What is the airport code for Salt Lake City, Utah?

The airport code for Salt Lake City, Utah, is SLC. Airport codes are typically based on the name of the city or airport they represent, and they often consist of three letters assigned by the International Civil Aviation Organization (ICAO) or the International Air Transport Association (IATA). In this case, "SLC" stands for Salt Lake City, which is intuitive as it closely matches the city name.

Understanding why other options are incorrect provides context. RIC refers to Richmond International Airport in Virginia, RST is the code for Rochester International Airport in Minnesota, and RDU represents Raleigh-Durham International Airport in North Carolina. None of these codes correspond to Salt Lake City, which confirms that SLC is indeed the correct answer.
