The advisory came as a thick layer of fog covered parts of Delhi early in the morning, significantly reducing visibility across the city.

In addition to Republic Day-related disruptions, Air India issued another advisory earlier in the day warning of potential delays due to dense fog and airport congestion.

Air India began flying its long-anticipated route between Newark Liberty International Airport (EWR) and Indira Gandhi International Airport (DEL) in Delhi. The direct flight is aboard a state-of-the-art Airbus A350-900 and follows the recent introduction of a similar route from New York’s John F.

Delhi airport advised passengers to stay updated on schedules by coordinating with airlines to avoid disruptions. The IMD said cloudy skies are expected throughout the day, with light rain or drizzle likely in some areas.

NCR, including Ghaziabad and Noida, had close to zero or complete zero visibility amid the dense fog on Wednesday.
