In large airports, there are different sets of FIDS for each terminal or even each major airline. FIDS are used to inform passengers of boarding gates, departure/arrival times, destinations, notifications of flight delays/flight cancellations, and partner airlines, et al.

Flight information, often transmitted via ADS-B (Automatic Dependent Surveillance-Broadcast) and processed through Global Distribution Systems (GDS), is used by a wide array of stakeholders to ensure safety, efficiency, and transparency. Air Traffic Control (ATC) uses real-time data to maintain safe separation between aircraft and manage the flow of traffic into busy airports. Airlines use this data to track their fleet, optimize fuel consumption, and manage crew scheduling. For the general public, flight information is utilized through apps like Flightradar24 to track the arrival of loved ones or check for delays. Ground handling crews at airports rely on precise "Estimated Time of Arrival" (ETA) data to ensure that baggage handlers, fueling trucks, and gate agents are ready the moment a plane touches down. Furthermore, historical flight data is analyzed by safety boards to investigate incidents and by urban planners to study noise pollution patterns around metropolitan areas. In the digital age, this data has become a commodity, sold to hedge funds and travel agencies to predict market trends and adjust pricing dynamically based on demand and route popularity.
