A brief 45-minute disruption in a major airline software system on Tuesday caused widespread check-in delays at airports. Air India later confirmed that the system had stabilised and flights were operating on schedule. Airlines attributed the slowdown to Amadeus, a widely used software platform in the aviation industry.
Amadeus is one of the world’s largest travel-technology providers, helping airlines manage essential operations such as ticket bookings, check-ins, seat inventory, boarding, and departure controls. Its systems are highly interconnected, so even a short outage can affect flight schedules and passenger processing across airports.
A key component of Amadeus is its Global Distribution System (GDS), which links travel providers—airlines, hotels, rail and cruise operators, and car rentals—with travel sellers like agencies and online booking platforms. The GDS acts as a marketplace for comparing schedules, fares, and availability, while offering tools and APIs for ticketing and real-time updates.
Because Amadeus serves as the digital backbone for airlines and airports, any glitch—especially in check-in modules—can cascade through booking, baggage, boarding, and scheduling operations. High daily traffic, interdependent systems, and its global use mean even short outages can trigger long queues, flight delays, and widespread disruptions at airports worldwide.
