Which airport code corresponds to Detroit, Michigan?

The airport code that corresponds to Detroit, Michigan, is DTW. This code stands for Detroit Metropolitan Wayne County Airport, which serves as the primary airport for the Detroit area. The choice of DTW aligns with standard airport coding practices, which typically involve utilizing a three-letter designation that often reflects the name of the city or the airport itself. In this case, "D" represents Detroit, with "TW" being selected to differentiate it from other airports.
