You'd think a 400-mile hop between the capital of South Carolina and the nation's capital would be a total breeze. Just grab a ticket and go, right? Well, honestly, it's a bit more nuanced than that. If you're looking for Columbia to Washington DC flights, you aren't just picking a time; you're picking a side. Are you a Reagan National devotee or a Dulles loyalist? Do you want to pay $85 or $450?
The reality of flying out of Columbia Metropolitan (CAE) is that we’re a smaller hub. We’re cozy. You can get through security in ten minutes, but you’re also at the mercy of a handful of major carriers. For the DC route, that mostly means American Airlines and United.
The DCA vs. IAD showdown
Most people just search for "DC" and click whatever is cheapest. Big mistake.
If you land at Ronald Reagan Washington National Airport (DCA), you are basically in the city. You can see the monuments from the window as you land. You can hop on the Metro Blue or Yellow lines and be at the Smithsonian in 15 minutes. It’s the ultimate "I have a meeting at 10:00 AM" airport. American Airlines pretty much owns this direct route from Columbia, often running their CRJ-900s or Embraer 175s.
Then there’s Washington Dulles International (IAD).

Dulles is... far. It’s in Chantilly, Virginia. If you fly United, you’re likely landing here. While the Silver Line expansion finally connected Dulles to the Metro, you’re still looking at a 50-to-60-minute ride to get into the heart of the District. But here's the kicker: IAD is often significantly cheaper. I’ve seen one-way fares as low as $85 compared to $200+ for the convenience of Reagan National.
Is the drive actually better?
I get asked this constantly. "Should I just drive up I-95?"
Look, it’s 480 miles of road. On a perfect day with zero traffic—which literally doesn't exist on the I-95 corridor—it’s an eight-hour drive. Realistically? It’s nine or ten hours once you hit the bottleneck in Richmond or the chaos of Northern Virginia.
Flying takes about 90 minutes in the air. Even if you show up to CAE an hour early and spend an hour getting into DC from the airport, you’ve saved six hours of your life. Unless you're hauling a dorm room's worth of stuff or traveling with a family of five where the ticket costs multiply, flying wins every single time.

Timing your booking in 2026
Prices aren't what they used to be, but they aren't insane either.
- The Sweet Spot: January and February are historically the cheapest months. You can find round-trips for under $200 if you aren't picky.
- The Danger Zone: Mid-March through June. Why? Cherry blossoms and school field trips. Every 8th grader in the Southeast seems to be on a flight to DC in April.
- The Mid-Week Win: Tuesday and Wednesday departures remain the gold standard for saving fifty bucks.
I’ve noticed that American Airlines tends to run about 2–3 direct flights a day to DCA. If you miss those, you’re looking at a layover in Charlotte (CLT). Avoid the layover if you can. Charlotte is a great airport, but adding a connection to a 400-mile trip feels like a personal defeat.
What the airlines don't tell you about CAE
CAE is a breeze to navigate, but it’s small.
If your flight is at 6:00 AM (the common AA5603 flight), don't expect the full food court to be rocking at 4:30 AM. Grab your coffee, but maybe eat a real breakfast once you land in DC. Also, the parking at CAE is actually reasonable—about $8 to $12 a day—so don't feel like you have to Uber from Forest Acres if you're only gone for a weekend.

The "secret" third option: BWI
Sometimes, you'll see a deal for Baltimore/Washington International (BWI).
It sounds like it’s in a different state because, well, it is. But the MARC train or Amtrak can whisk you from BWI to Union Station in DC in about 35 minutes. If American or Southwest (via a connection) is running a massive sale into BWI, it's a viable backdoor into DC. Just don't do it if you're arriving after 9:00 PM; the train schedules get sparse, and an Uber from Baltimore to DC will eat every cent you saved on the airfare.
Final reality check
Flying from Columbia to Washington DC is about trade-offs.
If you have the budget, take the American Airlines direct to DCA. It’s the closest thing to a "private jet" experience in terms of efficiency. You walk out of the terminal and you're practically at the Pentagon. If you're on a budget, take the United flight to Dulles, bring a book for the Metro ride, and use the $100 you saved for a fancy dinner at The Wharf.
Actionable next steps for your trip:
- Check the airport code first: Ensure you aren't booking IAD when your hotel is in Alexandria (DCA is much closer).
- Monitor the 6:00 AM flight: It’s almost always the most reliable for on-time arrivals before the afternoon thunderstorms roll in.
- Download the DC Metro Map: Regardless of where you land, the Metro is your best friend.
- Book at least 21 days out: This specific route sees a sharp price hike for last-minute business travelers.
