The first gateway for travelers visiting North Carolina's capital, Raleigh, is Raleigh–Durham International Airport (airport code RDU). As the name suggests, this airport is located between the cities of Raleigh and Durham and serves as a hub for the entire Research Triangle area.

RDU is of medium size but is recognized as one of the top airports in the Southeastern United States in terms of operational efficiency and service quality.

During World War II, Raleigh–Durham International Airport was used as a training ground for the U.S. Air Force, and after the war, it was converted into a civilian airport responsible for North Carolina's air travel. At that time, there was only one runway and a small terminal building, but as Raleigh, Durham, and the Research Triangle area rapidly grew, the airport was steadily expanded. It now covers approximately 5,000 acres and sees an average of over 400 flights per day.

Currently, RDU has two main terminals. Terminal 1 is primarily used by Southwest Airlines, while Terminal 2 is utilized by major airlines such as American Airlines, Delta, United, JetBlue, Air Canada, and Frontier. Terminal 2, completed in 2011, is a modern building with a sleek design combining glass and steel. It is praised for its ample natural light, spacious seating areas, and clean facilities.

RDU is the largest international airport in North Carolina, with both domestic and international routes steadily expanding. Currently, there are direct flights to major cities such as New York, Chicago, Atlanta, Dallas, Charlotte, and Washington D.C. Internationally, it connects to London Heathrow (LHR), Paris Charles de Gaulle (CDG), Toronto in Canada, and Cancun in Mexico. Notably, it serves as a hub for American Airlines and Delta Airlines, making it convenient for connecting flights to Europe and South America.

The airport services are also meticulously managed. Terminal 2 features popular coffee brands and local eateries, among which 'La Farm Bakery' is a local bakery in North Carolina that is very popular among travelers. Additionally, the airport offers free Wi-Fi, charging stations, a nursing room, a pet relief area, and meditation spaces. The shopping area has a good mix of local specialties, souvenirs, and electronics stores, making it a pleasant place to spend time before or after flights.

Accessibility to the airport is excellent. It takes about 15 minutes from downtown Raleigh and about 20 minutes from Durham. For those driving, the I-40 highway runs right next to the airport, making travel very convenient. The airport has well-defined short-term and long-term parking areas, and a shuttle bus connects the parking lot and terminals every 10 minutes. If you need to rent a car, you can head to the 'Rental Car Center' across from the terminal, where major companies like Hertz, Enterprise, Budget, and Alamo are located. Additionally, the GoTriangle airport bus runs regularly between Raleigh and Durham, allowing for travel without a rental car.

Security checks and boarding procedures are relatively quick. The TSA PreCheck and CLEAR systems are in place, allowing pre-registered travelers to reduce wait times. Furthermore, the airport has well-equipped digital signage and a mobile app, making it easy to check real-time flight statuses and gate changes.

Raleigh–Durham International Airport plays a significant role not just as a transportation hub but also in the local economy. The business travel demand from companies located in the Research Triangle Park (RTP), international collaborations from university research institutions, and the tourism industry are all connected through this airport. For these reasons, RDU has established itself as a key hub in the Southeast, serving over 14 million passengers annually.

In summary, RDU offers the convenience and sophistication of an international airport without the crowds, and the friendliness of the staff reflects the warm hospitality typical of the South. Whether departing or returning, anyone traveling to or from Raleigh will experience the relaxed atmosphere of North Carolina right from this airport.
