Air and rail traffic was affected due to poor visibility and the Indira Gandhi International Airport (IGIA) in New Delhi had to activate low visibility procedures to ensure safe and staggered movement of incoming and outgoing flights.
At least 21 trains arriving or departing from New Delhi were running late, indicated reports.
Privately-run Vistara airliner informed its passengers about flight delays due to adverse weather conditions over Delhi.
Another private airline Indigo, also put out a similar message on social media, urging passengers to check on their flight's arrival and departure status.
Trains were also running late, the ANI news agency reported.
IGIA in Delhi is the busiest airport in the country and currently handles 1,324 flight movements on a daily basis. This figure is set to go beyond 1,500 flights per day, according to airport management sources.
Meanwhile, massive disruptions in road traffic movement, due to protests against a controversial citizenship law, have also been cited as responsible for delays in flight departures.
