However, the carrier later confirmed that the system had been fully restored and that operations had returned to normal, with all flights now running according to schedule.

Similar Tech Issue Last Month

Last month, more than 400 domestic and international flights were delayed when a technical glitch in the Automatic Message Switching System (AMSS) disrupted operations at Delhi’s Indira Gandhi International Airport.

Multiple airlines, including Air India, IndiGo and SpiceJet, were affected, leading to longer queues and slower processes at the airport.

The issue was traced to the IP-based AMSS system, prompting a review by the Ministry of Civil Aviation and senior officials from AAI and ANS. During the disruption, air traffic controllers had to manually prepare flight plans, leading to delays.
