Earlier today the Delhi airport authorities issued a passenger advisory at 5:06 am on X, formerly Twitter, saying that low visibility procedures are in progress at the airport and that all flight operations were normal at the time.
This post was soon followed by a post by ANI which said that several flights had been delayed at the Delhi airport. A visual shared by the news agency showed the flight information screens showing delay for some flights. The video further showed a thick blanket of fog engulfing the tarmac and the airplanes.
