BWI advances $425M expansion of domestic terminal

Baltimore-Washington International Thurgood Marshall Airport, which is a major East Coast hub for Southwest Airlines, is ramping up work on a $425 million overhaul of its domestic terminal and outdated baggage facilities, the largest investment in the airport’s history. The expansion project aims to improve domestic connections for passengers between concourses A and B while adding new concession space and modern bathroom facilities. It comes as Southwest Airlines, the airport’s main carrier, works on a $135 million maintenance facility at BWI, its first in the Northeast. BWI is one of Southwest’s largest hubs and a central base for its crew in the Northeast. The airline employs more than 4,600 people at the airport, where it operates about 186 flights daily to more than 65 destinations.
