Delhi ATC Glitch Causes 200+ Flight Delays in Mumbai, Stranding Passengers for Hours
Delhi ATC glitch halts Mumbai flights: 200+ delays, cancellations leave passengers stranded hours.
A significant technical issue in Delhi’s Air Traffic Control (ATC) system has caused widespread disruption for passengers at Mumbai’s Chhatrapati Shivaji Maharaj International Airport, leading to extensive flight delays and cancellations on November 7, 2025. The problem originated from a malfunction in Delhi’s Automatic Message Switching System (AMSS), crucial for flight planning and data transmission, forcing ATC officials to partially revert to manual operations.
The Airports Authority of India (AAI) confirmed that the glitch slowed down flight coordination not only in Delhi but also affected Mumbai, Bengaluru, Hyderabad, and Pune airports. Over 200 flights faced delays, and several were canceled, leaving terminals crowded with anxious travelers and long queues at check-in and boarding points. Major airlines such as IndiGo, Air India, and SpiceJet reported operational challenges and advised passengers to keep monitoring flight updates.
Social media was abuzz with frustrated passengers sharing their experiences. One user highlighted “210 aircraft in the waiting queue,” while others expressed uncertainty over sudden cancellations and lack of clear communication. Emergency response teams and technical experts have been working relentlessly to restore full system functionality, and partial manual management continues as a temporary solution.

Mumbai airport authorities advised all travelers to contact their respective airlines for the latest status and updates. Officials stressed that the issue is being resolved gradually but acknowledged that cascading effects from the Delhi ATC problem had disrupted the tightly interlinked flight schedules, especially on high-traffic routes like Mumbai to Delhi.
The incident highlights the critical reliance on advanced automation in air traffic control and the significant impact technological failures can have on national aviation operations. An official investigation into the cause of the glitch, possibly linked to malware-induced software overload, is underway to prevent future occurrences.
