Dense fog has grounded hundreds of flights at major northern Indian airports, stranding thousands of passengers on the first day of the year. Visibility plummeted to near zero in several cities, forcing airlines to cancel or delay services indefinitely. Winter travelers, including large numbers of international tourists, now face cascading itinerary changes across the region.
Indira Gandhi International Airport in Delhi recorded the worst disruptions. More than 400 flights suffered delays, with over 100 cancellations affecting both domestic and international routes. Runway operations slowed dramatically as visibility dropped below 50 meters during peak morning hours.
Carriers including IndiGo, Air India, and SpiceJet issued the majority of cancellations. International flights from Europe, the Middle East, and Southeast Asia experienced the longest delays. Several inbound aircraft diverted to alternate airports in Ahmedabad, Mumbai, and Jaipur.
Similar conditions impacted secondary hubs in Lucknow, Chandigarh, Amritsar, Patna, and Varanasi. Regional airports reported cancellation rates exceeding 60 percent on short-haul routes. Low-cost carriers operating dense northern networks adjusted schedules throughout the day.
The India Meteorological Department confirmed radiation fog formation due to calm winds and high moisture retention. Dense fog alerts cover Punjab, Haryana, Delhi, Uttar Pradesh, and parts of Rajasthan and Bihar. Forecasts predict persistence of conditions for at least five more days.
Airport authorities activated Category III-B instrument landing systems at Delhi’s newest runway to maintain limited arrivals. Fog dispersal measures, including runway heating trials, remain under evaluation for future seasons. Passenger facilitation counters distributed meals and refreshments to stranded travelers.
International tourists transiting through Delhi en route to Agra, Jaipur, and Varanasi faced the greatest inconvenience. Golden Triangle circuits typically see peak winter bookings from European and North American markets. Ground handlers reported widespread hotel rebookings and tour rescheduling requests.
Railway services registered sharp demand surges on parallel routes. Additional special trains deployed between Delhi, Agra, and Amritsar to accommodate diverted passengers. Vande Bharat Express services operated at near-full occupancy on affected corridors.
Highway authorities issued alerts for zero-visibility zones on the Delhi-Jaipur and Delhi-Lucknow expressways. Road travel times doubled in affected stretches due to mandatory speed restrictions. Bus operators cancelled overnight services in Punjab and Haryana.
Seasonal fog continues to challenge aviation reliability in the Indo-Gangetic plain each winter. Infrastructure expansion at Delhi and upcoming airports in Noida and Jewar aims to increase resilience. Airlines maintain contingency plans including fleet repositioning and crew extensions during prolonged disruptions.
Global connectivity to India’s northern gateways remains heavily weather-dependent during December and January. Tourism stakeholders monitor recovery timelines for inbound charter groups and cruise passenger fly-cruise combinations. Alternate southern entry points like Mumbai and Hyderabad report normal operations.
