Airlines such as Air India, SpiceJet, and IndiGo have attributed potential flight delays to heavy fog and poor visibility affecting Delhi and several regions across northern India. As thick fog blanketed the national capital and surrounding areas, these carriers issued travel advisories on Friday, cautioning passengers about possible disruptions to flight operations. Delhi Airport also released an alert, urging travelers to verify their flight status before arriving at the airport.
Air India stated on Thursday that weather forecasts predicting dense fog over Delhi and parts of northern and eastern India on Friday could impact flight schedules. The airline added that such conditions might lead to knock-on effects throughout its network. In a post shared on X, Air India said it had already implemented precautionary steps to reduce inconvenience for passengers.
The airline assured travelers that ground staff would provide support and arrange alternatives in case of unforeseen delays or cancellations. Under a special initiative, passengers booked on flights likely to be affected will receive advance notifications. They will be allowed to reschedule their journey without additional charges or opt for a full ticket refund.
Passengers were advised by all airlines to check the latest flight updates before heading to the airport.
IndiGo also issued a similar advisory early Friday, citing widespread morning fog across northern India. The airline warned that early-morning departures might face delays or changes in timing. IndiGo said it is closely tracking weather developments and working with air traffic control to limit passenger inconvenience.
SpiceJet, meanwhile, shared a weather update on X, noting that low visibility in Delhi could impact both departures and arrivals, along with connecting flights.
Delhi Airport confirmed that CAT III operations had been activated due to dense fog, which has led to delays and operational challenges. CAT III systems enable aircraft to land safely even in extremely low-visibility conditions. The airport added that its ground teams are coordinating with all stakeholders to assist passengers.
Earlier on Thursday, visibility in Delhi-NCR dropped sharply, with the India Meteorological Department (IMD) reporting levels as low as 100 metres around 6:00 am. According to officials, at least 27 flights were cancelled, while around 500 others experienced delays.
