Dense fog, smog and ‘poor’ air quality index (AQI) continued to plague the Delhi-NCR region, affecting flights at the Indira Gandhi International Airport (IGIA), where flight operations are being operated in CAT III conditions.
Airport authorities stated in a post on X that passengers may experience delays or disruptions.
“Flight operations continue to be in CAT III. Both arrivals and departures are taking place, though some flights may experience delays or disruptions. Passengers are requested to contact their respective airlines for the latest flight information,” DAA said.
CAT III is a category of Instrument Landing System (ILS) that offers lower minimums for visibility and decision height, even allowing for almost zero visibility landings in some cases. Advanced equipment and pilot training are required for CAT III approaches.
Similarly, major airliner IndiGo, said in a post on X that fog and low visibility over cities including Delhi, Amritsar, Bhopal, Chandigarh, Guwahati, Varanasi, Ranchi, and Hindon Airport may impact flight schedules.
“Low visibility and fog over Delhi, Amritsar, Bhopal, Chandigarh, Guwahati, #Varanasi, Ranchi and Hindon (Airport) may impact flight schedules. We are closely monitoring the weather and doing our best to get you where you need to be, safely and smoothly. We request that you stay updated on your flight status via our website or app. Please be assured that our teams are here to assist you at every step and provide full support. We look forward to clearer skies and a swift return to our regular schedule. Thank you for your patience and understanding,” IndiGo wrote on X.

The Central Pollution Control Board (CPCB) data put Delhi’s AQI at 288 on Tuesday, which comes in the ‘poor’ category.
Several hotspots recorded even higher pollution levels, with Anand Vihar at 343, RK Puram at 324, Jawaharlal Nehru Stadium at 313, Dwarka at 307, Ashok Vihar at 302 and ITO at 286. Some areas also reported relatively better ‘moderate’ air quality, with Bawana at 194 and IGI Airport at 185.
Subsequently, the sub-committee on the Graded Response Action Plan (GRAP) of the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) revoked Stage-III of GRAP on Friday evening, following a significant improvement in air quality due to favourable meteorological conditions.
The government has urged people to strictly adhere to the citizen charter under Stages II and I of the extant schedule of GRAP so that the AQI level does not slip further.
