Dense fog hits operations at Delhi airport; 128 flights cancelled, 8 diverted

Later around 1.15 pm, DIAL said: “Flight operations at Delhi Airport are running smoothly as runway visibility has improved. However, some flight departures or arrivals for certain destinations may be impacted.”

At airports certified for Category-III conditions, aircraft equipped with special landing systems and trained crews can operate even in very low visibility. However, it limits the number of flights that can operate during severe fog.

The Ministry of Civil Aviation had also issued an advisory in the morning, stating that flight operations at select airports in northern India could be affected by fog, leading to possible delays.

Airlines also issued advisories warning of possible disruptions.

In a post on X, IndiGo advised passengers to check flight status before leaving for the airport and to allow extra time for travel, as fog could also affect road traffic.

“Fog continues to persist across Delhi and several airports in northern India. Visibility remains reduced and, as a result, flight movements are presently slower than normal, with some delays being experienced. We will continue to manage operations under the prevailing conditions, sequencing departures and arrivals to maintain orderly operations,” the airline said.

Over the past few weeks, low visibility on several days led to flight delays, diversions, and cancellations, particularly in the early morning.
