Which code corresponds to American Airlines?

• A. ACA
• B. AFR
• C. AAL
• D. AMF

Answer: (C)

In aviation, airlines are identified in different coding systems. The two main ones are IATA, which uses a two-letter code (often seen on tickets and baggage tags), and ICAO, which uses a three-letter code for flight operations and air traffic control. For American Airlines, the ICAO three-letter designator is AAL, while the IATA two-letter code is AA. The three-letter code is the one used in many operational contexts, like flight plans and ATC communications.

So, the code that corresponds to American Airlines in the ICAO system is AAL. The other three-letter codes point to different airlines (for example, ACA is Air Canada, AFR is Air France), so they don’t match American Airlines.
