The multiyear project, which was delayed amid the pandemic, will renovate and expand the connector between concourses A and B, add new passenger amenities including food and retail concessions and new restrooms, install a new baggage handling system and create larger gate areas to accommodate the bigger airplanes being flown by Southwest Airlines, the airport’s largest carrier.


The project — which BWI Airport Executive Director Ricky Smith told The Washington Post is the largest in the airport’s history — builds on several other ongoing or recently completed improvements at the airport. Most significant is a $48 million expansion to concourse A, which opened in May 2021. Other ongoing projects include a $55 million project to update the airport's bathrooms, improvements at concourse D including new lighting and ceiling enhancements, and a major solicitation process to renew and revitalize its food and retail concession program.
