Dense fog conditions across large parts of north India have significantly disrupted air travel, forcing multiple airlines to issue advisories warning passengers of possible flight delays and cancellations. As winter conditions intensify, low visibility has affected airport operations, particularly in and around Delhi, leading to cascading delays across airline networks. The latest dense fog flight disruption news highlights how seasonal weather patterns continue to challenge aviation operations during peak travel periods.
On Thursday morning, SpiceJet issued a travel advisory cautioning passengers about disruptions caused by poor weather and dense fog in Delhi. The airline stated that all departures, arrivals and consequential flights could be impacted due to reduced visibility. Passengers were advised to check their flight status on the airline’s website before heading to the airport, underlining the uncertainty surrounding operations during foggy conditions.
Similarly, Air India warned that dense fog conditions expected over the next few days could result in low visibility, affecting flight operations not only at its primary hub in Delhi but also at several airports across northern and eastern India. The airline noted that disruptions at these airports could have a cascading effect across its entire network, leading to extended delays and occasional cancellations.
In an advisory issued earlier, Air India urged travellers, especially during the busy holiday season, to remain vigilant and check flight status updates before travelling. The airline said it had undertaken advance operational planning, enhanced ground coordination, and other proactive measures to minimise fog-related disruptions. Despite these efforts, Air India acknowledged that sudden cancellations or prolonged delays could still occur during periods of extremely dense fog.
To support passengers during such disruptions, Air India highlighted its FogCare initiative. Under this programme, passengers on flights likely to be affected receive advance alerts on their registered mobile numbers. The initiative also allows travellers the flexibility to change flights without additional charges or opt for a full refund without penalty. The airline reiterated that passenger and crew safety remains its highest priority while managing challenging weather conditions.
IndiGo, India’s largest airline by market share, also issued a travel advisory earlier in the week, stating that low visibility and fog over Chandigarh had affected flight schedules. The airline said it was closely monitoring weather developments and advised passengers to stay updated through its website or mobile app. IndiGo assured customers that its teams were available to provide assistance and minimise inconvenience during the disruption.
The north India fog latest news has also drawn attention to deteriorating air quality levels, particularly in the national capital. According to data from the Central Pollution Control Board’s Sameer app, Delhi’s Air Quality Index (AQI) stood at 356, categorised as very poor, as of 6:00 am on Thursday. Poor air quality combined with dense fog has further reduced visibility, compounding challenges for aviation and surface transport.
In response to the worsening pollution levels, the Delhi government has announced a series of strict anti-pollution measures. These include a shift to hybrid work models, a ban on vehicles carrying construction material, and mandatory Pollution Under Control (PUC) certificates for vehicles entering the national capital. These steps aim to curb emissions and improve air quality during the critical winter period.
The impact of dense fog is not limited to aviation alone. Road and rail transport across parts of north India have also experienced delays, affecting daily commuters and long-distance travellers. However, flight disruptions tend to have a wider ripple effect, as delays at major hubs like Delhi can impact schedules nationwide.
The recurring issue of winter fog and low visibility highlights the importance of advanced planning and coordination between airlines, airport authorities and meteorological agencies. Airlines continue to invest in improved landing systems, crew training and passenger communication tools to reduce the impact of fog-related disruptions. Nevertheless, extreme weather conditions remain a significant operational challenge.
Passengers are being advised to remain patient and cooperative during this period of disruption. Airlines have emphasised that while every effort is being made to maintain schedules, safety considerations take precedence over on-time performance. Travellers are encouraged to allow extra time, stay informed through official channels, and make use of flexible rebooking options where available.
In conclusion, dense fog across north India has once again disrupted flight operations, prompting airlines to issue advisories and implement contingency measures. With Delhi flights delayed today due to low visibility and AQI levels remaining very poor, the situation underscores the combined impact of weather and pollution on daily life. As reflected in top news headlines weather India, authorities and airlines continue to manage the challenges while urging passengers to stay informed and prepared during the winter fog season.
