Flight Delays at Delhi Airport Due to Technical Glitch in Air Traffic Control System
IndiGo and other major airlines issued travel advisories on November 7, 2025, after a technical issue in Delhi Airport's Automatic Message Switching System (AMSS) disrupted Air Traffic Control (ATC) operations, causing significant flight delays. Controllers are manually processing flight plans while technical teams work to restore the system. Passengers are advised to check for updates from their airlines as authorities prioritize resolving the issue.
On November 7, 2025, Indira Gandhi International Airport (IGIA) in Delhi experienced widespread flight delays due to a technical glitch affecting the Automatic Message Switching System (AMSS), which is critical for Air Traffic Control (ATC) data management. The failure forced air traffic controllers to process flight plans manually, significantly slowing operations and leading to delays for over 100 flights. Major airlines, including IndiGo, Air India, and SpiceJet, issued advisories to passengers, acknowledging the inconvenience and urging travelers to stay in touch with their airlines for the latest updates. Delhi Airport and the Airports Authority of India (AAI) confirmed that technical teams are working to restore the AMSS as a top priority, with close coordination among ATC, airport operator DIAL, and other stakeholders. Passengers were advised to follow airline notifications regarding rescheduled flights and exercise patience as authorities address the disruption. The incident highlights the reliance of modern aviation on automated systems and the cascading impact when such infrastructure fails. While the immediate focus is on restoring normal operations, the event has drawn attention to the need for robust contingency planning in critical airport systems.
