What is Baltimore's ICAO code?

Baltimore's ICAO code is KBWI, which stands for Baltimore/Washington International Thurgood Marshall Airport. The "K" at the beginning of the code indicates that it is located in the United States, as this is the prefix for all U.S. airports. Following the "K," the letters "BWI" specifically designate this particular airport, allowing for differentiation from others in the region.

The other codes listed represent different airports: KATL refers to Hartsfield-Jackson Atlanta International Airport, KAMA is the ICAO code for Rick Husband Amarillo International Airport, and KADW is assigned to Andrews Air Force Base. Each of these codes begins with "K" but designates a different location, thereby highlighting the importance of these unique identifiers in air traffic and aviation management.
