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.
![Washington, United States: A United Airlines flight bound for Guatemala City made an emergency diversion to Washington Dulles International Airport after a passenger allegedly attempted to open a cabin door at cruising altitude and assaulted another traveler, according to air traffic control communications and federal authorities. The incident involved United Airlines Flight 1551, operated by a Boeing 737 MAX 8, which departed from Newark Liberty International Airport on Thursday evening carrying 145 passengers and six crew members. The aircraft had been en route to Guatemala City when the crew declared an emergency and diverted to Washington Dulles International Airport in Virginia. According to audio between the flight crew and air traffic controllers, the pilot informed controllers that the disruptive passenger attempted to open Door 2L while the aircraft was cruising at approximately 36,000 feet. The pilot also reported that the passenger later assaulted another individual onboard. During the exchange, the tower asked the crew which door the passenger had attempted to access. The pilot responded: “Door 2L at 36,000 feet and then [the passenger] assaulted a fellow passenger.” When controllers asked whether there were any injuries onboard, the pilot replied: “Not to our knowledge.” The aircraft landed safely at Washington Dulles at approximately 8:38 p.m. local time. Law enforcement and emergency personnel met the aircraft upon arrival. The FBI later confirmed that agents responded to the incident at the airport, although the agency did not immediately release additional details regarding the passenger’s identity, possible charges, or whether the individual was taken into federal custody. Flight tracking data showed the aircraft remained airborne for a period before diverting toward the Washington region instead of continuing south toward Guatemala. The diversion temporarily disrupted the scheduled international service but no injuries among passengers or crew were officially reported. United Airlines had not issued a detailed public statement at the time of publication regarding the circumstances surrounding the diversion or the status of the passenger involved. Federal authorities are expected to review crew reports, passenger statements, and onboard evidence as part of the investigation.](https://aviationtoday.in/wp-content/uploads/2026/05/AVIATION-TODAY-UNITEDV-AIRLINES-RUDE-PASSENGER-768x432.jpg)
