You're standing in line at a coffee shop in Crystal City, looking at your boarding pass, and there it is: DCA. If you're looking for the airport code for Reagan National, that’s the one. Simple, right? But if you stop and think about it for more than two seconds, it doesn't actually make any sense. There isn't an "R" for Reagan. There isn't an "N" for National. Honestly, if you didn't know better, you’d think you were flying into some random city starting with D.
Most people just shrug it off. They figure it’s just one of those weird government things. Washington, D.C. is full of them. But the story behind those three letters is actually a trip through aviation history, local politics, and a massive name change that people are still arguing about today.
Why DCA Doesn’t Match the Name
Let’s get the basics out of the way. DCA stands for District of Columbia Airport.
It’s a relic. A fossil from 1941. Back when Franklin D. Roosevelt was overseeing the construction of the terminal on a patch of mud called Gravelly Point, the airport was just "Washington National Airport." The "DCA" code was assigned because it was the primary—and at the time, only—major commercial field serving the District.
Then 1998 happened.
President Bill Clinton signed legislation to rename the facility Ronald Reagan Washington National Airport. It was a move that sparked a fair amount of local friction. If you talk to a lifelong D.C. resident today, they might still stubbornly call it "National." If you talk to a pilot or a frequent flyer, they just call it DCA. The IATA (International Air Transport Association) almost never changes codes once they are baked into the global reservation systems. It’s too expensive. It’s too confusing. So, while the sign on the building changed, the airport code for Reagan National stayed frozen in time.
The Geography is Kinda Wild
If you’ve ever flown into DCA, you know the "River Visual" approach. It is, hands down, one of the most nerve-wracking and beautiful landings in the United States.
Because of the highly restricted airspace over the White House, the Pentagon, and the Capitol, planes can't just fly a straight line. Instead, pilots have to follow the curves of the Potomac River. You’re banking hard, looking out the window at the Lincoln Memorial, and then—thud—you’re on the tarmac.
Technically, the airport is in Arlington, Virginia. But here’s the kicker: the land it sits on is actually part of the District of Columbia. How? Well, the original boundary of D.C. was a ten-mile square that included the Potomac River up to the high-water mark on the Virginia side. When the airport was built on filled land, that land technically remained under D.C. jurisdiction, even though you have to drive through Virginia to get to the front door. This weird jurisdictional quirk is why the airport code for Reagan National uses the "DC" prefix rather than something reflecting its Virginia zip code.

Comparing the D.C. Area Codes
You have three choices when flying into the DMV (D.C., Maryland, Virginia) area. They aren't created equal.
- DCA (Reagan National): The "inner circle" airport. It’s literally minutes from downtown. You can take the Blue or Yellow Line on the Metro and be at the Smithsonian in 15 minutes. It has a "perimeter rule," meaning most flights have to be shorter than 1,250 miles, though Congress keeps adding exceptions.
- IAD (Dulles International): Located out in Loudoun County, Virginia. It’s huge. It’s where you go for international flights or long-haul domestic trips. It’s famous for the Eero Saarinen-designed terminal that looks like a concrete hammock.
- BWI (Baltimore/Washington International Thurgood Marshall): It’s up near Baltimore. Often the cheapest option, especially if you’re flying Southwest, but it’s a hike if you’re staying in Virginia.
The Name Debate That Never Ends
It’s been over 25 years since the name change, and yet the "Reagan vs. National" thing is a great way to tell how long someone has lived in the area.
When the change was proposed, it wasn't exactly a unanimous "yes." Local leaders in D.C. and Virginia weren't thrilled about the federal government imposing a name on an airport they felt belonged to the community. To this day, the Metro station is officially "Ronald Reagan Washington National Airport," but most locals just refer to the airport code for Reagan National as the name itself. "I'm heading to DCA" is the neutral ground. It avoids the politics. It’s just functional.
What You Need to Know Before You Go
If you are booking a flight, don't look for "RWA" or "WNA." They don't exist. You are looking for DCA.
One thing that catches people off guard is the size. Compared to Dulles, Reagan is compact. Terminal 2 is where the bulk of the action is—that’s the beautiful one with the yellow exposed beams and the views of the airfield. Terminal 1 is the "old" part. It’s circular, a bit cramped, and mainly serves airlines like Southwest and Frontier.
Pro Tip: If you have time, head to the North end of Terminal 2. The windows give you a perfect view of the monuments across the river. It’s one of the few airports where the "airport view" is actually world-class.

Navigating the Perimeter Rule
The airport code for Reagan National comes with baggage—specifically, federal law. Because the airport is small and close to the city, the government limits how many long-distance flights can land there. They want to push that traffic to Dulles.
This means if you’re flying from Los Angeles, San Francisco, or Seattle, your options into DCA are very limited. You usually have to snag one of the few "beyond-perimeter" slots or connect through a hub like Chicago or Dallas. If you’re flying from the East Coast or the Midwest, you’re golden.
Ground Transportation Hacks
Honestly, do not take an Uber if the Metro is running.
The DCA Metro station is connected via covered walkways to Terminals 2 and 1. It’s incredibly efficient. If you do take a ride-share, be prepared for the "cell phone lot" dance. The traffic loops at Reagan can get backed up fast, especially during the 5:00 PM rush when lobbyists and tourists are all trying to flee the city at the same time.
Final Logistics to Keep in Mind
- Security: Clear and TSA PreCheck are available in Terminal 2. The lines move relatively fast compared to other major hubs, but Monday mornings are brutal with "super commuters" heading to the Hill.
- Food: Most of the good stuff is post-security. Look for local favorites like Ben's Chili Bowl (a D.C. institution) if you want a "half-smoke" before you board.
- The Code: Just remember DCA.
When you see those three letters on your luggage tag, you aren't just looking at a location. You're looking at a piece of 1940s history that survived a renaming, a massive expansion, and the ever-changing landscape of American politics. It’s the gateway to the capital.
Actionable Steps for Your Next Trip
- Double-check your tickets: Always confirm the code is DCA and not IAD. People make the "Dulles vs. Reagan" mistake every single day, and they are 30 miles apart.
- Check the Metro schedule: If your flight lands after midnight, the Metro might be closed. Have a backup plan.
- Pick the right side of the plane: If you are flying in from the north, sit on the left side of the plane for the best views of the National Mall. If you're departing to the north, sit on the right side.
- Use the DCA app: The airport's official site provides real-time parking availability, which is crucial because the garages fill up by Tuesday morning during peak business weeks.
