Which of the following airlines is represented by the ICAO code 'AAL'?

The ICAO code 'AAL' is the designator assigned to American Airlines. ICAO codes, which stand for the International Civil Aviation Organization codes, are unique four-letter codes used to identify airlines and other aviation entities worldwide. Each airline has a specific code that allows for clear communication and identification in the aviation industry.

American Airlines, being one of the major carriers in the United States, is represented by this designation, which ensures its operations are easily recognized within air traffic control and other regulatory frameworks. In contrast, other airlines, such as Delta Airlines, United Airlines, and Republic Airways, each have their own distinct ICAO codes that do not coincide with 'AAL'. For instance, Delta Airlines is represented by the code 'DAL', United Airlines by 'UAL', and Republic Airways, which operates regional services under different brands, is identified by a separate designator. Therefore, understanding the assignment of ICAO codes is crucial for distinguishing among various airlines.
