Baltimore/Washington International Thurgood Marshall Airport (BWI) sits in Anne Arundel County, Maryland, between Baltimore and Washington. It has one terminal with five concourses: Southwest uses A, B and C, most other domestic airlines use D, and international flights use E.
International passengers clear US passport control and customs in Concourse E and collect their bags there before exiting to the lower level. Domestic passengers follow the signs from their concourse to Baggage Claim on the Arrivals/Lower Level, where taxis, shuttles and pre-booked drivers wait.
Maryland is on Eastern Time and changes its clocks for daylight saving time.
Entry requirements and local notes
Entry to the US. You need a valid passport and either a US visa or an approved ESTA under the Visa Waiver Program, obtained before you board. Global Entry and Mobile Passport Control can shorten the line in Concourse E.
Customs. Declare food, plants and animal products, and cash over $10,000.
Pickup curbs. Taxis wait on the lower level and app-based rides pick up on the upper level, so go to the meeting point named in your confirmation and ignore offers of rides inside the terminal.
BWI, Dulles or Reagan. Washington has three airports. If your ticket says IAD, you are landing at Dulles in Virginia; see our Dulles airport transportation page.
