Flight tracking website Flightradar24.com recorded 130 delayed flights that morning with average departure delays of approximately 28 minutes. DIAL posted on X that all flight operations continue normally but warned that flights without CAT III compliance might be affected. CAT III compliance allows flights in low visibility.

These include providing timely flight updates, meals for delayed passengers, rebooking or refunds for cancellations, no denial of boarding after timely check-in, baggage help, and fast grievance handling. The Airport Authority of India also issued an advisory about possible flight delays at northern airports due to fog. It asked passengers to stay in touch with airlines through official channels for real-time updates. Travelers were advised to plan for extra time at airport arrival and check-in. This dense fog caused headaches for thousands of travelers but officials continue to monitor and manage the situation carefully.
