and poor visibility.
Dense fog and eventual poor visibility have caused flight delays and cancellations across north India in the past few days.
Dense fog and bone-chilling cold continued unabated in several parts of north India, affecting normal life.
Delhi's IGI airport authorities had earlier warned that flight departures may be impacted if visibility droppped below 125 metres.
