Southwest Airlines City Codes Practice Test

The city code DFW corresponds to Dallas/Fort Worth, Texas. This code is derived from the name of the Dallas/Fort Worth International Airport, which serves the two metropolitan areas. The airport is one of the busiest in the United States and is strategically located to serve both cities efficiently. Dallas and Fort Worth are often collectively referred to because they are adjacent to each other and together form a major economic hub in Texas. Thus, understanding that DFW relates specifically to this combined area is key for airline operations and travel identification.

The other options do not align with the DFW code, as they represent different cities with distinct airport codes. For example, the cities of Denver, Detroit, and Detroit Lakes each have their unique identifiers that do not overlap with DFW.
