LINTHICUM, Md. - A passenger concourse at Baltimore-Washington International Airport was evacuated Thursday because of an incident at a security checkpoint, delaying at least five flights.<br>
<br>
What prompted the evacuation was not immediately disclosed. The fingerlike concourse known as Pier B, which is used only by Southwest Airlines, was evacuated about 11:40 a.m., airport spokeswoman Nancy Sites said.<br>
<br>
About 1,500 passengers were evacuated and security personnel with bomb-sniffing dogs swept the area. Around 1:15 p.m., the concourse reopened and workers began re-screening the evacuated passengers.<br>
<br>
No incoming flights were delayed, but the evacuation delayed five outgoing flights, Sites said.<br>
