Delhi, India: Air traffic in and out of Indira Gandhi International Airport (IGIA) is facing significant disruption this week as temporary airspace closures come into force ahead of the 77th Republic Day celebrations. Authorities have issued formal restrictions that are expected to affect hundreds of scheduled flights between January 21 and January 26. Under Notices to Airmen (NOTAMs) issued by the Airports Authority of India (AAI) and associated civil aviation agencies, the airspace over Delhi will be closed to commercial departures and arrivals daily between 10:20 a.m. and 12:45 p.m. (IST) for a duration of 2 hours 25 minutes. The restrictions are designed to facilitate military flypast rehearsals, parade drills and associated aerial security procedures ahead of the Republic Day parade. According to aviation analytics firm Cirium, more than 600 flights are likely to be delayed, rescheduled or cancelled over the six-day period due to the closure coinciding with one of IGIA’s busiest scheduling windows. Airlines have warned of unpredictable movement patterns throughout the affected window, with adjustments to flight departures and arrivals increasingly likely during the restricted hours. Passengers travelling to or from Delhi are being urged to check flight status updates directly with carriers before their scheduled departure. On January 19, well ahead of the formal restriction dates, three Srinagar–Delhi flights were cancelled as preliminary rehearsals triggered temporary shutdowns of critical airspace corridors, highlighting the cascading impacts of the restrictions. Regional disruptions are also emerging. On the Delhi–Pantnagar route, early-morning services were cancelled due to the imposed no-fly zone, with airlines offering rebooking or refunds to affected passengers. Similarly, two Air India flights operating between Nagpur and Delhi have been cancelled through January 26 as operators adjust schedules in light of the closure. The closures coincide with peak winter weather conditions in the national capital region. Dense fog and poor visibility have already contributed to flight delays and cancellations at IGIA and other airports in northern India in recent days. A travel advisory issued on January 17 by Delhi Airport officials highlighted that persistent fog coupled with heightened Republic Day security measures could create compounded challenges for passengers and airlines. The airspace restrictions form part of an integrated national security plan for Republic Day, which also includes extensive no-fly zones and road traffic curbs in central Delhi on rehearsal and parade days. Delhi Police and civil aviation authorities have coordinated the measures to balance security needs with transport continuity.
