Essential Travel Information for BWI Marshall Airport

Layout & Navigating BWI:

• The terminal is linear. All security checkpoints lead to the same post-security corridor with moving walkways connecting all concourses.
• Southwest Airlines operates from Concourses A, B, and E. Check your boarding pass for your specific gate.
• International arrivals clear U.S. Customs and Border Protection (CBP) in Concourse D. After clearing customs, you exit into the public baggage claim area in the main terminal.

Ground Transport Strategy:

• To/From Washington D.C.: The MARC Penn Line train is the best value and is often faster than driving during rush hour. Amtrak is faster but more expensive. Ride-hailing is convenient but costly and subject to I-95/295/Balt-Wash Parkway traffic.
• To/From Downtown Baltimore: The Light Rail is very cost-effective. MARC is faster to Penn Station. Ride-hailing takes 20-40 minutes.
• Between the Terminal and Rail Stations: Remember the free shuttle bus to the BWI Rail Station (for MARC/Amtrak). The Light Rail station is a short, covered walk from the terminal.

Parking at BWI:

• Hourly Garage: Connected directly to the terminal, most convenient, most expensive.
• Daily Garage: Slightly further walk, covered.
• Long-Term / Economy Lots: Most affordable. Served by frequent shuttle buses to the terminal.
• Reserved Parking: Can be booked online in advance for a discount in the Daily Garage.

Bottom Line: BWI Marshall Airport is a user-friendly, efficient alternative to the Washington D.C. airports. Its strength lies in its excellent ground transportation, especially the rail connections. For a smooth experience, use the MARC or Light Rail for city access, allow extra time for international arrivals processing, and check your concourse carefully if flying Southwest due to their large presence across multiple concourses.
