Best Airport Security Checkpoints
No. 19 Baltimore/Washington International Thurgood Marshall Airport (BWI)
Nearly 22.7 million people flew through BWI in 2012, setting an all-time record for the third consecutive year. To meet its growing needs, the airport added a new, nine-lane checkpoint in April 2013 and will soon complete work on a connector permitting travelers to move between concourses beyond security. An additional connector and checkpoint, part of a $125 million development plan, are slated for construction by 2016.
