Delhi’s aviation sector faces significant operational challenges as the season’s first dense winter fog spell sweeps across Northern India on Monday, December 15, 2025. Major airlines including IndiGo, Air India, and SpiceJet have issued formal warnings to passengers regarding potential flight delays at Indira Gandhi International Airport due to severely reduced visibility conditions.
The fog outbreak is not limited to Delhi’s airport. Northern India’s broader aviation infrastructure is experiencing widespread impact from dense fog, with multiple airports across the region reporting substantially diminished visibility levels. According to reports from the Aviation Ministry, the deteriorating weather conditions are severely hampering flight operations across the region, affecting scheduled departures and arrivals.
The visibility reduction, characteristic of Northern India’s winter season, creates operational constraints for pilots and ground crews. Airlines are implementing standard fog-related protocols to ensure passenger safety, though these measures inevitably result in flight scheduling adjustments. Passengers are advised to check with their respective airlines for real-time updates on their flight status and to plan their airport visits accordingly, allowing extra time for potential delays.
