How Do I Get to Baltimore-Washington International Airport?

Baltimore-Washington International Airport (BWI Marshall) sits 10 miles south of downtown Baltimore in Anne Arundel County, Maryland. The fastest route from central Baltimore is I-95 South to the BWI exit; drive time runs 20 to 30 minutes depending on traffic. Public transit options include the MARC Brunswick Line commuter rail, which connects Penn Station in downtown Baltimore directly to the airport in roughly 30 minutes for $8.50 to $9, and MTA bus routes 17 and 29, which take longer but cost $2 per ride.

Driving and Parking

If you drive, plan for parking costs: the hourly lot charges $5 for the first hour and $3 for each additional hour, capping at $20 per day. Daily parking (outdoor) costs $18, and the hourly structure makes sense for very short trips only. Economy parking, located off-site but connected by free shuttle, runs $12 per day and suits travelers willing to add 10 minutes to their airport arrival. Book directly through the BWI website rather than third-party parking sites to confirm current rates.

The airport sits at the intersection of I-95 and MD-170, making it accessible from both north (downtown Baltimore, I-83 from Pennsylvania) and south (Washington, D.C., via I-81 or I-66). GPS coordinates 39.1753, -76.6835 will direct you accurately; the main terminal entrance is well-marked from the highway.

MARC Rail from Downtown Baltimore

The MARC Brunswick Line is the most reliable choice if you're staying downtown. Trains depart Penn Station (1500 North Charles Street) approximately every 30 to 60 minutes during peak hours and less frequently midday and evening; check the current schedule on the MARC Commuter Rail website before your trip. The ride covers 30 miles in about 30 minutes and deposits you at the BWI Rail Station, which connects to the terminal via a short indoor walkway. Tickets cost $8.50 peak and $9 for off-peak travel; day passes are not available on this line.

Pay for MARC tickets at vending machines in Penn Station or use the MARC mobile app. Bicycles are permitted if you're combining cycling with rail transit. The rail station has baggage handling capacity for standard luggage, and you can store a suitcase temporarily if needed, though this incurs an additional fee. For current fees and procedures, contact MARC directly rather than relying on airport websites.

MTA Bus Service

Routes 17 and 29 serve the airport from various Baltimore neighborhoods. Route 17 (Eastside) originates at the Social Security Administration building in Woodlawn and runs through Canton; Route 29 (Westside) serves West Baltimore and the University of Maryland campus. Total travel time exceeds 45 minutes from most neighborhoods, and buses operate on 30 to 45-minute headways. This option suits travelers with minimal luggage and flexible schedules. The $2 fare covers your entire trip; use a ChartOne pass ($16 for a week of unlimited rides on local MTA buses) if you need airport access multiple times during a stay.

Rideshare and Taxi

Uber and Lyft operate from pickup zones on the departures level; fares from downtown Baltimore typically range $18 to $35 depending on surge pricing and traffic. Taxis queue at the ground transportation level and use a metered system; flat rates also apply on some routes. A taxi from downtown usually costs $40 to $50 before tip.

Which Route Makes Sense for Your Trip

Choose MARC if you're staying downtown or near Penn Station and traveling light; it's the cheapest reliable option. Drive if you're coming from outside central Baltimore, arriving with family or significant luggage, and can absorb parking costs. Use MTA bus only if you're comfortable with extended travel time and want to minimize expense. Rideshare offers middle ground pricing and door-to-door convenience, but surge pricing during peak travel windows (early morning, evening, bad weather) can match or exceed parking costs.

BWI Marshall itself has no toll road access, but drivers approaching from Washington, D.C. should note that I-66 inside the Beltway is toll-based during peak hours. Traveling via I-81 or other routes avoids this fee.
