Which city is represented by the code CLT?

The city represented by the code CLT is Charlotte, North Carolina. Airport codes in the United States typically use three letters that often correspond to a part of the airport's name or the city it serves. In this case, CLT is derived from the first letters of "Charlotte" along with the 'L', which signifies the airport's name, Charlotte Douglas International Airport. This coding system helps travelers identify airports easily and provides a quick reference for airlines and travel plans.

The other options do not align with the given airport code; for instance, Denver, Colorado is represented by the code DEN, Redding, California usesRDD, and Spokane, Washington has the airport code GEG. This shows how the three-letter system follows a pattern based on geographical and airport naming conventions across different regions, further affirming that CLT specifically points to Charlotte.
