ANNAPOLIS, MD — Governor Wes Moore today opened Baltimore/Washington International Thurgood Marshall Airport’s Concourse A/B Connector and Baggage Handling System project. Opening for passenger and airline use tomorrow, the $520 million improvement project marks a major milestone in the airport’s commitment to support future growth and elevate the passenger experience. It is the largest capital project in the history of BWI Marshall Airport.

“We celebrate this project that will serve our passengers, support airline growth, and continue driving economic development for our state,” said Gov. Moore. “By modernizing our airport, we’re showing the world that we are making this Maryland’s Decade and committed to providing an outstanding travel experience for residents, businesses, and visitors.”

“This added gate capacity ushers the opportunity to add more service and prioritizes the airport experience for our Customers using BWI Marshall Airport,” said Southwest Airlines Chief Operating Officer Andrew Watterson. “Southwest launched our first international flights from here more than a decade ago; more recently, we welcomed our first cross-country redeye arrivals and connected our first interline Customers traveling overseas through BWI. We’re delivering more in 2026 with added comfort and choice, including assigned seating. Our longstanding partnership with the Maryland Aviation Administration positions BWI as much at the Heart of our future as it has in the decades we’ve served as the airport’s largest carrier.”

“The opening of the A/B connector is a major milestone for BWI Marshall Airport and for Maryland’s future,” said Maryland Department of Transportation Acting Secretary Kathryn Thomson. “This project strengthens BWI’s role as one of Maryland’s key international gateways—supporting economic growth, innovation and global connectivity—while delivering a more efficient, convenient experience for passengers and meeting the evolving needs of our airline partners.

BWI Marshall Airport serves as a vital travel hub for Maryland and the National Capital region, connecting travelers to destinations around the globe. The airport offers approximately 300 daily nonstop departures to about 90 domestic and international destinations. BWI Marshall Airport generates a total economic impact of $11.3 billion annually. The airport and visitors produce and support more than 107,000 jobs throughout Maryland and the region.

“This multi-year project is a major investment that will shape the future of the airport for years to come,” said Baltimore/Washington International Thurgood Marshall Airport Executive Director and Chief Executive Officer Shannetta Griffin. “We are excited to welcome our customers into a brighter, more efficient and more modern terminal.”
