BWI Airport Transportation Guide: Every Way to Get There and Back

Baltimore/Washington International Thurgood Marshall Airport sits in Anne Arundel County near Linthicum, between Baltimore and Washington, close to I-95, I-195, I-97 and the Baltimore-Washington Parkway. That location gives it more ground transportation choices than most airports its size: two kinds of rail, local and regional buses, taxis, rideshare, several tiers of parking, a rental car facility and chauffeured car service.

This guide walks through each option in plain terms, with how it works and who it suits. Schedules, routes and rates change, so confirm the details with the operator before you travel. We do not quote transit fares or parking rates here for that reason.

MARC and Amtrak at BWI Rail Station

BWI Rail Station is on the Northeast Corridor, roughly a mile from the terminal. It is served by MARC's Penn Line, which runs between Washington Union Station and Baltimore Penn Station and continues north toward Perryville, and by Amtrak trains on the corridor. A free shuttle bus connects the rail station with the terminal, stopping on the lower level.

The train is a strong option if you are starting near Union Station, Baltimore Penn Station or another Penn Line stop such as New Carrollton, Bowie State or Odenton, and you are traveling light. It is also useful for visitors arriving at BWI and continuing to Philadelphia, Wilmington or New York on Amtrak.

The trade-offs are the shuttle transfer, the schedule and the first and last mile. Allow extra time for the shuttle, check service for very early and late flights and on weekends, and think about how you will get between your home and the station with bags.

Baltimore Light RailLink at the Terminal

The Maryland Transit Administration's Light RailLink has a station at the terminal itself, at the lower level near the international end of the building. The line runs north through Linthicum and into downtown Baltimore, with stops near the Convention Center, Camden Yards and the Lexington Market area, and continues to Hunt Valley in Baltimore County.

For travelers headed to a downtown Baltimore hotel, a convention or a ballgame, it is an economical way in. It makes many stops, so it is slower than a direct car, and it does not run around the clock. It does not serve Washington, Annapolis or Columbia.

Local and Regional Buses

Public buses stop at the terminal, including MTA local bus service toward Baltimore and surrounding Anne Arundel County communities. Regional and county systems in central Maryland have also connected the airport area with nearby employment centers. Routes and numbering have changed several times in recent years, so look at current MTA and regional transit maps rather than relying on an old itinerary.

Buses are the lowest-cost way to reach the airport and work best for airport employees, travelers with one small bag and people with flexible schedules. With checked luggage, children or a tight connection, the extra travel time and transfers are a real cost.

Taxis and Rideshare

Taxis are available at a staffed stand on the lower level outside baggage claim. Fares are metered, so the total depends on distance and traffic. Taxis are convenient on arrival because there is nothing to arrange, which makes them a reasonable choice for short, unplanned trips to nearby hotels and offices.

Uber and Lyft both operate at BWI. Drop-offs happen at the departures curb, and arriving passengers meet their drivers at designated rideshare pickup areas, so follow the signs and the app's instructions. Pricing is dynamic and changes with demand. Rideshare is a good fit for solo travelers at ordinary hours from well-served areas. For pre-dawn pickups in the suburbs, holiday weeks and larger parties, availability and vehicle size are less predictable. Our separate articles compare the two models in detail.

Driving Yourself: Parking at BWI

The airport operates several parking products at different price points. In general terms:

Hourly garage: directly across from the terminal, intended for short stays and for meeting or dropping off passengers
Daily garage: covered parking a short shuttle ride from the terminal, a common choice for trips of a few days
Express parking: a premium surface lot where a shuttle picks you up at your car
Long-term lots: the most economical airport-run option, served by shuttle buses, best for longer trips
Cell phone lot: a free waiting area for drivers picking up arriving passengers

What to Weigh Before You Park

Private off-airport lots along the nearby hotel corridor offer another alternative with their own shuttles. Whichever you choose, add time for finding a space and riding the shuttle, and remember that lots can fill during peak holiday periods. For a long trip, compare the total parking bill for the whole stay against a round-trip car service. For many households the numbers are closer than expected, and the car service saves the drive home after a late arrival.

Rental Cars

BWI's rental car companies operate from a consolidated rental car facility away from the terminal. Free shuttle buses run between the lower level of the terminal and the facility. Build the shuttle ride and the counter or kiosk time into your schedule in both directions, especially when returning a car before an early flight.

A rental makes sense when you need a vehicle throughout your stay, for example a week visiting family across several counties. If you only need to get from the airport to one address and back, other options are usually simpler.

Chauffeured Car Service

A pre-booked chauffeur is the door-to-door option. You reserve a vehicle class, share your flight number and address, and the rest is handled. With 92 Limo Service, every airport pickup is tracked in real time, curbside pickup is included, and meet and greet inside baggage claim is available for an additional charge. Airport pickups include 45 minutes of complimentary wait time on domestic arrivals and 60 minutes on international arrivals, timed from touchdown.

The quote is confirmed before you ride, with gratuity, tolls, parking and other applicable charges disclosed before confirmation.

Frequently Asked Questions

Is there a train to BWI Airport?

Yes. MARC Penn Line and Amtrak trains stop at BWI Rail Station, and a free shuttle bus connects the station with the terminal. Baltimore's Light RailLink also has a station at the terminal itself with service to downtown Baltimore and Hunt Valley.

What is the cheapest way to get to BWI?

Public transit, meaning MTA buses, Light RailLink or the MARC Penn Line, is generally the least expensive. The trade-off is time, transfers and limited service at very early and late hours. Check current schedules with the operator.

Where do I find taxis and rideshare at BWI?

Taxis load at a staffed stand on the lower level outside baggage claim. Rideshare drivers meet arriving passengers at designated pickup areas. Follow terminal signs and the instructions in your app.

Is parking at BWI or a car service a better deal?

It depends on the length of your trip and how many people are traveling. For short trips, parking is often economical. For longer trips, compare the full parking total against a round-trip quote, and factor in the shuttle time and the drive home after a late arrival.

Yes. Dispatch and reservations run 24/7, every airport pickup is tracked in real time, and airport pickups include 45 minutes of complimentary wait on domestic arrivals and 60 minutes on international arrivals, timed from touchdown.
