Specific List of Flights Cancelled Today, December 18, 2025
Last Updated: December 18, 2025
Several domestic flights were cancelled across India on December 18, 2025, as dense winter fog combined with airline operational constraints disrupted schedules. Visibility dropped below 150 metres at major northern airports, including Delhi and Chandigarh, forcing airlines to cancel or reschedule multiple services.
In addition to weather-related challenges, IndiGo continues to operate under a DGCA-mandated 10% winter schedule cut, leading to cancellations even on routes not directly affected by fog.
Live Updates: Flight Cancellations on December 18, 2025
Status: Ongoing updates as airlines revise schedules due to fog and operational constraints.
Dense fog reduces visibility below 150 metres at Delhi (DEL) and Chandigarh (IXC), leading to multiple early-morning flight cancellations.
IndiGo confirms cancellation of additional flights as part of its 10% winter schedule reduction ordered by the DGCA.
Airlines advise passengers to check flight status before heading to airports and use free rebooking or refund options where available.
Why Flights Are Being Cancelled Across India Today
Today’s disruptions are being driven by two overlapping factors: dense fog across North India and reduced airline capacity. Airports such as Delhi (DEL) and Chandigarh (IXC) are particularly vulnerable during early morning hours, when fog intensity peaks and flight crew duty limits are exceeded due to delays.
The 10% Schedule Cut: Why IndiGo Is Under Fire
Earlier this month, IndiGo cancelled more than 1,000 flights in a single week, prompting regulatory intervention. The Directorate General of Civil Aviation initially proposed a 5% reduction, but doubled it to 10% on December 9 after operations failed to stabilize.
The primary issue is a pilot availability crunch triggered by stricter Flight Duty Time Limitation (FDTL) norms. As a result, even flights scheduled on clear-weather days may be cancelled as the airline scales back operations. Travelers are advised to regularly check IndiGo flight status updates.
Air India’s “FogCare”: A Safety Net for Travelers
While IndiGo faces regulatory pressure, Air India has activated its winter FogCare policy. Using 24-hour weather forecasts, the airline proactively flags flights likely to be affected by fog and informs passengers via SMS or WhatsApp.
Affected travelers can reschedule within 72 hours at no extra cost or opt for a full refund, allowing them to avoid long waits at fog-affected terminals. Learn more about Air India passenger policies.
