New Delhi, May 12 -- At least 97 flights were cancelled and over 150 were delayed in Delhi on Sunday as the Indira Gandhi International (IGI) Airport continued to reel from the closure of 32 airports in western and northern states of India due to ongoing hostilities with Pakistan, even as an agreement to stop all military action was reached on Saturday. According to airport data, 96 of the 97 flights were domestic, and of these 44 were arrivals and 52 were departures. The other one was the only international flight, to Tel Aviv in Israel, to be cancelled. "The flights impacted included 44 arrivals and 52 departures. Only one International flight was cancelled, which was flight AI-139 - to Tel Aviv," said an airport official aware of the matter. According to flight tracking website FlightRadar, over 150 flights were also delayed on Sunday, with an average delay time of 15 minutes. A day earlier, 60 flights were cancelled and over 200 were delayed. On Sunday, as many as 32 airports were shut across the country due to security reasons. These are airports primarily in the north, northwest and the western part of the country, close to the Pakistan border. The closure will be effective from "May 9, 2025, to May 14, 2025 (which corresponds to 0529 IST on 15th May 2025), due to operational reasons," the Directorate General of Civil Aviation (DGCA) said in a release on Saturday. The Delhi airport is the biggest one still operational in northwest India. Airports in a few nearby cities, such as Dehradun, Lucknow, and Jaipur, among others, are also functioning as of now. Meanwhile, security continued to remain high at the Delhi airport, with additional checks being carried out for each passenger. Airlines have also been urging passengers to reach the airport at least three hours before their scheduled time of departure. In an advisory on Sunday, the Delhi airport said, "Delhi airport is operating normally. However, due to changes in airspace dynamics and increased security measures, some flight schedules and security checkpoint processing times may be affected." On Saturday, the Central Industrial Security Force (CISF) said it was mandated to provide additional security at airports in the country, including Delhi. Ajay Dahiya, DIG (chief PRO), CISF, said they had responded immediately and resumed oversight over cargo and baggage operations. "CISF will oversee operations and the security staff of airport operators. Directives also authorise CISF to perform random checks," he said....
