Which city's airport is identified by the code TUS?

The airport code TUS is associated with Tucson International Airport, which is located in Tucson, Arizona. Airport codes are typically three-letter identifiers assigned by the International Civil Aviation Organization (ICAO) or the International Air Transport Association (IATA). In this case, TUS specifically signifies Tucson, allowing travelers and aviation professionals to quickly identify the destination or departure airport.

Other options present airports from different locations, which do not share the TUS designation. For instance, Miami International Airport has the code MIA, Tampa International Airport uses TPA, and Johnson City's airport typically does not have a three-letter IATA code that would correspond to TUS. This highlights how each airport has a unique identifier that assists in avoiding confusion and ensuring precise navigation within the aviation system.
