Flight operations at Indira Gandhi International Airport (IGIA) were significantly disrupted due to a technical malfunction in the Automatic Message Switching System (AMSS). This critical system, which feeds flight plan data to Air Traffic Control's Auto Track System (ATS), forced controllers to process plans manually, resulting in delays for over 150 flights. The Airports Authority of India (AAI) confirmed that technical teams are working to restore the AMSS promptly. IGIA is India’s busiest airport, handling over 1,500 daily movements.
