According to the ministry’s 2024‑25 Annual Report, Digi Yatra uses Facial Recognition Technology to allow travellers to pass through various checkpoints at airports without presenting documents[8]. The initiative had been launched at 24 airports, including Delhi, Bangalore, Varanasi, Pune, Kolkata, Hyderabad, Mumbai and others[9], and over 4.14 crore passengers had used the service, with more than 9.23 million downloads of the Digi Yatra app[10]. The report notes that all airports will eventually be covered under the programme[10]. Additional details state that Digi Yatra facilities became operational at 14 AAI airports in 2024, with test operations ongoing at two more (Chandigarh and Srinagar)[11]. By 2026, India plans to expand the platform to every major airport and integrate it with e‑passport systems, enabling passengers to navigate security, boarding and baggage drop using only their facial biometric token.

Vietnam – Long Thanh International Airport’s High‑Tech Systems

Vietnam is constructing the Long Thanh International Airport near Ho Chi Minh City to relieve pressure on the overloaded Tan Son Nhat Airport. A state‑run VietnamPlus report explains that the Vietnam Air Traffic Management Corporation and Airports Corporation of Vietnam performed flight inspection and calibration between 26 September and 29 October to verify the airport’s advanced surveillance systems, which include primary and secondary radars and Automatic Dependent Surveillance–Broadcast (ADS‑B)[12]. These systems were confirmed to meet International Civil Aviation Organization (ICAO) and European standards[12], and experts from the Czech Republic praised the technical proficiency of Vietnamese personnel. The article notes that Long Thanh International Airport is expected to begin commercial operations in 2026[13]. Complementing the airport’s high‑tech infrastructure, a Xinhua report states that Ho Chi Minh City plans to complete three metro lines connecting Tan Son Nhat International Airport, the city centre and Long Thanh by 2030[14]. The combination of advanced surveillance technology and integrated rail links underscores Vietnam’s ambition to deliver a modern, efficient air‑travel gateway by 2026.
