Dense fog conditions at Indira Gandhi International Airport in Delhi led to the cancellation of 131 flights on December 16, 2025, disrupting travel plans for thousands of passengers. The fog, characterized by low visibility levels, significantly impacted flight operations, prompting airlines to either cancel or delay numerous scheduled departures and arrivals.
According to the India Meteorological Department (IMD), visibility in the region dropped to as low as 50 meters during the early morning hours, which is well below the minimum requirement for safe flight operations. The IMD had issued a warning about the fog conditions, predicting that the dense fog would persist throughout the day, affecting not only air travel but also road and rail transport in the region.
The impact of the fog was felt across various airlines operating at the airport. Major carriers, including Air India, IndiGo, and Vistara, reported significant disruptions, with many passengers left stranded at the airport. The cancellations were primarily concentrated in the early morning hours, a peak time for domestic and international flights. Passengers were advised to check the status of their flights before heading to the airport, as the situation was fluid and subject to change based on weather conditions.
In response to the disruptions, the airport authorities implemented measures to assist affected travelers. Information counters were set up to provide updates on flight statuses, and airlines were instructed to accommodate passengers on alternate flights where possible. However, the high volume of cancellations led to long queues and increased wait times at the airport, exacerbating the frustrations of travelers.
The dense fog in Delhi is not an isolated incident but part of a broader pattern of winter weather that affects the region annually. Fog formation in northern India is typically associated with a combination of high humidity, low temperatures, and calm winds during the winter months. This phenomenon is particularly prevalent in December and January, when temperatures can drop significantly, leading to increased occurrences of dense fog.
Historically, the impact of fog on air travel in Delhi has been substantial. In previous years, similar weather conditions have led to widespread flight cancellations and delays, prompting discussions about the need for improved infrastructure and technology to mitigate the effects of adverse weather on aviation. The airport has been working on upgrading its Instrument Landing System (ILS) to enhance landing capabilities during low visibility conditions, but challenges remain in fully addressing the issue.
The implications of such weather-related disruptions extend beyond immediate travel inconveniences. The economic impact of flight cancellations can be significant, affecting not only airlines but also the broader travel and tourism industry. Additionally, the disruptions can lead to logistical challenges for businesses that rely on timely air transport for goods and services.
As the winter season progresses, authorities and airlines will continue to monitor weather patterns closely. The IMD has indicated that similar fog conditions may persist in the coming days, raising concerns about further disruptions at the airport. Travelers are encouraged to remain vigilant and stay informed about potential changes to their travel plans.
In conclusion, the cancellation of 131 flights at Delhi’s Indira Gandhi International Airport due to dense fog highlights the challenges posed by seasonal weather patterns in northern India. As the region grapples with the effects of winter fog, stakeholders in the aviation industry are reminded of the need for ongoing improvements in infrastructure and contingency planning to better manage the impact of adverse weather on air travel.
