Low-visibility conditions continued to disrupt air travel across the Delhi-NCR on Wednesday (24 December), prompting an advisory from Indira Gandhi International Airport (IGIA) as fog, haze and hazardous air quality affected the national capital.
Airport authorities said low-visibility procedures remain in effect, and passengers are advised to check their flight status before heading to the airport, as there is a risk of delays and cancellations.
In its latest advisory, Delhi Airport confirmed that low-visibility procedures are currently operational at IGIA. These protocols are typically implemented during winter fog to ensure safe aircraft movements, but often result in slower take-offs, landing delays and disrupted schedules.
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.
Further worsening the situation, Delhi’s air quality remains poor. The Air Quality Index (AQI) stood at 325 on Wednesday, placing it in the hazardous category. The dominant pollutants were PM2.5 and 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 the AQI crosses 100, sensitive groups, including children, the elderly and those with respiratory conditions, should limit their outdoor exposure. When air quality is ‘poor’ or worse, residents are advised to reduce outdoor activity and wear masks when stepping outside.
