Some passengers flying into Dulles International Airport today from outside the U.S. say intensified security caused delays and in some cases, missed flights.
The Transportation Security Administration sent out a directive on the new rules Sunday, and reports from several European Countries suggest airlines scrambled to implement the new rules.
Edgar Soudek arrived at Dulles from Rio de Janeiro Brazil, where he says his artificial knee put security officers into frenzy.
Amaka Gboneme, a 24-year-old Nigerian student, says lines were long at her home airport in the city of Lagos but didn't slow her down.
Once international passengers arrive at Dulles, they may move more quickly than travelers at other American destinations.
Dr. Kenneth Button, a public policy professor and aviation expert at George Mason university, says Dulles has more space devoted to security than many other airports have. Button says recent renovations should allow passengers to pass through customs more quickly.
