Opened June 16, 1941, Ronald Reagan Washington National Airport serves the U.S. capital region from Arlington, Virginia. The airport operates under federal slot and perimeter rules and is primarily served by eight U.S. and Canadian carriers. American Airlines operates the largest schedule at DCA.
As the closest major airport to the U.S. Capitol, DCA underpins Congress’s weekly rhythm—enabling members and staff to shuttle to votes and return to home districts the same day. That convenience is why federal law also shapes the airport’s route map through slot controls and the 1,250‑mile Perimeter Rule.
Diplomatic delegations, cabinet officials, and advocates rely on the airport’s fast access to the federal core while specialized security programs balance proximity with protection of restricted airspace. The result is a uniquely “capital city” airport: close‑in, connected, and governed by policies few other U.S. airports share.
Planning in the late 1930s called for a modern, close‑in airport for the capital to replace Washington‑Hoover Airport (formed from Hoover Field and Washington Airport) along the Potomac near today’s Pentagon. Construction began in 1938 on reclaimed riverfront land, and the airport opened during the administration of President Franklin D. Roosevelt.
Eight airlines serve DCA with extensive U.S. domestic service plus Canada. Beyond‑perimeter slots added in late 2024 expanded long‑haul options.

Think compact and quick. DCA sits on the Potomac just south of downtown, so the metro ride is short and views are stellar on clear days. Peak crowds hit early mornings (business travelers) and late afternoons. Leave buffer time if you’re moving between Terminal 1 and 2—there’s no airside train.
Checkpoint waits vary by bank of gates. PreCheck and CLEAR are available in Terminal 2; Terminal 1 has a single checkpoint. Families and travelers with special assistance can call TSA Cares in advance for help at the checkpoint.
Terminal 2 has the widest selection—grab something near security if your gate area is light on options. In Terminal 1, aim for the central rotunda before you head to the end gates.
Arriving with a window seat can be a small thrill here—on clear days, approaches trace the Potomac with postcard views of the monuments. Inside, wayfinding is straightforward: Terminal 1 is compact; Terminal 2 is modern and walkable between concourses after security. If you’re short on time, grab food near your checkpoint before heading to distant gates.
Inside Terminal 2, concourses are walkable after security—follow the overhead signs for B, C, D and E. To move between Terminal 1 and Terminal 2, use the free landside shuttle buses outside arrivals; stops are clearly marked and run frequently. If you’re tight on time, check your airline app for the nearest checkpoint and food options before you trek to a distant gate.
