airspace restriction

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.

New Delhi, India: Flight operations across several Indian carriers were disrupted on Tuesday after volcanic ash from Ethiopia’s Hayli Gubbi eruption drifted toward major West Asia and India-bound air corridors. Airlines including Air India, Akasa Air and IndiGo cancelled or rerouted multiple flights as the Directorate General of Civil Aviation (DGCA) issued an urgent advisory enforcing strict avoidance of ash-affected airspace. The DGCA directed airlines to steer clear of regions and flight levels identified as contaminated by volcanic ash. The regulator also instructed carriers to reassess flight plans, fuel requirements and alternates, and to file immediate reports of any suspected ash encounters. The advisory highlighted the risk to aircraft engines and airframes, and asked operators to conduct additional inspections for any aircraft that may have flown near the affected zones. Airports were simultaneously ordered to check runways, aprons and taxiways for possible ash contamination and initiate cleaning procedures if required. Air India cancelled 11 flights over the past 24 hours, stating that precautionary checks were needed on aircraft that might have traversed areas close to the ash plume. The airline said it was monitoring volcanic-ash advisories in coordination with international aviation agencies and had not observed any major operational impact beyond temporary cancellations. Akasa Air suspended several India–Gulf flights, including services to Jeddah, Kuwait and Abu Dhabi, citing the need to avoid ash-affected airspace over the Arabian Peninsula. The airline offered full refunds and complimentary rebooking for passengers scheduled to travel on 24 and 25 November. IndiGo reported multiple cancellations as well, noting that its operations team was adjusting routes in real time based on ash-movement maps issued by global meteorological centres. At least six flights including services from Mumbai and southern metros were grounded as a precaution. Volcanic ash can severely damage aircraft by melting inside engines, clogging ventilation systems and affecting sensors. Following ICAO protocols, Indian carriers have shifted flight paths and temporarily halted services operating along westbound routes that intersect the plume’s trajectory. Although the ash cloud was observed at high altitudes reducing the likelihood of direct impact on surface visibility, aviation authorities stressed that even small concentrations can be hazardous for high-altitude jet operations. Meteorological agencies indicated that the ash plume continued its eastward movement toward China after passing over northern India. Airlines said normal operations would resume once updated advisories confirm the clearing of affected corridors. Indian regulators and carriers remain on heightened watch, treating the event as a significant international air-safety incident requiring continuous monitoring.
