Delhi airport operations to normalise soon as technical issue resolved after 800 flight delays

The Air Traffic Control technical glitch at the Delhi airport has been resolved after almost 48 hours of disruptions, which affected more than 800 flights at one of the country's busiest airports.

The Airports Authority of India (AAI) issued a statement on Friday evening stating that the technical issue in the  Automatic Message Switching System (AMSS), responsible for managing aircraft by the Air Traffic Control (ATC), has been resolved after a multi-agency team visited the site and carried out key review works.

"The issue was detected on November 6, 2025, in the IP-based AMSS system. Immediately, the review meeting was conducted by the Secretary, MoCA, with Chairman AAI, Member ANS, and other officials, and



necessary directions were given to address the issues," it said.

"The original equipment manufacturer was engaged, and additional staff were deployed to manually process Flight Plans for the Air Traffic Control system to ensure uninterrupted and safe air traffic operations immediately," it added.

The AAI said officials are present on the site and the AMSS has now been made functional, but due to backlogs flight schedules, delays will persist for some time and flight operations will return to normal soon.

"The AMSS systems are up and functional now. Due to some backlogs, there may be some delays in the normal functioning of automated operations, but the situation will be normal soon," the statement read.
