Dense fog in the Delhi-NCR region has affected flight operations over the past few weeks. However, with visibility gradually improving, Delhi airport has seen fewer disruptions since the beginning of 2026.

Air India informed passengers that it is closely monitoring the situation and has taken proactive steps to minimise disruption, advising travellers to check their latest flight status before heading to the airport.

IndiGo, India’s largest airline, issued a separate advisory for Kolkata, stating that low visibility had forced revisions to flight timings. The airline said, "Visibility at Kolkata remains low, and several flights are now operating with revised timings. Some flights may experience delays, and cancellations remain a possibility as the weather shows no signs of improvement."

SpiceJet also issued an advisory for Kolkata, warning that poor visibility and adverse weather conditions could impact all departures and arrivals, as well as consequential flights, at Netaji Subhash Chandra Bose International Airport.

IndiGo further issued travel advisories for several other cities, including Jaipur, Bhopal, Guwahati and Agartala, citing fog-related disruptions. In one advisory, the airline said, "Low visibility and fog over Kolkata, Jaipur, Indore, Udaipur and Bhopal may impact flight schedules. We are closely monitoring the weather and doing our best to get you where you need to be, safely and smoothly," while requesting passengers to regularly check their flight status.

In another update, IndiGo said, "Guwahati and Agartala continue to remain wrapped in chilly winter air and lingering fog this morning. The fluctuating visibility has led to changes in flight schedules, and operations may be slower than usual as conditions evolve."

The airline added that safety and compliance with visibility requirements remain its top priority, stating, "Once the weather settles, operations will gradually stabilise, and flights will depart as planned."
