Low visibility conditions continued to disrupt air travel across Delhi-NCR on Wednesday (24 December), prompting an advisory from the Indira Gandhi International Airport (IGIA) as fog, haze and hazardous air quality affected the national capital.
Airport authorities said low visibility procedures remain in force, while passengers have been advised to check flight status before heading to the airport amid the risk of delays and cancellations.
The situation follows significant disruption a day earlier, when at least 10 flights were cancelled and more than 270 were delayed on Tuesday due to dense fog and reduced visibility.
“Visibility at the airport is improving; however, flight departures for certain destinations may experience delay,” Delhi airport operator DIAL said in a post on X.
Adding to the disruption, Delhi’s Air Quality Index (AQI) stood at 325 on Wednesday, placing it in the hazardous category. The dominant pollutant was PM2.5, followed by PM10.
According to pollution data, PM10 levels were recorded at 253.67 and PM2.5 at 357.08, with nitrogen dioxide (NO2) at 67.24, sulphur dioxide (SO2) at 19.62, ozone (O3) at 15.1 and carbon monoxide (CO) at 65.16.
Health experts advise that when AQI crosses 100, sensitive groups such as children, the elderly and those with respiratory conditions should limit outdoor exposure. When air quality is “poor” or worse, residents are advised to reduce outdoor activity and wear masks when stepping outside.
