Reports from the airports
8:50 a.m. Update: Dulles International Airport was fairly calm about 8:45 a.m. Wednesday.
There were no lines at the Continental and United Airlines ticketing areas. A sprinkle of passengers could be seen at the Jet Blue ticketing area.
The biggest crowd was a batch of about two dozen travelers waiting for the Korean Air ticketing area to open.

Ashley Halsey III is stationed at Baltimore-Washington International Marshall Airport. He's seen little use of the new full-body scanners. He hasn't witnessed any pat-downs either. BWI spokesman Jonathan Dean says the day has gone smoothly so far.
