BWI to DC , Thurgood Marshall Airport sits about 30–35 miles from downtown Washington, DC, and getting between them takes anywhere from around 25 minutes (Amtrak Acela ride time) to well over an hour (any option in real traffic). Here's every genuine option, honestly compared by cost and time — including one important correction a lot of other guides on this topic still get wrong.
- Distance: ~30–35 miles, roughly a 45–75 minute drive depending on traffic.
- No direct Metro: The old B30 bus to Greenbelt was discontinued in 2020 — don't plan around it.
- Cheapest: MARC Penn Line (~$8–$9), but weekend service thins out sharply.
- Fastest ride: Amtrak Acela (~25–30 min) — though every train needs a shuttle transfer.
- Trains end at Union Station, not your final destination — factor the onward transfer in.

How Far Is BWI From DC?
BWI is roughly 30–35 miles from downtown Washington, DC, depending on your specific start and end points. For context, that's noticeably farther than Reagan National (DCA), which sits right on the city's edge, but much closer to Baltimore — BWI is only about 9 miles from downtown Baltimore, which is part of why train service between BWI and DC runs through Baltimore's own commuter corridor rather than being a dedicated airport link.
BWI to DC: Every Option Compared
The honest side-by-side. Train times are ride time only — add shuttle and transfer time on both ends.
| Option | Cost | Time | Best For |
|---|---|---|---|
| MARC Train (Penn Line) | ~$8–$9 one-way | ~30–35 min ride + shuttle | Budget, light luggage, weekdays |
| Amtrak (Regional/Acela) | $15–$65+ one-way | ~25–30 min ride + shuttle | Faster trip, weekends, pay more |
| Rideshare (Uber/Lyft) | ~$50–$80 | ~45–75 min w/ traffic | Solo/couple, door-to-door |
| Taxi | ~$80–$90 | ~45–75 min w/ traffic | No app, taxi-stand option |
| Driving yourself | Parking + gas | ~45–75 min w/ traffic | If you have a car at BWI |
| Private car service | Fixed quote | ~45–75 min w/ traffic | Groups, luggage, no surge |
Train From BWI to DC: MARC vs. Amtrak
Both trains use the same station — BWI Rail Station, connected to the airport terminals by a free shuttle that runs every 10–15 minutes, 24 hours a day. Neither station is inside the terminal, so factor in shuttle time on both ends of the trip.
MARC Penn Line is the budget option: around $8–$9 one-way, roughly 30–35 minutes of ride time between Union Station and BWI. The catch is frequency — it's a commuter train, so weekday service is frequent, but weekend service drops off sharply (as few as six total departures on a Sunday). If you're traveling on a weekend, check the exact schedule and current fare on the official MTA Maryland fares page before counting on it — and note there's a surcharge if you buy from a station machine or agent rather than the app.
Amtrak costs more — commonly $15 to $65 or higher depending on class and how far ahead you book — but runs a fuller schedule including weekends, and Acela shaves the ride to roughly 25–30 minutes. Booking a few days ahead typically beats a same-day fare by a meaningful margin.
Either train gets you to Union Station, not directly to "downtown DC." From there you're transferring to Metro's Red Line or another mode to reach your final destination — time that most cost/time comparisons for this route don't fully account for.
BWI to DC by Rideshare or Taxi
Uber and Lyft pick up at the terminal curb (typically the Departures/Ticketing Level), with totals commonly in the $50–$80 range depending on demand and exact destination — and surge pricing is a real factor at peak travel times. Taxis are available at a dedicated stand and commonly run a bit higher, in the $80–$90 range to downtown.
Both are genuinely faster door-to-door than the train-plus-shuttle-plus-Metro chain if your destination isn't near Union Station, since you skip the transfers entirely. The tradeoff is cost and the possibility of surge pricing at exactly the times you're most likely to travel — peak arrival banks, holidays. It's the same reason many travelers arrange airport transportation ahead of time instead of leaving the ground leg to chance.
Best Way to Get From BWI to DC: It Depends on Your Trip
| Solo, light luggage, budget, weekday | MARC — hard to beat at ~$8–$9. |
| Weekend, or want a faster ride | Amtrak — fuller schedule, quicker on Acela. |
| Destination not near Union Station | Rideshare or taxi — door-to-door, no transfer. |
| Group, luggage, or want a locked price | Private car service — fixed quote, no surge, curbside. Phone: (410) 451-0000 |
For a group or anyone with significant luggage, a private car service into DC quotes a fixed price upfront and picks you up curbside — without the shuttle-then-train-then-Metro chain the train options require.
Why Groups and Luggage Change the Math
The train options look cheapest per person, but that math shifts fast once you're not traveling solo. A group of four paying $8–$15 each for MARC or Amtrak is still dealing with a free shuttle transfer, then a train, then likely another transfer at Union Station to reach a final destination — with luggage in tow through every step. At that point, a private car service quoting one fixed price for the group, as a single door-to-door trip with no transfers, often works out comparable in total cost while being dramatically less hassle. And unlike rideshare, the price is locked in before you land, with no surge risk if your flight arrives during a busy window.
