What is the ICAO code for Montgomery airport?

The ICAO code for Montgomery Airport is indeed KMGM, which follows the standardized ICAO coding system used for identifying airports around the world. In this system, the first letter denotes the geographical region and the country where the airport is located. For example, the letter "K" designates the United States, while the "MGM" segment specifically identifies Montgomery Airport in Alabama.

Each ICAO code is unique to its airport, making it easier for air traffic control and pilots to communicate effectively. The codes consist of a four-letter sequence, ensuring that each airport can be distinctly identified regardless of the location. In contrast, the other options listed (KLLQ, KOFF, and KBNA) represent different airports and do not correspond to Montgomery Airport. KLLQ is associated with the lower-tier airport, KOFF serves another location in the US, and KBNA represents Nashville International Airport.
