What does the airport code RDU represent?

The airport code RDU represents Raleigh/Durham, North Carolina. This code is derived from the names of the two major cities it serves: Raleigh, the capital of North Carolina, and Durham, known for its research and educational institutions. RDU is a primary airport in this region, providing commercial flights and serving as a hub for several airlines.

In contrast, each of the other options corresponds to different airports that have their unique codes. For instance, O'Hare is identified by ORD, West Palm Beach is designated as PBI, and Punta Cana's airport code is PUJ. Understanding these airport codes is crucial for navigating travel itineraries and booking flights accurately.
