Founding The region's first airport opened in 1929 as
Raleigh Municipal Airport, south of Raleigh. It was quickly outgrown, and in 1939 the
North Carolina General Assembly chartered the Raleigh–Durham Aeronautical Authority to build and operate a larger airport between Raleigh and Durham. This was promoted by
Eastern Air Lines, led by then chairman
Eddie Rickenbacker, who wanted to make RDU a stop on the airline's New York–Miami route. The new Raleigh–Durham Airport opened on May 1, 1943, with flights by Eastern Airlines. The passenger terminal was built from materials remaining after the construction of four barracks for the Army Air Forces Air Technical Service Command airfield. The three runways the airport had in 1951 are still visible on the southeast side of the airport: 4500-ft runway 5, 4500-ft runway 18 and 4490-ft runway 14. After
World War II,
Capital Airlines joined Eastern at RDU;
Piedmont Airlines arrived in 1948. The original Terminal 1 building was constructed in 1955, that previously served as a temporary structure for barracks for the prior
United States Army air field. The April 1957 Official Airline Guide shows 36 departures a day: twenty Eastern, eight Capital and eight Piedmont. Nonstop flights did not reach beyond
Washington,
Atlanta, or the
Appalachians (but Eastern started a
Super Constellation nonstop to
Newark in 1958). The next airline (aside from United's takeover of Capital in 1961) was
Delta Air Lines in 1970. In April 1969, nonstops didn't reach beyond New York or Atlanta, and
Chicago was the only nonstop west of the Appalachians. RDU's first scheduled jets were Eastern
727s in 1965. Like many airports in the southern United States, it was operated as segregated facility with separate waiting areas for "White" and "Colored" people. It was later desegregated in the 1960s in response to protests by students at local universities. In the 1970s, the last decade before airline deregulation, Piedmont connected RDU to the North Carolina cities of Asheville, Charlotte, Greensboro, New Bern, Rocky Mount, Winston-Salem, and Wilmington. It also connected to Norfolk, Virginia; Richmond, Virginia; and Washington, among others. United flew to Asheville, Charlotte, Huntsville, and Newark, while Eastern flew to Atlanta, Charlotte, Miami, New York, Philadelphia, Richmond, and Washington, and Delta flew to Chicago and Greensboro. After deregulation,
Allegheny Airlines arrived in 1979, and by 1985
Trans World Airlines,
American Airlines,
Ozark Air Lines,
People Express,
New York Air and
Pan Am had all put in appearances. Terminal 1, previously known as Terminal A, was first opened in 1982. Runway 5L/23R was completed in 1986. The December 1987 timetable shows AA nonstops to 36 airports and American Eagle prop nonstops to 18 more. In 1988, the first international destination was
Paris-Orly with AA. Caribbean destinations started in 1989, with routes to
Bermuda,
Cancún,
St. Croix and
St. Thomas. AA's December 1992 timetable, around the time of the hub's peak, showed 211 daily departures to 64 destinations, almost all in the eastern United States (the westernmost destinations being AA's hubs at
Dallas/Fort Worth and
Chicago–O'Hare). The hub faced intense competition from
Delta and
Eastern in
Atlanta,
Northwest in
Memphis, and from
USAir in
Charlotte, as well as the short-lived
Continental hub in
Greensboro that opened in 1993. AA operations were reduced until June 1995 when they closed the hub. In 1996,
Air Canada became the airport's first international carrier with service to
Toronto.
Canadian Regional Airlines also started service to Toronto in 1997. In 1995, Midway had flights to
Boston,
Hartford,
Long Island, Newark, in the Northeast; and to
Fort Lauderdale,
Jacksonville,
Orlando,
Tampa and
West Palm Beach in Florida. They also served Cancún. AA subleased its gates at RDU to Midway in order to repay $113 million in AA-guaranteed bonds that had been used to construct the hub facilities. Midway suspended service for some time after the
September 11, 2001 attacks, and ceased operations in 2002, filing for bankruptcy in 2003. The
United Service Organizations opened a lounge in 2004. The airport was briefly considered for a
FedEx hub in 2006 before eventually opening at
Piedmont Triad International Airport in
Greensboro, North Carolina.
Recent history RDU's post-hub years have brought the addition of new carriers and destinations, notably discount carriers such as
Allegiant Air,
Southwest Airlines and
Frontier Airlines. Because of the economic downturn and high fuel prices in 2008,
American ended most
point to point flights it operated out of the airport. Several mainline flights were also dropped and service to other cities was reduced or downgraded. Other airlines also cut flights and destinations including
United Airlines and
US Airways. AA moved to
London-Heathrow from Gatwick in 2008. AA
Admirals Club moved to Terminal 2 in 2008, with the rest of AA moving operations to that terminal.
Delta Sky Club opened in 2009, and expanded in 2016. By 2010, RDU's traffic began to recover. In the first few months of the year, passenger numbers stabilized at RDU, ending the decrease the airport experienced in 2008 and 2009. In the first four months of 2010, 2.7 million passengers traveled through RDU. Growth was flat compared to the same period a year before, but these signs were positive indicating that the decline was over. Airlines at RDU began to add new services to the schedule with both legacy and low-cost carriers significantly increasing service since the early 2010s. Terminal 1 was renovated in 2014. The airport restarted Paris service, this time to
Paris–Charles de Gaulle in 2016 with Delta. Delta also maintains a satellite
flight attendants base. The
United Club opened in 2019, which is the airports third passenger lounge. Also that year,
Air Canada Express started service to
Montréal–Trudeau. All international flights were cancelled in 2020, due to
COVID-19. Both AA to Heathrow and Delta to Paris restarted in 2022. Also in 2022,
Icelandair started service to
Reykjavík–Keflavík. In November 2022,
Avelo Airlines announced the opening of an operating base at the airport, with service started on February 15, 2023. The airline closed the base on January 28, 2026.
Air France took over Paris service from Delta in 2023. The base also supports over 140 aircraft. Additionally, RDU started its fifth European flight with nonstop flights to
Dublin in the spring 2026 via
Aer Lingus. The existing runway 5L/23R will become a taxiway for the new runway. After modifying the planned runway length multiple times, the
Federal Aviation Administration authorized the construction of the new runway on September 5, 2023. The construction of RDU's new 5L/23R runway began on October 11, 2023. The new runway will be built at a length of , and is anticipated to start paving in 2027, to be finished in 2029. In June 2023, the Airport Authority Board approved an agreement to advance the planning process for Terminal 1 expansion to allow for future growth as RDU reached new passenger traffic records and destinations served. RDU is also planning on expanding their customs and border protection center to accommodate the increase in international flights at RDU. ==Facilities==
