Dense smog in New Delhi causes major flight disruptions

Heavy smog caused by severe air pollution over New Delhi, India, has delayed more than 250 flights.

Poor visibility has led to the cancellation of 22 flights, CaliberAz reports via Hindustan TImes.

The city’s latest air quality index stands at 358, indicating hazardous pollution levels.

Temporary measures came into effect on December 18, to combat the crisis, including a shift to hybrid work for office employees and restrictions on certain vehicles entering the city.

Delhi’s authorities have activated the highest emergency level of their winter pollution response plan (Graded Response Action Plan) after the AQI consistently rose into the severe category, prompting vehicle bans, construction suspension and work‑from‑home directives to try to curb emissions. 

Persistent dense smog combined with winter weather conditions has sharply reduced visibility across the capital, as the AQI in many areas remains very poor to severe, aggravating health risks and daily life disruptions. 

Airlines and airport authorities have issued travel advisories due to visibility dropping as low as roughly 100 metres in some places, contributing to delays and cancellations at Indira Gandhi International Airport. 

Environmental data firms report that Delhi repeatedly ranks among the most polluted major cities globally during winter months, with AQI occasionally reaching hazardous levels, reflecting long‑standing air quality challenges that affect residents and transport alike.
