India’s Busiest Airport Back on Track After Glitch Grounds 800+ Flights

Flight operations normalize after ATC system failure Delhi Airport faced widespread disruption on November 7 due to a failure in its Air Traffic Control’s Automatic Message Switching System (AMSS), which handles flight plan data. The glitch led to manual processing of flight plans, causing delays and cancellations across domestic and international routes. The Airports Authority of India (AAI) confirmed that the system has now been restored and operations are stabilizing.

Key highlights:

• Over 800 flights were delayed and 20 canceled due to the AMSS failure  
• The glitch affected pre-departure message flow, forcing airlines to manually submit flight plans  
• AAI assured that flight safety was never compromised, and airborne aircraft were unaffected  
• A technical team from ECIL resolved the issue late Friday night  
• Airline stocks reacted: IndiGo (INGL.NS) fell 2%, SpiceJet (SPJT.BO) dropped 1%, and GMR Airports (GMRI.NS) saw minor volatility  

Looking ahead  
While flight operations are now normal, residual delays may persist as airlines clear backlogs. The incident underscores the need for robust digital infrastructure and contingency planning in aviation.
