Which city is represented by the airport code GSO?

The airport code GSO represents Greensboro, North Carolina. Each airport code is unique and typically follows the IATA (International Air Transport Association) format, which consists of three letters. In this case, GSO is derived from the city's name, Greensboro, making it a straightforward identification for travelers and airport databases. Recognizing airport codes is essential for efficient navigation and communication in air travel.

The other options pertain to different cities that each have their own distinct airport codes. For instance, Greenville, South Carolina, has the airport code GSP; Huntsville, Alabama, uses HSV; and Hayden, Colorado, is represented by HDN. This differentiation in airport codes ensures clarity and avoids confusion during travel planning and logistics.
