(DELHI, INDIA) Nearly 700 flights were delayed at Indira Gandhi International Airport on November 7, 2025, as a major technical glitch in the Air Traffic Control system’s Automatic Message Switching System (AMSS) disrupted operations across all airlines and left thousands of travelers facing a day of uncertainty. The disruption, confirmed by the Airports Authority of India (AAI), stemmed from a malfunction in AMSS, which feeds flight data into the Auto Track System (ATS). With the system down, air traffic controllers had to process flight plans manually, a situation that quickly bred congestion and widespread delays across the aviation hub and beyond.
The effects were swift and far-reaching. Based on data from Flightradar24, nearly 700 flights were delayed at Delhi, with additional delays reported at Mumbai airport due to the same technical issue. The disruption sent ripple effects through the region, forcing airlines to redraw schedules on the fly and prompting travelers to shelter in airports or seek alternate routes. Officials stressed that the delays were not caused by weather or scheduling but by a technical failure inside the data-handling backbone that supports real-time flight movements.
Across the board, airlines acknowledged the seriousness of the problem and urged passengers to stay informed. Air India issued a statement saying,
“Our cabin crew and on-ground staff at the airport are extending immediate assistance to reduce passenger inconvenience. We request you to check your flight status… before heading to the airport.”
IndiGo’s social media posts reflected the same urgency, with the carrier stating,
“We understand that extended wait times both on the ground and onboard may cause inconvenience. Our teams are working hard to make your experience as smooth as possible.”
SpiceJet joined the chorus, advising travelers to “keep a check on flight status” through its website. Each message underscored the practical reality on the ground: gate changes, extended waiting times, and a need for travelers to monitor communications from both their airlines and the airport.
The human dimension of the disruption quickly came into focus. A passenger tweeting from IndiGo’s X page described a harsh, moment-by-moment reality:
“At the Delhi airport, the flyers are made to wait on board the plane for more than 4 hours. Delays are understandable, at this moment you can rather cancel the flight and spare them the misery.”
The experiences described by travelers on social media and in passenger reports included requests for refunds due to missed connections, concerns about communication gaps, and a surprising shortage of snacks for stranded passengers. Many described being kept on planes for hours or left in limbo at gates that shifted in response to the evolving operational picture, all a direct consequence of the AMSS failure and the manual processing it necessitated.
The AAI, as the custodian of India’s critical airport infrastructure, provided a crisp explanation of the technical underpinnings of the disruption. “Flight operations at Delhi Airport are experiencing delays due to a technical issue in the Automatic Message Switching System (AMSS), which supports Air Traffic Control data. Controllers are processing flight plans manually, leading to some delays. Technical teams are working to restore the system at the earliest,” the agency stated. The message was echoed in an advisory from Delhi Airport itself:
“The inconvenience is deeply regretted. Passengers are advised to stay in touch with their respective airlines for the latest updates.”
Taken together, these statements laid bare a moment when the airspace and the ground teams had to operate without the automated cues that typically keep schedules tight and predictable.
As the day wore on, officials reported that technical teams were actively working to resolve the AMSS glitch, with operations gradually returning to normal by late afternoon. The restoration timetable, however, remained uncertain, and the sense of dislocation lingered for many travelers attempting to connect to other destinations or to return home. For the broader public watching Delhi’s air traffic to gauge the severity of the incident, the episode highlighted both the fragility and resilience of a modern aviation system that depends on a dense weave of technologies, human intervention, and real-time communications.
The disruption drew attention not only to the operational impact but also to the information flow surrounding it. Passengers and families affected by the delays needed clear guidance about refunds, rebooking options, and the likelihood of additional complications should the AMSS issue persist. Airlines urge caution and patience, while authorities stressed that the situation was being handled with urgency, even as the system’s breakdown underscored the dependence on digital tools that can falter without warning. In this moment, the Aeropuerto de Delhi, the hub at the heart of India’s air travel network, stood as both a symbol of rapid connectivity and a reminder of how a single technical fault can ripple through a nation’s travel plans.
For those navigating the day’s challenges, the practical guidance remained consistent: check flight status directly with the airline before heading to the airport, be prepared for extended waiting times, possible gate changes, and delays in check-in and boarding, and seek on-ground assistance from airline staff if stranded or facing missed connections. The situation also prompted renewed emphasis on contingency planning—how travelers should manage connections through other airports if necessary, and how families and business travelers alike should budget extra time for unexpected disruptions.
In the weeks that followed, observers noted that this was not an isolated setback but part of a broader pattern in which the Delhi airport community had recently faced a sequence of operational strains. The incident occurred as the airport had already been contending with other disruptions in the same week stemming from GPS spoofing incidents and wind shifts that had challenged air traffic operations. That context did not diminish the immediate urgency of the AMSS failure, but it did frame the episode as part of a larger narrative about resilience and adaptation within India’s busiest aviation corridor.
From a policy and governance perspective, the incident underscored the importance of robust redundancy and rapid response protocols for critical flight-data systems. The AMSS is central to how data flows from the cockpit to the control tower, and a glitch here translates into real-world consequences for passengers, crews, and airport staff alike. Analysts and industry observers will be watching closely how authorities accelerate system restoration, what measures are put in place to prevent a recurrence, and how airline partners adjust their own operations in the face of continued uncertainty about the reliability of core data streams.
Meanwhile, the human consequence remains at the forefront of the day’s reporting. Families, travelers, and crews shared stories of interrupted plans, the emotional toll of long waits in crowded terminals, and the challenge of coping with a sudden change in travel plans. The phrase “delay” takes on a heavier meaning when it involves hours on end and the emotional strain of unplanned layovers. With the AMSS issue affecting all major airlines—Air India, IndiGo, SpiceJet, and others—the disruption exposed the interconnected nature of India’s aviation ecosystem, where a single technical fault can cascade through a network of routes, airports, and service providers.
As the afternoon gave way to evening, some signs of stabilization emerged, with officials reporting that operations were returning to a more typical rhythm in limited pockets of the airport complex. Yet the episode left a lasting impression on passengers who had to navigate a day of profound uncertainty. The AMSS outage that triggered the widespread delays at the Aeropuerto de Delhi will be studied in the weeks ahead as officials review response times, contingency planning, and the practicalities of maintaining smooth operations in the face of unexpected technical failures. The road to full restoration is likely to be incremental, with incremental improvements feeding into a broader corrective effort designed to minimize the risk of future disruptions.
In the immediate term, travelers were urged to remain vigilant about status updates from their airlines and to stay connected with airport advisories as information continued to evolve. The emphasis on direct communication—airlines telling passengers to verify flight status before heading out, and the airport offering apologies and guidance—reflected a concerted attempt to calm nerves while the technical fix was pursued. The episode also sparked broader discussions about passenger rights in the event of prolonged delays, including the possibility of refunds for missed connections and accommodations or meal vouchers where appropriate—issues that airlines and regulators will likely revisit in the wake of the AMSS incident.
If there is a silver lining to the day’s disruptions, it is the reaffirmed commitment from the aviation community to maintain safety and manage operational risk in a high-stakes environment. Even as the AMSS was restored and flights gradually returned to their normal cadence, the days ahead would test the industry’s ability to translate a technical setback into a learning opportunity, to strengthen the resiliency of the Aeropuerto de Delhi, and to reassure travelers that the system will fare better the next time it is confronted with a fault in the data backbone that keeps air travel running.
For those seeking the latest authoritative updates, the Airports Authority of India has continued to provide ongoing briefings and status reports. Passengers and observers can consult the official channels for the most current information on flight operations at Delhi Airport as the AMSS issue is resolved. The incident’s pragmatic lesson is clear: when the flow of flight data falters, the human footprint—pilots, controllers, ground crew, and passengers—becomes the measure of how well a system can weather a disturbance and return to normal service.
In a landscape where speed, precision, and reliability define the airline experience, this disruption placed a clear spotlight on the fragility that can accompany even the most advanced infrastructures. Yet it also highlighted the dedication of those working to restore normalcy: the technical teams racing against the clock, the airline staff guiding anxious passengers, and the decision-makers tasked with preventing a recurrence. The AMSS fault, the delays de vuelos, and the protests of frustration from those left waiting are not just statistics. They are lived experiences that underscore the reality of modern air travel in a country with one of the world’s busiest aviation networks, and they will continue to shape how the sector communicates, compensates, and protects the traveling public in the weeks and months ahead. For now, the priority remains clear: reestablish a reliable data stream, minimize future interruptions, and ensure that when the next glitch arises, the system can absorb it with less disruption to the daily lives of travelers who rely on the Aeropuerto de Delhi to connect them with the world.
