Air India, IndiGo warn of impact on flight schedules amid IMD's dense fog forecast in Delhi, North India on 31 December
Air India and IndiGo have issued advisories warning of potential flight delays at Delhi's Indira Gandhi International Airport due to the prevailing fog in the area.
Dense fog is expected to continue blanketing Delhi on Wednesday, 31 December, which is New Year’s Eve, leading to reduced visibility. In view of the conditions, several airlines have issued advisories urging passengers to check their flight status before heading to the airport.
IndiGo, India’s largest and most dominant airline, in a post on X wrote: "Dense fog across the northern belt continues to persist, causing reduced visibility and ongoing disruptions to flight schedules.
