IndiGo Flight Status December 17: Dense Fog Triggers Fresh Cancellations at Major Indian Airports

NEW DELHI December 17, 2025 – Flight operations for India’s largest carrier, IndiGo, remained significantly disrupted on Wednesday, December 17, as a thick blanket of winter fog descended across North and East India. While the airline is gradually recovering from a recent operational crisis, the adverse weather conditions have forced the cancellation of numerous flights, leaving thousands of passengers stranded or facing long delays.

The Weather Impact

Early on Wednesday morning, IndiGo issued a travel advisory via social media platform X (formerly Twitter), warning passengers of reduced visibility. “As the morning approaches under misty winter skies, fog is predicted across parts of North and East India, which may lead to reduced visibility and a slower pace of flight movements,” the airline stated.

The most severe impact was felt at Delhi’s Indira Gandhi International Airport and Chennai Airport, with cascading effects reaching Hyderabad, Mumbai, and Kolkata.

What Passengers Need to Know

IndiGo has activated its “Plan B” options for affected travellers. If your flight is cancelled or delayed by more than the stipulated time, you are eligible for:

1. A Full Refund: Passengers can opt for a complete refund of the ticket fare.
2. Alternate Flights: Rebooking on an alternative flight at no additional cost, subject to availability.

Travel Tip: Before leaving for the airport, passengers are strongly advised to check their real-time flight status on the IndiGo website or mobile app. The airline also noted that foggy conditions are affecting road traffic, so commuters should factor in extra time to reach the airport.

Legal and Operational Context

The timing of today’s disruptions is particularly sensitive for the airline. A Public Interest Litigation (PIL) is scheduled to be heard today (December 17) in the Delhi High Court, seeking higher compensation for passengers affected by the widespread cancellations seen earlier this month.

While the airline maintains that safety is its top priority and that ground teams are working to manage schedules, the combination of seasonal weather and operational pressure continues to test the patience of domestic flyers this winter.
