Concourse D at BWI Thurgood Marshall Airport was closed for about an hour Friday afternoon while police investigated a suspicious item in lower level airline space on Concourse D. The focus was in an airline office space located just off the tarmac — not in public areas, said airport spokesman Jonathan Dean.
As a precaution, travelers were cleared from the airline gate area on Concourse D nearest the location and the security checkpoint was closed for a few minutes shortly after 4 p.m. to alleviate congestion in the concourse. The concourse is used by Delta, United, US Airways and Jet Blue.
Officials reopened the concourse at 5 p.m. There was only a minimal affect on airline operations, Dean said.
