Editorial Aerodrome Deep Dive: Baltimore/Washington International Thurgood Marshall Airport (BWI)

Curated Aerodrome Profile

Baltimore/Washington International Thurgood Marshall Airport is the primary domestic traffic workhorse of the Chesapeake region. Its 10,502 ft runway 10/28 easily accommodates widebody charter and scheduled international flights, while intersecting runway 15R/33L provides crosswind coverage against Atlantic cold fronts. Located at 146 ft elevation, BWI offers superior turn-around efficiency and slot availability compared to slot-controlled DCA.

Runway Layout & Magnetic Alignments
Three active runways: primary Runway 10/28 (10,502 ft), secondary Runway 15R/33L (9,500 ft), and general aviation Runway 15L/33R (5,000 ft).
Expansion Milestones & Predecessor Facilities
Opened in 1950 as Friendship International Airport, renamed Baltimore/Washington International Thurgood Marshall in 2005. Transformed by Southwest Airlines into its primary East Coast mega-station.
Regional Differentiation & Cluster Role
Busiest passenger airport in the Baltimore-Washington metropolitan area, offering low-cost domestic point-to-point connections contrasting with long-haul international Dulles (IAD).
Data Nuances & Operational Quirks
Direct rail connectivity via the BWI Amtrak/MARC station makes it an intermodal hub; approaches to Runway 33L pass over suburban residential corridors under strict noise abatement.
