Baltimore-Washington International Thurgood Marshall Airport (IATA: BWI, ICAO: KBWI) serves the Baltimore-Washington
Metropolitan Area in the United States. It is commonly referred to as BWI or BWI Airport, after its IATA Airport
Code. The airport is located in Anne Arundel County, Maryland and is about 10 miles (16 km) south of Baltimore and 30 miles (48 km)
northeast of Washington, D.C.
A record 21.9 million passengers traveled through BWI in 2010, making it the United States' 24th
BWI Rail Station opened in 1980, providing a rail connection to passengers on the busy Northeast Corridor. BWI
became first airport in the U.S. to be served by a dedicated intercity rail station. In particular, the station
provided relatively easy transit access to Washington, D.C., something Dulles International Airport lacks.
In the late 1990s, a new international terminal (Concourse E) was added, though Dulles continues to hold the
lion's share of the region's international flights. British Airways and Icelandair have had a presence at BWI for many
On July 12, 2013, BWI Airport and the Maryland Aviation Administration launched a 3-year $125 million construction project. This project will include
modernizing concourse D, a new airside connection linking concourse D and E, and the new configuration of the concourses will allow 2 gates on concourse D
to serve both domestic and international flights. The project is scheduled to begin in late 2014 with an estimated completion date of fall 2016.
