New Delhi | January 13, 2026 

 Passengers traveling from Delhi are set to face significant disruptions from January 21 to 26 as the airspace over the national capital will be closed for nearly two and a half hours daily to facilitate Republic Day preparations. The government issued a NOTAM (Notice to Airmen) on Tuesday, specifying the airspace closure from 10:20 AM to 12:45 PM during the six-day period.

The temporary closure is intended to ensure the safety of aircraft participating in the Republic Day flypast and protect dignitaries during the parade along Kartavya Path. While not all flights will be canceled, most are likely to be rescheduled, rerouted, or delayed. Airlines will also have to manage misconnected passengers, adding to the logistical challenges. Aviation analytics firm Cirium estimates that over 600 flights could be affected during this period, impacting thousands of travelers across India and abroad.

The timing coincides with Delhi’s foggy winter season, which could further complicate flight operations. Passengers are advised to keep their contact information updated with airlines to receive timely notifications of changes. In case of cancellations, airlines typically provide alternative flights or refunds, though fare adjustments are likely due to last-minute changes. Airlines and airport authorities will face the challenge of handling rescheduling and rerouting under near-full operational capacity at Delhi and other major airports.

Experts suggest that earlier announcements could help passengers and airlines better manage the disruptions. Despite the inconvenience, authorities stress that the airspace closure is necessary to ensure a smooth and secure Republic Day parade, which remains one of India’s most significant national celebrations.

 Major Flight Disruptions Expected as Delhi Airspace Closes for Republic Day Preparations

Travelers from Delhi are likely to face significant disruptions as the airspace over the capital will remain closed from January 21 to 26, between 10:20 AM and 12:45 PM daily, due to Republic Day preparations. The NOTAM issued aims to ensure the safety of aircraft during the parade flypast and protect dignitaries along Kartavya Path.

Over 600 flights are expected to be impacted, according to aviation analytics firm Cirium. While not all flights will be canceled, passengers can expect delays, rescheduling, and rerouting, with airlines managing misconnected passengers amid the busy winter travel season.

The closure also coincides with dense winter fog, adding further challenges to flight operations. Passengers are advised to keep contact details updated with airlines to receive notifications. In case of cancellations, alternative flights or refunds will be provided, though fares may rise due to last-minute changes.
