Delhi Airport Flights Returning to Normal After Major Tech Glitch
New Delhi, November 8, 2025 – Flight operations at Delhi’s Indira Gandhi International Airport are steadily returning to normal after a notable technical issue disrupted air traffic control systems for over 24 hours. The disruption, stemming from a glitch in the Automatic Message Switching System (AMSS) – a critical component supporting flight planning – began late Thursday and caused widespread delays and congestion.
The Airports Authority of India (AAI) confirmed late Friday that the AMSS systems were ”up and functional now,” though cautioned that “some backlogs” may lead to continued delays in automated operations. ”The situation will be normal soon,” the AAI stated in an official release.
The AMSS outage impacted the flow of flight plans, forcing air traffic controllers to revert to manual procedures. This affected both domestic and international flights, including a nearly two-hour delay for an ITA Airways flight to Rome and a delay of over an hour for a virgin Atlantic flight to London. Airlines, including Air India Express, deployed staff to manually prepare flight plans in response.
Budget carrier IndiGo issued an advisory stating that normal operations were being “progressively restored” at Delhi Airport and other impacted airports in the northern region. Though, the airline advised passengers to check the status of thier flights, anticipating potential adjustments to departure and arrival timings. “As flight operations stabilise, delays and terminal-side congestion may continue for some time,” IndiGo said.
Delhi airport officials confirmed on X (formerly Twitter) that the technical issue affecting the AMSS was ”gradually improving” and that all concerned authorities were “working diligently to minimise any inconvenience caused.” Passengers are urged to confirm flight updates with their respective airlines.
The AMSS supplies data to the Auto Track System (ATS) used for generating flight plans, and its failure caused significant disruption to the air traffic control process.
