New Delhi, December 29, 2025: IndiGo on Monday cancelled 118 flights across its domestic network, citing a combination of adverse weather conditions and operational constraints, according to information available on the airline’s official website.
Out of the total cancellations, six flights were grounded due to operational reasons, while the remaining services were called off because of bad weather, particularly dense fog affecting flight operations at several airports. The impacted locations included Delhi, Mumbai, Bengaluru, Kochi, Hyderabad, Kolkata, Amritsar, Chandigarh, Jaipur, Dehradun, Indore, Patna and Bhopal, among others.
In a travel advisory issued at 11:20 am, IndiGo said foggy conditions continued to persist across Delhi and multiple airports in northern India, with visibility levels yet to fully improve. The airline warned that the disruption witnessed earlier in the day was likely to extend into the noon hours, resulting in continued delays for some flights.
While acknowledging operational disruptions, IndiGo said flight departures and arrivals were being sequenced carefully to ensure orderly movement and passenger safety. The airline, however, did not specify the exact number of cancellations in its advisory posted on social media platform X.
Flight disruptions due to fog have been recurring since the start of the winter season. Earlier this month, IndiGo had cancelled thousands of flights, including around 1,600 on a single day, following court-mandated changes to pilot duty and rest norms. Since December 10, when the official fog season began, the airline has repeatedly cancelled services, including 67 flights on December 25 and another 57 flights last Saturday, citing poor weather conditions.
The Directorate General of Civil Aviation has designated the period from December 10 to February 10 as the official fog window this winter. During this time, airlines are required to deploy CAT-III compliant aircraft and ensure pilots trained for low-visibility operations are rostered accordingly.
Delhi airport, in its afternoon passenger advisory, said runway visibility had improved and flight operations were running smoothly, though some arrivals and departures could still face disruptions depending on destination-specific conditions. Earlier in the morning, the airport had warned that persistent dense fog had forced operations under CAT-III conditions, leading to delays.
Under CAT-III norms, advanced navigation systems allow aircraft to land safely in extremely low visibility. CAT-III A enables landing with a runway visual range of 200 metres, while CAT-III B permits landings when visibility drops below 50 metres.
