Des Moines, Iowa is identified by which airport code?

Des Moines, Iowa is identified by the airport code DSM, which stands for Des Moines International Airport. Each airport is assigned a unique three-letter code by the International Air Transport Association (IATA) to streamline air travel and logistics. DSM is derived from the initials of Des Moines, which helps travelers and airlines easily identify the airport associated with that particular city. This code is used for flight itineraries, baggage tags, and reservation systems, making it an essential component of air travel operations.

In contrast, the other codes mentioned (ELP, DFW, EWR) correspond to different airports located in other cities and regions: ELP represents El Paso International Airport, DFW refers to Dallas/Fort Worth International Airport, and EWR denotes Newark Liberty International Airport. Each of these codes serves to identify their respective airports, but they are not associated with Des Moines, making DSM the accurate choice.
