Train from BWI to DC

Though BWI is not as convenient as DCA/National Airport (Reagan), there are still many easy ways to travel from BWI into the city. 

Taking the train from BWI to downtown DC is probably the most popular public transportation option.

Both regional (Amtrak) trains and suburban commuter (MARC) trains connect BWI to Union Station, DC.

From the BWI train station, the airport offers free and frequent shuttles to get to the terminal. The shuttles run 24/7 at 6-minute intervals (except 1am-5am when it is 25 minutes)

MARC is an easy and efficient way to travel between Baltimore and DC. Many use the Penn Line for transport to and from BWI airport.

  • Trains depart from Union Station and make 4 additional stops before arriving at BWI.
  • The total length of the journey from DC to BWI is approximately 35 minutes, thus making the MARC a very quick and efficient way to travel between BWI and Washington, DC.
  • There is service on both the weekdays and weekends.
    • Weekday trains run very frequently as so many commuters utilize the Penn Line. The first train departs from BWI at 4:40 am and the first from Union Station departs at 5:50. Trains continue to run every 20 minutes during rush hour and then every hour during the rest of the day until 9:30 and 10:30 pm, when the last trains depart from BWI and Union Station, respectively.
    • Saturday trains run between 9am-10pm and depart every hour during rush hour and every few hours throughout midday. On Sundays, trains run even more infrequently, with only 6 departures from either BWI or Union Station throughout the day. 

One way fares cost just $8 each way (as of January 2023) and can be purchased from Amtrak Quik-Trak ticket vending machines or the ticket office.

Passengers may also purchase tickets on the train with cash from the conductor, however, there is a $5 surcharge added to the price of the ticket. 

Pros: Quick, efficient, and affordable. The MARC is extremely reliable and very cheap as long as tickets are purchased at the station before boarding the train. 

Cons: Weekend trains run somewhat irregularly, especially on Sundays. Sometimes passengers will have to wait several hours before the next train departs. Also, there is no late night service. 

Amtrak Train

Amtrak also has a train that runs from the BWI Marshall Rail Station to Union Station in DC. Free shuttle service is provided between the airport and the BWI Rail Station.

The cost of the train ticket into Union Station varies depending on the time of your travel, but expect to pay between $15-$45 for a one-way ticket.

Tickets purchased at the last minute or during rush hour are typically much more expensive. 

Amtrak BWI

Passengers can also choose between 3 different types of tickets: Saver, Value, and Flexible.

  • Saver, the cheapest option, is non-refundable and does not recognize discounts for students, senior citizens, or AAA members.
  • Value tickets allow refunds in certain situations and do recognize all discount programs.
  • Flexible is 100% refundable and also recognize discount programs.

The length of the journey on Amtrak is between 21-27 minutes, making this the fastest way for guests to travel between BWI and Union Station.

Trains depart every 10-60 minutes, depending on the time of day. The first trains depart at 3 am, while the last depart at 10 pm. 

Some Amtrak trains do not allow passengers to bring any checked bags, so be sure to check baggage allowance according to your needs. 

Visit the Amtrak website to book tickets in advance! 

Pros: Very fast and efficient service. Amtrak is the quickest transportation service between BWI and Washington, DC. 

Cons: Though it is possible to find reasonably priced Amtrak tickets, this is often one of the more expensive ways to travel. 

Washington DC Travel Tips

Airport Shuttles

GO Airport Shuttle

This company offers 24/7 airport pick up and drop off with private cars and shared vans – you can even get a limousine!

With upfront pricing, you’ll know how much your trip will be when you book. You can also request a car seat or a kennel.

Pros: Door to door service. Good choice for those with luggage or want direct service for a lower cost. Offers car seat or kennel if traveling with children and pets. You can also choose to tip in advance when reserving.

Cons: Can take a lot of time depending on traffic and how many others in the van get dropped off before you.

Transportation between BWI Airport and Washington, D.C.


If traveling with a group or large family, the SuperShuttle may be the easiest and most affordable option. Guests can choose between a shared-ride van as the cheapest option or a non-stop van which is slightly more expensive.

*As of January 2023, due to Covid-19, the shared-ride service has limited offerings.

Also on offer are ExecuCars, which is an SUV meet-and-greet service that operates as a luxury door-to-door transportation option.

Rates vary immensely depending on your destination and type of SuperShuttle service.

Those traveling as a family or group receive a discounted rate as compared to those traveling on their own. For example, a single ticket for the shared-ride SuperShuttle is $37 per person, whereas the non-stop SuperShuttle is $125.

Additionally, those interested in traveling via SUV ExcuCar will pay $113. A family or group of 5, on the other hand, can travel by shared-ride SuperShuttle for a total of $85, by non-stop SuperShuttle for $125 in total, or the SUV ExcuCar for $113 in total. For a complete list of their prices, please see their website for more details.

Though the ease of a door-to-door shuttle service is appealing, always consider the time at which you will be traveling as trips taken during rush hour can take well over an hour.

SuperShuttle shared van rides are not currently available to book but other shuttle services are listed on their website (as of January 2022). 

Pros: Easy travel option that is ideal for larger families or those with young children who do not wish to use public transportation. 

Cons: A very expensive alternative for those traveling on their own or as a couple. The shared-ride SuperShuttle can take a very long time, especially when traveling during rush hour. 

B30 Bus

The B30 Metrobus is a public bus service running from BWI to the Greenbelt Metro Station on weekdays.

During weekdays, this bus runs every 60-70 minutes and it's available from 6:54 am - 10:44 pm. While it used to run on weekends, that service is not currently available.

The B30 Metrobus is $6 per person or $3 for seniors and people with disabilities. Fares can be paid either with cash or a SmarTrip card.

NOTE: This bus service has been cut back significantly in recent years, and it's possible it will eventually be cut.

Pros: This is undoubtedly one of the cheapest options for locals who live in the area. At just $6 for a ticket, you could save a lot of money using the B30 bus.

Cons: Since the B30 only runs once an hour, it's not the most reliable or convenient way to get from BWI to Washington DC. They're also talking about canceling this service, so there's a strong chance it won't even exist in the next few years.

BWI to DC Airport Taxi / Uber / Lyft

It is also possible to hire a taxi from the airport straight into the DC. Taxis are available 24/7 and are located just outside baggage claim.

The estimated cost for a trip to downtown DC is $90, though rates do vary.

Uber/Lyft taken without any added surcharge fees usually cost between $41-$55, though the price can increase during rush hour.

Though personal taxis might seem like one of the quickest ways to travel between Washington, DC, and BWI, the length of the journey very much depends on the time of day.

Taxis that operate during rush hour can take significantly longer than other transportation services. 

Pros: Door-to-door transportation. Extremely easy, especially for families. 24/7 availability. 

Cons: Expensive for single travelers and can take more than an hour if traveling during peak times. 


If you are looking for peace of mind that you will be picked up from the airport on time, and taken to your destination in a timely manner, DCAcar car service is an excellent choice.

You can make the reservation ahead of time, and give the company your flight information so they know whether you’ll be early or late.

At BWI your driver will meet you at baggage claim, and help you with your luggage. You can get a rate estimation and make a booking with this highly rated car service company here.

Pros: Luxury personalized service

Cons: Costly - but DCByFoot guests get a 5% discount by using the promo code: dcbyfoot.

Rental Car Service

Finally, visitors can also opt to travel between BWI and DC via a rental car service. If you only require a car for transportation to and from the airport, then you should certainly look into other options.

However, for those already planning to rent a car during their visit to DC, this is an easy way to get to the airport. 

Of course, prices vary immensely depending on the length of rental, the company, and the quality of the vehicle. Also, guests should factor in the cost of fuel, which can dramatically increase the cost of renting a car. 

As is the case with guests using taxis or the SuperShuttle, those who opt for renting a car should always consider the time at which they will be traveling between BWI and DC as traffic can get very congested during rush hour.

Pros: Freedom to travel at any time and directly to/from your destination. 

Cons: This is the most expensive option and only one that visitors should consider if they want a rental car for other purposes.
