IATA and ICAO codes are widely used in the aviation industry for referencing airports and airlines, providing a quick and straightforward way to communicate and reference information. The IATA Airline Codes (Two Letter) and ICAO Code (Three-Letter) standards are defined by International Air Transport Association (IATA) and International Civil Aviation Organization (ICAO), respectively. These codes are used for commercial purposes such as airline ticketing, baggage tags, and boarding passes, while ICAO codes are used for official purposes like ATC communication and flight plans. The IATA and ICAO Codes API provides a simple and easy-to-use Restful API that allows users to get information about any airline, such as its Name, IATA, and ICAO codes, and also provides a list of 750+ registered airlines across the world. The API is ideal for applications such as flight booking websites, flight tracker applications, airline databases, mobile games and applications, and travel websites. It follows REST API standards, making it easy to integrate with various languages and platforms. With its extensive database, seamless integration, speed, and benefits like reduced latency and improved performance, the IATA and ICAO Codes API is an essential tool for developers building aviation-related applications.
